Hi I have designed a database for a small organization. It is a ver small database. can any one verify and tell me the mistakes in my design. It hardly takes 20 min for the people like you. This is my first step in designing. I am attaching the zip file which contains dbm file and business requirements. Complete physical data model is there.
especially in "category_tests" table i feel that i have done some thing wrong.
Thanking you all.
What's up everyone, I'm new around here and to db design as well...
I'm posting a really rough data model for the first real database I've been putting together.
I'm still in the early stages, and the concepts behind db design are still pretty foreign to me, so there are bound to be many errors I hope to iron out ASAP.
One specific question:
On all of the data models I have referenced, the "OrderDetails" table has no primary key, can someone help me to understand this? Or explain how it is wrong... Thanks
I was hoping some of the experts and advanced users around here could take a look at this and help steer me in the right direction.
Thanks!!!!
Hi all..
This is my first question posted on this site. I have created a survey with questions to be answered. The database is already populated with records of the people's names who were getting the survey. What I need is when the data entry clerk brings up the customer's name on the form, is that they are forced to enter the surveys answers for certain questions before they click the "Save" button. The answers are set up as radio buttons on the form (ie Less than 6 Months, 6 Months, 8 months and 1 Year).
Not sure if a Before or AfterUpdate macro is needed?
Any suggestions would be appreciated. Please email me directly if you have code.
Thank you
Is there any way user can verify the data that its enter correctly, for example I want a button on user form, after every 14 entries when user hit that button it bring the sum of 14 entries.
View 5 Replies View RelatedHello,
I have a fairly complete data model, my question is, how best to create tables for entry where I do not have subform after subform, and subforms in subforms. With subforms for the subforms and subforms on top of that.
I am about to start pulling out some teeth because at this point it sounds fun compared to this!
Do I need to use a query to base my table off of to build my Customer entry form? Or is my only option to use 15 frikin' Subforms? I I use a query, does that cause problems with data integrity?
I am having trouble finding useful reference to this, both online and in books I have purchased.
Normalization is fantastic, I understand.... But besides the crumby Northwind sample DB that everyone and their brother directs you to, is there an actual useful sample to look over that illustrates the use of a normalized data model?
I have grown more than a bit irritated with this, mainly because of my own inablilty to make progress in putting this project together.
I would like to create a simple to use, streamlined systems that promotes efficiency and speed, not a super convoluted system that has 85 subforms on every form in the DB.
I would REALLY appreciate some feedback/direction here, I am about to give up on normalized data and go with a simple flat table approach.
I would rather have redundant data than indecipherable forms that I have to answer incessant questions about.
Thank you,

I am looking for a data model to define and track proficiency/currency.
Example:
You earn a licence to do X. You need to renew your licence every 2 years or so. But also, to maintain currency, you need to do what the licence gives you the right to do often enough, or else you need to do a test.
Specifically, you need to do X a specified number of times N within, say, last 3 months at any one time to maintain currency. If you have lost your currency, you need to do a test/check. So at all times, you need to have N times on record within last 3 months, or a test.
In addition, to do X legally, you also need to document that you have done X at least 10 hours within, say, last 6 months, or that you have another test within those last 6 months. This is independet of the previous requirement (concerning the number of times you did X).
Both requirements must be fulfilled at all times for you to do X legally.
So, any suitable model out there? Essentially, something capable of defining and tracking currency for various ratings and license privileges of pilots would do just fine.
I have researched the 'party' data model but it is a bit too complex for what I'm seeking. For those familiar with it, I don't really need the intermediary relationship from-to tables.
I'm interested in ideas about setting up a data structure that will allow users to search contacts or select contacts in dropdowns regardless if the contact type is a person or an organization.
Obviously the fields needed for both are different and the biggest issue is the name field because the person contacts are
The way I am accomplishing it now is writing the company name, or "first name " & "last name" for a person, to kind of a bridge table when a new record is inserted into the person table or the organization table...kind of inefficient.
