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 :(
I would like to make a human Resource database that shows in a tabbed form some informations about our employees.
I would like to show per employee: tab 1: general info (name, address, starting date, type of contract, department) tab 2: salary history tab 3: capabilities -whether they are available YES/ NO tick field and for the department the person is assigned to
I am thinking of the following tables: Employees - EmployeeID, Name, address, starting date, type of contract Department - DepartmentID, Capabilities Salary History - EmployeeID, Date, Salary, Notes EmployeeCapabilities - EmployeeID, DepartmentID, Capabilites [Yes/ No]
The only problem I have is to make the correct relations between the lot of them.
i need to design a database but am abit unsure the best way to go about it and am looking for sum thoughts and suggestions.
I need to create a database for part numbers and competitior cross references, however the problem i have is were we list one number a competitior could list upto 5, and where we list 5 numbers a competitior could list one, so there could be literally thousands of duplications per competitior both ways around.
for instance we list DG897, our main competitor would list AB458, AB459, AB 487 etc. Basically the part number is a car part, and we say one part number fits serveral vechicles, but out competitior says its one part per vechicle. (sorry for the poor explaination)
has nebody came up against a database where the possibilty for duplications is so high before and how did they go bout designing the tables, I am far far from a regular user of access, however am very keen to learn.
I am designing a database for my company that keeps track of new classes and new courses created. I have a form for each with the create a class form taking the course title from the courses table/created course from the create a course form.
Here's my dilemma. I want to use cascading combo boxes for class location, facility and room but I think my table structures and relationships may be incorrect.
Here is a list of my tables and their fields:
tblClass ClassID (PK) CourseID (FK) InstructorID (FK) StartDate EndDate StartTime EndTime ClassMin ClassMax Materials (yes/no) MatNotes EmpID (this is the ID of the employee who requested a class creation) LocID FacID RoomID LogID (Logistical Coordinator ID, if applicable)
Course CourseID (PK) CourseName more...
Employee EmpID (PK) FName LName more...
Instructor InstructorID (PK) FName LName more...
Logistical LogID (PK) FName LName more...
Locations LocID (PK) Location
Facilities FacID (PK) Facility LocID (FK)
Rooms RoomID (PK) Room FacID (FK) LocID (FK)
When I run a query with class, locations, facilities, and rooms no information shows up. If I run the query with the relationships between facility/room, facility/location and room/location removed (leaving the only relationships between class and these three) it works. Why is that? Shouldn't there be a 1-M relationship between Location, Facility and Room? Or, should there be a M-M relationship and I should create tables with each PK?
I apologize for the long post but this has become quite frustrating (despite the simple logistics).
I have constructed a seven table database for dealing with holiday cottages.
The seven tables are:
Bookings Cottages Customers Ratings Owners Regions Sales Reps
I have created the 7 tables and created the primary keys (BookingID,CottageID,CustomerID,RatingsID,OwnersID ,RegionsID,RepID)
The ratings table because cottages come under different ratings (Family, Sporting etc..).
I need to create a form which
*Adds a new booking, and also adds the new customers details *Checks the avalibility of the cottage for the chosen week *allows the user to choose a rating from a combo box, which then filters the cottages availible for selection in that category.
If anyone could help me with this I would be very grateful, I have emailed my lecturer but he is not replying and the assignment needs to be in on the 12th!
While searching for Access help through Google, I found your forum which has greatly helped me in building my database in Access. I got all answers through your forum for many of my doubts and ‘How To’s. I thank all the members for their excellent and simple way of explaining for a novice like me.
As to the Database I built, it is almost complete and working fine. I have built a switchboard with menu choices. I have distributed this to all my colleagues and they are using fine.
I have three problems still to be addressed. I have tried to protect my database tables, forms etc through the security wizard, user permissions etc. But nothing is working. I have hidden all tables, forms etc. and unclicked the ‘Display database window’ in Startup so that only the switchboard is visible. I have also changed the switchboard properties to cover the entire screen and no maximize/minimize/close button. When a user double-clicks the desktop icon the database file opens with the switchboard menu. There is an Exit button in the switchboard which the user can click to he can click the close button of the Access window. Apart from this, the user can do nothing to corrupt the tables, forms etc., so I believed. However, one colleague clicked the ‘View – Design View’ in the Access menu bar and the Switchboard became ready for modification. Is there a method to block the View – Design View’ option in the Access menu bar?
My second problem is that we want a new database file first of January every year. Is there a method to create a new DB file with the same table, form and settings from within Switchboard? (The only option I found was to copy the DB file to another location, delete all records and rename it for the new year). Is there any other procedure?
My third problem is that I designed a Crosstab Query as given in the Help menu with criteria LIKE “*” & [Enter any character to search by: ] & “*” but when I execute the query it displays all records containing the character entered. This is not what I want. My search criteria everytime changes (it is text based). So I am unable to save Query form with a specific criteria as it will execute only defined parameters. Is there a way to make Query form where any user input (i.e. any word or number) is taken for search?
