Table Design For A Course Database
Apr 20, 2007
I am building a database for an activity society. There are 2 courses in each season, each course has 10 sessions. Students can be old (returning student)and new.
What we want to achieve is to check student information, the student's attendance situation, how many students in each session, etc.
The table I designed is:
1. Student Detail (student info)
2. Spring 2006 Sunday Course (student ID, payment, each session attendance...)
3. Spring 2006 Tuesday Course
4. Summer 2006 Sunday Course
5. Summer 2006 Tuesday Course
.
.
.
(each new course has a new table)
The problem is for each new course will need to add a new table. I just want to know if there is a better way to manage the data. Thanks for you help!

Hello All,
At work we have a large and messy Contacts list so I decided to set one up using a database.
At present I have 3 tables:-
Companies (custID,companyname,address,etc)
People (nameID,firstname,middlename,lastname,custID)
Phones (phoneID,phonetype,areacode,number,?????)
My problem is this, Some of the phone nos belong to the individuals
and some belong to the company. If a person is replaced at a company I need to reasign the company phone nos to the new person whilst retaining the individuals and their personal phone nos. If a company is deleted I need to delete only the company phone nos. and if a person moves within the company I want the company nos to reasign to the new replacement but keep the personal nos of the individual. Now I see its going to be more complex than I thought.
Can anyone help me with the table layout and links. (nb this is only a simple database relating a person to a company without using departments etc.)
Its main use is to provide phone nos names and addresses quickly.
Many Thanks
Peter

Hi, All--
I am designing a database to capture the data of returned surveys. I want to design the database to facilitate data analysis through crosstabs or other aggregation queries.
If I design a table where each record is the complete survey responses to all survey items in a returned survey, this is not friendly for such query analysis. (In this, each field would be a survey item). Call this the horizontal method.
The other way would be to have a reference table containing the survey items , and have responses entered in a seperate table linked by item id and response id (from a third table containing a record for each submitted survey). Call this the vertical method. This would take more time to set up but would probably be easier to query.
The item response table would become quite long contaiging every item response for every survey turned although each record is short.
Does anyone have any opinion on this, or perhaps a completely different approach that I haven't thought of that would be easy to set up but also easy to query?
Thanks.

I am trying to build a database for a local football team, and am having trouble with the design of the tables. The database contains numerous tables but my main problem is that within the database there are 4 types of people information:
Players:
(a player can have more than 1 guardian attached, eg mother, father, uncle, etc
A player could also be a member of staff eg coach)
Guradians of the players
(a guardian can be attached to more than 1 player, eg two sons playing for the same club
a guardian could be a member of staff, eg manager).
Staff Members
(A staff member can also be a guardian)
Doctors
(a doctor could be a staff member and also a guardian).
What is the best way to approach the design of these tables as i dont want to have to enter the same name, address details etc, more than once for if a person is in more then one of the people information categories.
The main focus of the database is driven by the player Information.
I want to show what guardians are responsible for each player, who the players doctor is, etc.

I am still new at database design, and cant quite come to terms with my project and access way of doing things.
I have to keep a register of people who participate in projects. The projects can be of two different kinds. BUT (here comes the tricky part) The projects are being evaluated on three different indicators, with each one of these having 4 measurements, in the range of 4-0. That was a quick introduction. Now let me break it down in parts.
The people:
I have made a Uniqe identifier (Social Security number (PK))
First Name
Last Name
Department (This can be 4 different departsment) made a drop-down menu type.
The Projects:
Unique identifier (Project ID (PK))
Social Security number
Project Type
Start date
End date
Project type:
Unique identifier (TypeID (PK)
Project type (Cti / Regular)
How might i design this the best way, so i can combine the people with the projects there on. And which type.
There can only be one person, but he can be on many projects. These projects can vary in type. My problem is ensuring there connected proberly.
Furthermore, once the basic design is made i need to make evaluations based on their performance if they are on the projecttype "Cti".
here i need 3 x this:
Evaluations:
Objective (range 0-4)
Baseline reading (range 0-4)
Midway reading (range 0-4)
End reading (0-4)
Success = Yes/NO (here i will do a End reading <= Objective formula).
That was a rather long list, but i have sat working on this in three whole days, and im getting a little fed up with not knowing up-and-down.

