Very General Table Structure Question.
Nov 5, 2005
i understand the necessity of foreign keys to link tables and create dynamic data structures..
believe it or not i have a degree in this subject, but am finding one little issue quite confusing...i shall illustrate this with an example...
THE RIGHT WAY TO DO SOMETHING - 2 tables.. table1(DRIVERS) table2 (JOBS)
DRIVERS
driverId
name
phone
JOBS
jobId
date
driverId
each job is carried out by one driver, and drivers can do many jobs throughout their lives...obviously. i learnt that in good practice, the above two fields should be used to link these 2 kinds of tables together..
to my knowledge.. to link the two tables like this in access.. i would view the 'Relationships' and drag one field to the next.. so the little line joins them and everyone is happy..
HOWEVER, i have created this database and have used this method...imagine my user adding a job to the database.. all i want them to do is choose the drivers name from a dropdown menu for each job. to acheive this i have used the 'lookup wizard'... this successfully associates the chosen driver to that job and when you query the database, the results are valid.
this link i have created has nothing to do with the Ids as illustrated in the above example. what i need to know is if i link the two tables in the 'proper' way using the Ids.. how can i allow my user to choose the drivers name when entering a job.. rather then choosing the drivers Id number on the form because that would be confusing...
i hope this post wasnt confusing..
am i mad...someone please explain to me???

I am working with Access 2007. I have a pretty good working knowledge of access. Here is my problem. I have a warehouse which supports four departments. The warehouse floor area is segragated into four areas. Area 1 department 1, area 2 department 2, and so on. Each department uses the same commodity, so I will have four of each item, belonging to each department. The storage locations will be unique and not repeated anywhere in any department. I receive and issue items for all departments.
The problem is how do I structure the tables and queries to receive an item for department 1 adding it to department 1 only and not have the item added to another department with the same item. Also to issue the item from a department 1 without effecting the on hand balance of any other department. I am too the point of creating 4 separate databases one for each department.

I have a need to copy a table structure from an existing linked table in the backend
i have done this by
a) copying the table structure into a new table in the fromt ebd
b) exporting the new table into the backend
c) dropping the table in the front end
just wondered if there was an easy way to do this directly in the backend?

We are currently using Access 2007 for all our database needs but so many different people have had access to changes things that now they are so convoluted that my boss is wanting me to build a brand new database... Is there a way to take all the tables in one database and migrate them over to the new database that I am building?

I need to daily import files that start with same name, but the remaining part will be Bill of lading ID (e.g. TEST_BOL 1234.csv). The next day will be TEST_BOL 1235.csv) and so on. I need for Access to import the file based on the "TEST_BOL" into my database and then delete the file from the folder. I don't know how to initialize Access to look for the prefix and import in.

hello all, I am very new to access (my background is in VBA Excel, but I am not using VBA for access yet).
I was wondering if some of the more advanced people can give me pointers on how to accomplish (or work my way) to make the kind of form I am trying to do.
What I am trying to do is the following:
I have a vending company with couple of products such as espresso, latte, black coffee, etc.. (all of the products are sold at the same price for each customer, so I might sell the products for company A for .75, but for company B for .55 etc) and I am selling these products to many clients company A, B, C, D, etc. As A start I created a table with my products, then I created a table for my clients (this one includes name, address, contact person, and machine number ).
I would like to make a readout input form where it would get the customer name, machine number, each of the product's total for the readout period (this is usually every week), and the date of the readout. Now I would like the form to add a record in a table for the client machine number that was selected and maybe also in another table for the overall machine ( I am not sure how queries work, and weather I would need that or I can use queries for it).
My ultimate goal is to be able to do the following with the data:
- check (and perhaps graph) the overall statistics for a each of the products for all clients
- do the same for a certain client
- do the same for a certain machine at a client
- check the overall sales of all products to all clients for each month of the year
- do the same for a particular client or for an individual machine
- do the same but for each year
I have done all of this in a VBA Excel based program but I was hoping to change the program to be access based instead of excel based, since this would make the data more centralized and easier to maintain, backup, check, and update.
So if anyone can post any hints or suggestion about how I should build my tables, the usability of quarries, and especially the construction of the forms I would very much thank you for that, since these are my first days getting to know access and I am absolutely confused with it, all the language you are supposed to put into text boxes, combo boxes etc....
Also if anyone knows of any good links to some online tutorials would be great, since most for the tutorials I found on a search was for constructing a for or a query using the wizard, but with no real discussion of how to bound the data to certain fields etc.
Layth
I thank you all in advance.

I'm trying to copy the structure of a table to make a temp table. I'm using CopyObject (which also copies the data). So when I delete the data from the temp table, it also deletes data from the source table. Is the data linked? It should just be deleted from the temp table. Below is the beginning of the code. I've stepped through, and at the last step shown, the data in the source table deletes.
Code:
Dim strFile As String
Dim temp As String
Dim tbl As String
Dim db As DAO.Database
' error handle
On Error GoTo F_Error
[Code] .....

Here’s a little scenario:
An engineer requests that “x” amount of computers are ordered for the company. The estimated costs of the system(s) are determined. The estimated cost of the systems is forwarded to a manager, and the request must be approved by a manager before the order is placed. Once the manager approves the request, the order is placed through the ordering company. After the ordering company approves the order, an order number is assigned and serial number(s) specific to each computer is associated with that order number. At this point it is possible to track the order status via existing programs using the assigned order number and serial numbers. After it is determined through the existing software that the order has been shipped, invoiced, and received by the Receiving department, I need to physically go pick up the systems and submit them into my Central Inventory. From the central inventory, systems will be checked out to employees as needed, checked back in when testing is finished, or transferred internally between employees......