Is this a relationship thing or should I just write a function to create a temporary recordset when needed?
I'm looking for methods to verify if an application is working correclty.
Any suggestions?
Thank you in advance.
I am trying to build a table that lists aircraft viewed by plane spotters.
In the “aircraft_spotted” table I have two look up wizards. The first lists the make of aircraft and the second lists the type.
What I am trying to do is filter the models down to the maker.
If I select Boeing I will only get Boeing models and nothing else. The same would apply to Airbus and so on.
I would like to keep this information contained within the table without using a query but if I have to use the query for the model lookup then so be it.
This one is driving me nuts. :)
Hi,
I'm using the code below to check new product# input from a form called frmProducts that is bound to a table called tblProducts.
Private Sub Prod__BeforeUpdate(Cancel As Integer)
Dim varX As Variant
varX = (DLookup([Prod#], "tblProducts", Forms!frmProducts.[Prod#]))
If Not IsNull(varX) Then
MsgBox [Prod#].Value & " already exists as a product #"
Me.Undo
Cancel = True
Else
'do nothing!
End If
End Sub
The problem is that any new product# that you input results in "product already exists".
Thank you very much, in advance, for any help.

Here is my problem:
Say I have a products table:
PRODUCT
========
Prod_id
Prod_name
Dept
Type
:
It is now possible that some of the products can also be a product
group, and a product group would then consist of multiple products.
(Note: if a product is a product group as well, both of them have
the same names. therefore for consistency, if in future someone
alters the product name, that should be reflected for the product
group if that product happens to be a product group as well)
So, I started of by thinking that the products table should contain
a binary filed like "Is_this_a_ProductGroup", where for any product
that is also a product group, while creating or editing the product
the user would flag this field "Yes" and "No" otherwise.
S, my revised products table is like:
PRODUCT
========
Prod_id
Prod_name
Is_it_a_ProductGroup
Dept
Type
:
Based on some earlier suggestions in this forum, I tried to create a
junction table like
PRODUCT_PRODGROUP
=================
Prod_id
Prod_Group_id
and joined the Prod_id above to the Prod_idin PRODUCT table and
created a copy of the PRODUCT table and joined the Prod_Group_id to
Prod_id in the PRODUCT_Copy table.
I would like some help now on:
1. whether this design is really correct?
2. If so, how does one go about the process of data entry through
forms for these tables?
Any help is much appreciated. thank you
I'm sure this is on the forum somewhere but have searched and searched... and had no luck.
I want my date feild to be set to enter a date no more than 2months in advance but a minium of a week in advance.
I have done this lol
week(1)<"">month(2)
I don;t actually have a clue, do you use "" to represent the value? also how do i do this date verify thing :P.
Thanks in advance
Hello,
I need some help. I have a form named MASTER based on a table also called MASTER.
A control of my form in names SSN which stores the client SSN.
On the same form I have placed a subform which has its record source to a table named 21.
What I am trying to do is:
When I enter a new record in my form MASTER, the code should:
1) Verify if in table 21 a record with that SSN already exists.
If YES, skip the code and do not add the SSN. If NO, well, run the appendquery.
2) At the same time, verify if a record with that SSN already exists in table MASTER. If NO, add the data, if YES, abort the code and exit the form.
The form EForms is a menu form I use to access the records.
This is the code. Something is not going right, I think with the end if functions. Any help? I have placed the code in the AfterUpdate event of my control SSN.