I am planning my new DB and am contemplating the best design. It will be used for warehouse stock rotation and control of pallets. I want to track each pallet (product/time in/time out etc) to each pallet space within the warehouse. There are a total of 400 pallet spaces or 'locations' as i will refer to them as.
Now, would it be possible for me to have a table set up for each location? Will access object to having 400 tables in my data base?? Is there a limit?

I have a split database made in Access 2007. Each user gets their own copy of the frontend from a script. I wanted to be able to edit the design view of the backend tables even if people were using the database so I made all the forms use snapshot source and only allowed data updates through VBA macro update queries. Having any form open locks the backend source table from being edited. In fact, I've found that just having a normal snapshot query open causes the message "Either an object bound to table 'whatever' is open or another user has the table open. Do you want to open the table as read-only?"
Is there some way to have a table be the source for a form or query, but still have it designable under most circumstances?
Attempted to late-bind a recordset on form load; result was the same:
Code:
Set rs = CurrentDb.OpenRecordset("Select redacted as ft from tblRedacted ", dbOpenSnapshot, dbReadOnly)
Set Me.Recordset = rs
Set rs = Nothing

Hello everyone. Im relatively new to access, i've only been using it for a few weeks. There are certain aspects that I cannot get my head around.
Is anyone willing to let me email them what I have done so far and the criteria for the database I am making and advise me where I am going wrong and where I need to be heading to get it right?
Thanks very much. Any help will be very much appreciated.

When creating a database is it true that ideally i should avoid using the lookup wizard at table level and instead do that with combo boxes at form level ?

Hi
I have three tables
1 tblAssistFMWork in which is stored the fields JobNumber, SiteRefNumber, SurveyorNo
2 tbltable1 which has the field SiteRefNumber, Address1, Address2 etc
3 tblAssistFMSubJobNumbers which has the fields JobNumber, SubJobNumber.
JobNumber is the relationship between tables 2 and 3 and SiteRefNumber is the relationship between tables 1 and 2. There are other fields in each table but these are the relevant ones for this question.
Each JobNumber will have a minimum of one SubJobNumber but may have many. Each SubjobNumber starts at 1 for each new job so this may look like this in the table
JobNumber SubjobNumber
0001 1
0002 1
0002 2
etc
Each SiteRefNumber may have one or many JobNumbers
I wish to enter the date a SubJobNumber is completed and have been struggling with pulling the record into a form using a combo box because of the need to enter the JobNumber and also the SubJobNumber. So I decided to create a new table tblAssistFMJobDateCompleted which has the fields
JobNumber, SubJobNumber, DateJobCompleted
I need to report on a jobs status ie done or not done, but when I created the query for this it would only pull the records which have a completed date on them.
Could someone please give me some advice as to a way forward.
Thanks
Richard

I have been reading other posts, and this where i should have started from the beginning,I am not very experienced with access (or forums as yous propably know) but can learn anything in no time (hopefully).
I would like to design a database to store all the info about a drag racing event including;
• event info (Event name, track name, event date)
• car info (Car name, gearbox type, diff ratio, engine name,)
• driver info (driver firstname, driver lastname)
• Engine info (make, model, engine compression, carburetor, front carburetor jets, rear carburetor jets, fuel pressure, engine timing at idle, total engine timing)
• Race info (track temperature, relative altitude, milibars, humidity, air temperature, tyre type, tyre size, tyre pressure hot, tyre pressure cold, stage RPM, shift RPM, reaction, 60foot time, 330foot time, 660foot time, 660foot MPH, 1000foot time, elapsed time, elapsed MPH, comments.)
My issue is design of tables and relationships. as you can probably see, obviously cars will do many runs at each event, and there engine setups and car setups(diff ratio) can differ each run. there might also be different drivers for the same car. weather info like track temp etc also change from race to race so I think it is possible I might need some sort of race time as-well. My main reason for the database, apart from organizing all my results would be so that I could do a run at an event and search previous races by the current runs weather info (relative altitude, milibars, humidity, etc) as to set the car up similar to keep it’s elapsed times consistent. Please, please, please help as I am at a total loss.
Thanks in advance!!