I have been reading up on normalizing table structures. I have this database that I am working on, to work as a hiring database. It should hold information about people applying to the law firm I work at.
I am looking for advice on if this table structure is normalized and sound. I am also looking for specific help on creating good forms.
Thanks for any help that can be given!
ps. I am attaching a zip that has a jpg view of the tables and their relationships, as well as the db with the table structure.
I would love any and all advice. I want a very clear concept for this db before I do anything!
Thanks again!
:D

I was having a discussion with a friend of mine about this... and I couldn't come up with the best explination. Hopefuly someone here can point me in the right direction.
He has a table
Recipies(Id, name, item1, quantity1, item2, quantity2, item3, quantity3, item4, quantity4)
I don't believe that this is the proper way to create a table. What happens if you happen to come across a Recipie that needs 6 items?? or more??
After researching it, I believe it violates 2NF. Is this correct?
Instead I think a better structure would be
Recipies(Id, name)
RecipiesIngredients(Recipies.ID, Ingredients.ID, quantity)
Ingredients (Id, Name)
The problem my friends sees with this method is the fact that the Xref table will get giant.
In the example... Speed is of utmost importance, as the tables will most likely contain thousands of records and be queried against frequently.
Thanks for any input.

I need some help trying to setup tables on a new database. I want to setup a house analysis database where I can evaluate each room for it’s condition broken down by feature. I can’t seem to figure out a good way to tie all the rooms and evaluations back to that house’s address (primary key). I want the fields to work as shown below with the room evaluations tracked to each room and house address. If possible I would like to be able to enter the as many room names as needed for each address.
House Address
Bedroom 1______________Bedroom 2_______________Bathroom 1
Ceiling condition –Good____Ceiling condition-Fair____Ceiling condition- Good
Floor condition – Fair______Floor condition – Fair____Floor condition - Fair
Wall condition – Good_____ Wall condition – Bad____Wall condition - Good
Can someone please explain to me how I should structure the tables to work. As a novice Access programmer I am out of ideas. Please help me!!

What's the best way to setup this db?
I have the following information:
Company
Company ID
Program A
Program B
Program C
Program D
2000
2001
2002
2003
2004
2005
The years indicate the year the Program participated in the company. For example, Program A participated in Company Z from 2000 to 2005, Program D participanted in Company Z from 2001 to 2002.
Should I have a table with the Companies and Program A and the years from 2000 to 2005
and a table for the Companies and Program B and the years, etc? I was going to add a yes/no field for each program, too. There must be a simplier way.
I want to be able to query participation of workers in any of the programs.
What is the best way to set this up?
Thanks.

I've got some tables, and I want to make sure I relate them in the best possible way.
Table1 has a one to many relationship with Table2
Table1 has a one to many relationship with Table3
Table2 has a many to many relationship with Table3
Would it be best to set them up this way or is there another way that would be better?
Fields for Table1
Table1_ID
.
.
Fields for Table2
Table2_ID
Table1_ID
.
.
Fields for Table3
Table3_ID
Table1_ID
.

i have been asked to design an access databse for a friend who is a bricklayer. He wants to use it to store all the work he does so he can produce his timesheet quicker.
He works on building sites and has to show a plot number next to all the work he does. He wants to be able to search for a plot number and see what jobs he has already booked in for a particular plot number.
For example, if he is working on a block of flats, each flat will have individual plot numbers. If he is working on the outer wall of the flat his timesheet has to show all plot numbers for that block so he will normally show this as plots 100-110. however, if he works on an internal wall in one of the flats he will have to show just one plot number on his time sheet, for instance plot 104.
my problem is that he wants to be able to search for plot 104 and have it list both jobs he has done even though one job is shown as plots 100-110. How can i structure the database tables to allow this to happen.
Any advice would be much appreciated.

hi everyone,i'm new to access and despite reading quite abit im just not grasping how to set up tables and relationships for what im wanting to do.I need a customer contacts table/form to keep track of my customers info (name, address, etc) & who's placing orders, easy enough.Now with some of my customers its always the same person who places the order but with others it can be anyone of up to about 15 different people who place the order each one can have their own direct phone no.So what im wanting to do is create a customer contact table/form and then linked to that who in that company placed the order with their phone no. Ideally i'd like it so once I have entered the info I can just use drop down menu's to select the company name then it opens up a list of all the people who I deal with in that company so I can just select the person/phone no who is placing the order.Can anyone help & advise me through best way of doing thisthanks alot

Good morning,since this is my first post I hope I'm not making to many mistakes.I'm making a database for school in Access 2003. In this database I have 2 parts.. A part for Patch connections and a part for PC repairs. The PC repair part is doing okay. The patch part is where I'm having some trouble.I don't exactly know how to start with it, and I'm hoping someone here can help me out.The form, I want to make based on tables should look something like this:A ComboBox filled from a table with about 10 entries in it. (Patchkasten)A textfield in which I have to enter something like this: XX-00 (x stands for alphabetic - 0 stands for nummeric)(Patchnummer) This will have around ~3000 entries.Those 2 should somehow be connected in a table as 1 field. (if that is possible offcourse)If not, is there another way to do something like this, because the combination of (patchkasten)and(patchnummer) has to be unique.. And at last a combobox (ruimte) with around ~ 150-200 entries.Now my question is if someone could help me setting this up somehow. Help would be appriciated.Thanks,F3dde

i am currently working with a human resource outsourcing company. we deploy contractual employees to different companies.
we usually use ms excel in keeping records of our employees, now my boss wants me to create a database using ms access. this is my first time in creating database using ms access.
here are the headers that we used with our excel database:

- Pay class (daily or monthly)
- Basic Rate
- Allowance

- Mobile no.
- Civil status