Dim mydb As DAO.Database, MyRs As DAO.Recordset
Dim strCode As String
Dim strFilter As String
Dim stDocName As String
Dim stLinkCriteria As String
Set mydb = CurrentDb
Set MyRs = mydb.OpenRecordset("master")
stDocName = "MASTER"
stLinkCriteria = "[SSN]=" & "'" & Me![SSN] & "'"
DoCmd.OpenForm stDocName, , , stLinkCriteria
If Not IsNull(DLookup("[SSN]", "21", "[SSN] = '" & Me!SSN & "'")) Then
Forms("EFORMS").Visible = False
Else
If IsNull(DLookup("[SSN]", "21", "[SSN] = '" & Me!SSN & "'")) Then
DoCmd.OpenQuery ("Appendssa21tax")
End If
End If
If Not IsNull(DLookup("[SSN]", "MASTER", "[SSN] = '" & Me!SSN & "'")) Then
MsgBox "Sorry! A record with this SSN is already in file. Retrive case from E-Forms Menu.", vbOKOnly, "Warning"
DoCmd.DoMenuItem acFormBar, acEditMenu, acUndo, , acMenuVer70
DoCmd.Close
End If
Forms!eforms.lstPreInterview.Value = Null
DoCmd.Close
DoCmd.OpenForm ("Eforms")
DoCmd.RunMacro ("CloseEforms")
DoCmd.OpenForm ("Eforms")
End If
Thanks.
I have a group of databases, with one that I keep global values in (among other things).On initial load, I link the table to other databases, but the linked tables pile up.How can I verify the linked table exists, so I don't have to link it again?

In my transaction table, I would like to find out the latest transaction dates of each family models. It sounds a simple Max function can get the desired result. However model number consists of the first 6 characters for the family model and the rest for the versions (variants). The Max function fails to work in this scenario. Is there any other way to group the model numbers once the 1st 6 characters are identical (the rest is ignored)?

I have a picture stored on a network file share that populates each time a particular form is opened. Every so often we lose our connection (which is a different issue altogether). Right now the error I get after much grinding away, is "Bad file name or number"

Hi,
I've been working hard at learning Access for past two months and spent a lot of time Googling and speeding through Alison Balter's books and at a slower pace the Paul Letwin’s Developers Handbook set (fantastic but I probably need a year to absorb the incredible detail).
I've built a prototype reconciliation tool using the recommended FE-BE model. I opted for a total ADO solution and have had great success in putting together a fast and useful tool for 10+ users.
I avoided using Workgroups in my design and developed my own basic sign-on authority model which allowed an Administrator (don't confuse with Admin user in Workgroups) to add new users who can use the Access app. The allowable users and which ones are signed on are stored in the BE. This all works reasonable well until network issues occur and the signed on user record on the BE is not reset as should be if the user signed-off genuinely.
This is where I realised I need to be able to monitor who is connected to the BE. There is a way of doing that using ADO which I can get to work. I then noticed because all users are signed on with Workgroup Admin as default I could not differentiate between users. I then decided to implement Workgroup authority retrospectively.
I decided to place the .mdw on the LAN with the BE (this seems to go against conventional wisdom but could not workout how else I could achieve what I wanted to). This enables the two Administrators in different places to maintain users via the FE. I use the /wrkgrp command line flag to point to the correct .mdw.
I then started getting all sort of problems . . .I'm still in testing . . . not so bad but deadlines are looming and I'm worried.
Sorry, I digress. . .the problem I seem to be getting is when I open the FE :
Run-time error -2147217843 (80040e4d)
Cannot start your application. The workgroup information file is missing or opened exclusively by another user
I also have problems developing the FE with the workgroup file in place. It seems to complain about another user is locking the FE.
The problem is a little verbose but just trying to paint a picture . . .now, this is what I'm after. . .I need the following ability:
1. Two Administrators who can maintain users. When a new user is added the Administrator chooses a password.
2. When the new user signs on the user is prompted to enter new password.
3. The administrators can view who is genuinely signed on and reset accounts appropriately.
I am currently studying the Access Security sections in the Paul Letwin book to better understand what is going on. It does seem retro-fitting an app to a workgroup model is not straightforward. Admittedly, I should have considered Workgroups in my design before starting (I will know).
Thanks for staying with me if you're still reading . . .any suggestion/pointers would be great.
Lastly, using Access 2000 : O/S W2000
I currently have a query of between dates which the user enters, but when I try to get a total count of model numbers it gives totals for each date. I am trying to get a count of model numbers between these dates with the dates excluded in the grouping.