Hi all
I've created a database from scratch. No data attached anywhere yet - I'm planning to input the data manually through my Form.
Well I have about 15 tables - CustomerInfo_tbl is the main table with the field RefNumber my primary key (it's an Autonumber which is sequentual). The rest of the tables are normal tables which I plan to link.(these tables also have RefNumber fields which are LongInteger) All the tables have about 10 fields in them.
So then I have 2 choices - I can make one big table (about 150 fields) or 15 tables with 10 fields each and the join them. I heard somewhere that it's better to have small tables and then link them up. So I'm going the smaller tables route.
I'll tell you what I did. I joined all the tables to my CustomerInfo_tbl with a one-to-one join. Then I made a Query, and then I set the RefNumber of the other tables equal to the RefNumber of my CustomerInfo_tbl.
I have 1 problem. When I enter some data into the form (I do not enter all the fields I leave some blank) it isn't displayed in the query, but it is displayed in the appropriate table. Only when I enter all the fields it is displayed in the query correctly and also in the tables.
Any help? I hope I made my question clear enough.
Thank you in advance.
Cheers

Hi, i got back to working on databases again for the first time in years and ive got confused on the offset.I went to set about desigining my tables and cant figure out how to do it.most of its simple stuff however this one bit stumps me.
Im designing a database to hold stock information in work we manufacture parts for rally cars and when a customer rings up i need to have the price at hand.I can store the prices etc of individual parts,however some people request kits which would have there own stock number and all the same relevant data i.e. Item Name,Type,Cost,Number in stock,Selling Price.......
These kits would consist of several items from the stock table.and when a kit is sold it will be inserted into the Sold Items Table together with the other individual parts a Customer may order.
Any help would be gratefully recieved.

Hi all
I have a new project but before I get started, I need some advice on design.
I'm designing a student report card which I'll implement for 1300 students next year. The concept is an ongoing electronic markbook where teachers update the progress of each student and then at the end of the year print a report based on the captured data. The data is then passed on to the next teacher the following year.
My problem is data storage. During the course of a year a teacher may mark off up to 550 things a student can do. After 7 years of schooling (7 x 550) this amounts to a large amount of data. The thing is, I could reduce the number of fields if the multiselect list box stored multiple pieces of data. Option groups are no good because only one piece of data is stored and I certainly don't want thousands of check boxes.
Basically, I'm looking for a way to store multiple pieces of data in the one field. I'm also looking for a way in reducing the amount of clicks (i.e. one click instead of 2 to enter data)
I can't delete data because it's an audit requirement to keep it.
Any ideas??
I appreciate any help

Can someone help me out with the design of my database? I currently have it set up one way and I am running into problems when I need to update information?
here are the attributes I have to put in the database for Printer cartridges:
ProductName
Manufacturer
Category
ProductCode
Price
Weight
Description
--------------
There can be numerous products with the same name
(for example: C120 is a product name but can be made by HP and by Canon)
There can be numerous products with the same ProductCode
(for example: F416301700 is a product code but can have multiple products with that code)
Currently I have it set up like this:
3 Tables
--------
PRODUCTS
ID
PRODUCTNAME
MANUFACTURER
CATEGORY
DETAILS
ID
PRODUCTCODE
PRICE
WEIGHT
DESCRIPTION
COMBINE
ID
DETAILS$ID
PRODUCTS$ID
-----------------
I have created that combine table to link the two other tables together.
I am running into problems now when i want to update a product and I don't know where to take this from here. I think if I have a better design from the get go it will prevent problems in the long run.
Can anyone help me with this?
Thanks

Hi, I’m fairly new to access and I’m creating (well, want to create) an employee database. I was wondering if anybody has created an employee database that keeps track of employees information like; personal information, salary, training the employees have taken, performance reviews and much more and if so do you have any suggestions on the design. Pretty much this database will be an electronic version of the employees personnel file.
Or does anybody know of any sample databases, not necessary an employee database that have been shared here in the past that I could look at and get ideas (formulas, qrys, tbls. etc.) from there.
Thank you.