Hi, All I am designing a database to keep track of part prices and their trends, the part numbers and all their related information are stored in a "Unified Parts Database" containing all pertinent information about the parts, their vendor, current price, material, sub-material etc...Now in the new database I am making I wanted to have one table that has these field.
The tables name currently is "Main", fields are as follows:
and then I have a "Prices" table which stores the different price changes for each part number:
PriceID (PKey) PartNumber Price PriceChanged
now I what I am trying to do is have the "Main" table pull all the part numbers and their descriptions from the Unified Parts Table which is a linked table and I am not sure how to get it to fill all this stuff automatically inside a table not a form, would a "Main" Query be the correct way to go and completely skip the "Main" table??
Hey guys , I was wondering if you can help me with this one cos I am clueless. I am in charge of updating this website which sells stationeries, office equipments etc. Well the catalogue in our website is kinda messy since there are lot of the product items inside the catalogue page which has no images.It is embarassing for those customers who wants to buy a product but couldnt see the picture of the items. For example , http://www.mellon.com.sg/catalogue/s_searchresult.asp?searchby=category2&searchfield=laminating%20materials.
The product items are generated from the Access database where I also included a column field in the database called "Picture" where those product items with images have checked(tick) in the box and those without images are unchecked(no tick) in the box I am not sure if I should filter anything or set up any criteria for the pictures from the database. I need help as i am not a total expert in Access
I'm an audio/video technician at a college and wish to use Access for a simple camera booking system, but do not have time to go through all the extensive help menus and tutorials about this program, and none I have viewed seemed to help.
I want four columns in the table. First, the user inputs a student ID number. Now my first problem is that I want the student name to appear in the 2nd column after entering their number. I don't know where to create the list of names or how to link them to their student ID numbers.
My second problem is I would like the 4th column simply to display the date seven days from the current one (as in whenever the db is used) for the return date without having to input it manually.
Any help towards these 2 problems would be most appreciated, and thanks in advance.
here is a link to my website http://www.justevents.biz if there is anyone who would be kind enough to look at it and tell me how to build an access database for the categories and search by zip, etc. i would be greatly appreciative. I have tried all the tutorial helps and built about 15 different databases and can't get a single one of them searchable under any circumstances. I have tried all I know to do.
I want the value to be displayed in a combo box from database , when the form_load is in action

I am looking for a database that can keep up with the full management issues relating to single family houses. Some are on a lease. Some are on owner-financed by use. Any help would be great!
I am willing to pay a designer to program this database for me. Email any samples or questions to babyfacedavid@yahoo.com
I am quite new to access and i can grasp things quite easily.
Basically i am make a stock control data base for a food company. I am making it so theres an order table and a stock table. Basically i want to know how to change the Quantity avalible in the stock table fom the orders table.
I dont know if i have explained that very well. But basically i have related the product name in the stock table to the product name in the order table. So i can add a number so that that the quantity of the product will change on the stock table.
If there are any easier ways of doing this rather than having 2 tables it would be useful
Ive tried all types of things and i cant get it to work. Any help would be very much appriceated.
I'm kinda lost in here so I'd appreciate some help in pointing me in the right direction please. I've no doubt the answers are out there but I'm having trouble finding what I need, probably because I don't know how to frame my questions!
Basically the story is this - there are three guys covering various aspects of the business, they each visit three separate locations - all guys visit all locations. We have made a "big plan" that has 14 key deliverables in the locations as a "region" .
For each Key Deliverable there will be Actions, some Actions will be done in all locations, some might only be needed in one location. Each owner will describe the Action and link it to the Key Deliverable it supports.
What we want to do are things like Take Location 1 and Guy A and show all the things he is doing to support Key Deliverable X.
or
Show all the Actions in Location 2 that are being done to deliver Key Deliverable Y by all Guys.
That sort of thing - progress reporting and identifying where we have nothing happening to support a Key Deliverable or too many actions in one Location etc
We have all our plans in Excel spreadsheets at the moment, each guy fills in a sheet and at present the idea is that we copy and paste it into the mother of all spreadsheets to present to the Gods - it's not happened yet because it's clumsy and well, it's my job to present it and I thought "there's gotta be a better way!" I can import the sheets into Access but then it all gets a little tricky and I run out of tallent.
OK so if you've read this far you're wondering if I have any idea what I'm talking about when it comes to Access! Well I am pretty much self taught and rusty but I can see that Access could help us get organised and
My limitations - I'm using standard Access 2007, I doubt corportate IT security would allow me to add in any useful plug ins or upgrades etc.
Am I using the right tools? I'm limited to MS Office really so I mean should I stick to Excel or carry on pursuing an Access solution?
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 ?
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.
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!!
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.
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.
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.
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 dp3133
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.