View 14 Replies View RelatedHi,
1) I am pretty newbie to this access programming, do forgive me if my questions sounds stupid.
2) Basically I create an application in access capturing or production information for my company. now the top management suddenly wanted whats their main concern:- Total Daily/Monthly, Quarterly, Annual Sales (By Model If possible)
3) I start with daily (Lets don't be too overly ambitious).
4) I try to let user select dates from my calender control and reflect daily sales (in Total & By Model break down) insert into my form.
5) Understand someone told me from my previous post in Calender control I can achieve it either through forms or queries, which is a better way. (in terms of flexibility to change for program maintenance/ scalibility) wise ?
PS: Please forgive my ignorance :o:(
Thanks (In advance) & God Bless.
I am working on creating an access database for tracking physical assets linked to locations. I need to make a combo box list to show items other than the current location of the asset. Basically I need it to refer to last enery of the user and define the new possible entries. so we have a unique relationship between location and asset. The assets and location will always remain fixed and there is never going to be any addition. I am creating a web form so that it can be uploaded into sharepoint.
View 3 Replies View RelatedIf my make queries in the data base and the source data base is another .mdb and the table names in the other .mdb which would be used for the queries are the same as those in the data base where the queries would be made......does anyone see any problems with that in the area of corruption or similar.
The queries made would be indentical to their counterparts in the data base where they are made and would serve the same purpose.
It would be a toggle type of thing whereby the recordsources for the forms in question would be changed.
For what I want to do it works perfectly but I am not sure if there would be problems that would only surface with longer term use and varied conditions as opposed to some short term testing.
I have data from a survey with qualitative responses. For a single qualitative question, I moved the ID & responses into a new table and categorized the response according to a bucket/theme, where each column is a new bucket. I now have 10 columns. Each response is represented in 1 or more columns. I used an excel formula to copy the response data into the column itself.
Example:
A1 // B1// C1 // D1// E1//... L1
ID // Response // Cats // Dogs // Elephants //.... Column 10
1 // I like cats // I like cats //(null)//(null)// ... (null)//
2 // I like cats and dogs // I like cats and dogs // I like cats and dogs //(null)//..//
3 // etc.
However, now I'm realizing that Access always wants to show data for all records, or at most I can limit using a WHERE clause in my query.I want to use Access to generate this report:
1. Section 1: Show all responses from the Cats bucket where there is data
2. Section 2: Show all responses from the Dogs bucket where there is data
3. and so on
I know how to do summary values, and I know how to do filtering that apply across the whole report, but this seems like more advanced filtering, where I want to see selective details differently for each field.
First I would like to give thanks to all the knowledgeable folks here who have helped me with my DB to date. It is working and every one is very happy and I have learned a lot.
So now I would like to add some more functionality to this existing project.
My DB is for data input of customers for a drawing. It has the following fields: Id, account number, first name, last name, date/time, score1, score2.
I t is taking a great deal of time for the users to enter in hundreds of entries a day. Most of the entries are customers who are already in the DB. I would like to get the fields to auto fill the data for existing customers say after the account number is entered. So after you put in the account the name and any other pertinent data would shows up saving users from typing it in again.
The first problem I am having is that this is still a data entry form and I can’t figure out how to be able to see the account information and still add new data to the record? The new data is a daily score they get.
Second I haven’t figured out how to call up the customers information from just the account field.
I’ve googled this and haven’t found anything terribly helpful.
i would like in a form for a combo box to be able to select an item from a table and input relating information automatically into other boxes in the form..
I have 3 tables: Table 1 has product code and product description.
Table 2 has invoice number company details, address etc.
Table 3 has product code and product description qty and invoice number..
Table 3 relates to table 2 by the invoice number and table 3 product code looks up the product codes available in table 1 and also table 3 looks up the list of products descriptions in table 1 using the combo wizard.
This means the wrong code can be put with wrong description.
What i would like to know is how i select a product description and the product code in the form fills out automatically?? i hope this makes sense please helppppp!!