Hi,
I am designing a db for my car event that happens once a year.
It needs to hold car info like engine specs, car specs. Entrant details and event details, merchandise info.
I started out designing on paper (Can’t stress how much this helped a definite must for all noobs and experienced I would imagine) and went from there.
Ended up using northwind and modified it to suit my situation.definately recommend this to beginners as it gives you a good look at databases and great starting point. anyway this db has everything I need I think, the db is for holding info about participants in a car event. There is a form that the entrant would fill out asking there details and the car details. There is also a section on the form to buy merchandise as the car event has its own T-Shirt and DVD.I have added this into the database but I am having trouble finding where to put the T-Shirt Sizes.
E.g. there has been 3 events so far (1 per year), car event 1, car event 2, car event 3.each event has had a T-shirt. this t-shirt comes in sizes, xxs,xs,s,m,l,xl,xxl,xxxl,xxxxl,xxxxxl.my problem is do you add the same t-shirt in the products table 10 times just with different sizes.
also the Entrants form has subform event, where you select the event each year as to not have to enter entrants twice.i can not seem to figure this out either.
Once you look at the db you will have a better idea.
The database only has a very standard form for getting around while I complete the design, all the beautification will come after this stage.
Any other ideas would be greatly appreciated.
Thanks

I am combining 12 Databases. I have split all 12 between the server and the desktop. My question is “Should I combing all of the data table on the server into one database or should I leave all of the individual application data tables in separate Databases on the server”. Additionally, is there a limit to the number of tables an Access DB can handle? My inclination is to keep the functionality separated but the problem I have is that some of the functionality within the applications overlap. Recommendations!

Hi Guys,
I have sort of problem - I'm trying to desing the database for one of the organisations.
The entities are: Family, Child, Referral, Voucher, Receipt, Provider, Activity.
That's ok so far. I've been asked to do the option for the new address of the Child - in case if they move to the new place and keep the old one as well.
Family table is the 'child table type' for the Child table - family can have more than one child, but one child can be part of only one family (one to many relationship).
I thought to make a seperate table 'tblAddress' and store all addresses in this table - then link them to the family - this however requires from me to have additional field for - for instance - second address, third address, which in case there was no change in address would remain empty value.
The other option - which obviously is absolutely waste of space is to add straight away additional address fields in the 'Family' table itself.
Don't you know of any other, more appropriate solution?
If you need more detail - I can send the copy of the database which I have created so far.
I would appreciate any help.
Thanks,
Scabro

To all you access Gurus
I have been asked to look at setting up and access database to do the following
To keep a record of pupils and 9 tasks the pupils have to do and also the total amount of time it took a pupil to do this task
They have a total of 25 Hours to do all tasks but this is spread out over the year.
What I need is someone to tell me the best table layout to do this
The pupil record has to have the following
First Name
Surname
Form
Total Hours taken for all 9 Objectives
A description of what the pupil did to achive each Objectives
record if that task is complete
Also Date Task was Complete
I have done a test database with just one table in it and inside that table
had all of the above but apart from name, form and total hours I repeated the rest nine times.
This just does not seem right
What I want is to pull up the pupil name and then select Task say from a Drop down box this would then insert a new field if it did not allready exist in pupil recored and then you can fill in the task details of course if the field/s all ready existed then to open that up to allow you to update this
It would then need to update the total Hours field in the pupil record with the hours it took to do that task/objective.
I have basic Access knowledge but i cannot think of best way to achive this can anyone help please

Hi,
New to forum. Beginner/Intermediate Access Experience.
Here is what I am trying to accomplish:
The database i am creating will basically need to have a user check-off a list of Fire Extinguishers that he has checked, on a monthly basis. For example, the user will enter a date, and then a form with a list of all the extinguishers will pop up, and he will place a check mark by each one. When he enters the check mark, that date will be stored so that we have a history of when each extinguisher was checked and by whom (using initials or something)
Currently, my design is simple, something like this:
tblUser
pkUserTableID
fldUserName
fldUserInitial
fldINSPECTIONDATE
tblExtinguisher
pkExtinguisherID
fldExtinguisherNumber
fldExtinguisherManufacturer
fldExtinguisherType
fkUserTableID
My question is this:
-Am I going down the right track with the 2 tables?
-Do I need a third table to Store the Historical Data?
-I am not quite sure how to layout the form so that all the extinguishers are listed.
I know these questions may seem vague, but any help would by highly appreciated.
thank you.

I am trying to set up a database that manages responses to a variety of survey questionaires, and I want to know if I am on the right track before I proceed. Sorry if this gets a bit verbose:
Here's the general 'business rules':
1) There are many different historic survey types. Some have also not yet been defined.
2) A specific question may appear on more than one survey type.
3) Each survey type can have a different number of questions.
4) The 'valid' answers to a survey question fall into two general groupings:
- multiple choice (variable number of choices)
- freeform text (and "other__________ " could be a multiple choice response)
5) There will be a lot of repetition in the multiple-choice choices. For example, there will be lots of "TRUE/FALSE" or "YES/NO" questions, lots of 'Rate the following on a scale of 1 to 5' type questions, etc.
6) Some of the multiple choice valid-answer-sets may be more unique, such as '200,400,600,1000,other'.
7) We (sometimes) want to capture such information as 'don't know', or 'answer illegible' or 'not answered' or 'don't care', but these can just be more 'pre-set' choices in the db that do not appear on the paper forms
After some whiteboarding, I arrived at the attached db structure....

Hello, I'm designing a database for a small country club for skiing, and am running into an issue. One of the goals of the database is to keep track of how many times potential members try out the skiing, currently we are storing the dates they ski in the same table as all of their personal information, We need to keep track of each individual date, so there are field for first visit, second visit, etc. We need to be able to run a report in which it can search the six date fields and pull up all records within a date range, is this possible, or should I create an additional table which stores dates, and is linked to the guest ID?
your help is greatly appreciated!!!!!

I have 7 tables:
Booking - BookingID
Course - CourseID
Company - CompanyID
Materials
Materials_on_course (had to have this in order to avoid many-to-many.)
Employee - EmployeeID
Employee_runs_course (had to have this in order to avoid many-to-many.)
I'm stuck with the Course and employee thing. Each employee has an expertise or two, and therefore each course has an expertise needed to run it (a specialist if you like).. so the PK in 'course table' is Course ID, you cannot have two PKs in one, so would it be right to say that the 'expertiseID' would have to go in 'Employee_runs_course' ?.. what would i do then? place 'expertise ID' as an FK in both employee and course tables?
Extra info:
Clients (tblCompany) can book one or many courses
A course can have one or many bookings made for it
A booking has one or many employees/courses
An employee can work on many bookings (obv if available)
Each employee has one or two expertise (usually only one)
and therefore a course has on expertise attached to it.

If you have a better way of designing it, shoot!

Hi,
I want to make an access database but Im struggling with the relations a bit.
I understand the one-to-many and many-to-many concept but seems like there is more then that
I want to make a database that keeps track of things we lend.
I have several items with different properties we lend out:
eg
TANK
-ID
-Volume
-Weight
MACHINE
-ID
-hours
-fueltype
...
I made the following tables to keep track of it:
RENT
-ID
-Customer
-...
One-to- many relationship between these
RENTLINE
-ID
-RENT_ID
-Item
My problem lies with this Item.
I want this Item to have a relation with the ID of the different items we lend out. there needs to be a one-to-many relation here.
one rentline can exist of one TANK OR of one MACHINE.
A TANK or a MACHINE can exist on many orderlines.
So I made 2 one to many relationships from Rentline to the id's of Tank and Machine
the problem is that Access does not let me fill in the rentline with the id of a item. If I fill in the ID of a TANK it says a ID of a machine is needed and vice-versa.
I tried to solve it with an intermediate ITEM table that looks like this :
ITEM
-ID
-Sort ( Tank or Machine)
-ItemID (Id of the tank OR the Machine)
But this generates the same issue as directly in the rentline...
I guess this is pretty common stuff Im asking here but its confusing me like hell :(
thanks in advance for all advice
