I have been tasked with producing a Service Catalogue - essentially, a list of services offered by IT to our business customers.
The Catalogue is a repository of information related to the service - such as, Service Info, Business Info, Server names and location, DB info, Batch and Online times, Network Info (and the list goes on).
Obviously, these are high-level categories. Within each of these (for example. Business Info) there is more granular info such as, Business Owner, Supported Business Area (there can be more than one) and Business Criticality.
Given the data and the fact that some category items may have one or many values for any given field (DB names for example), is this something worthy of a DB?
I have tossed this around in my head and I can't get away from the notion that I will require multiple tables with untold fields (yikes - scary thought!)
I have attached a rough DB but before I put any more time and effort into it, I want to know if I am on the right track.

A very good morning to you all!
Does anyone know if this is at all possible. When I wish to process a payment for a customer within my database, rather than visit paypal and entering payment information, is there a way by way of API or similar that I can automatically go to the site and have the payment amount entered for me using data from a form within my database?
It may be too much of an ask but I thought I would at least ask the question..
Thanks
Gareth

I am working from an existing database which is just two table. The main table has a massive amount of redundancy and duplication and needs splitting into, at first glance, 5 tables.
After I have run my various make table queries and added a Primary Key and FK field to the new tables how do I populate the FK with the Parent PK.
I thought I could simply add all the fields from the new table and then create an adhoc join in an update query to populate the PK to the FK. When I do this however I get "You are about to update 0 records"
I have tried the table analyzer but it doesn't give the correct options to split the table the way I need.

I have a performance evaluation db in MSA 2003 I am about done with. I had asked a question and got a helpful response. However, the response mentioned normalizing so I hit up google for more info. My db is not normalized, but after reading several sites, I don't see why I need to normalize it. The sites also said there are not a lot od reason not to normalize. I can't believe I just stumbled onto one. I have fields in my table that need to be scored on a 1-5 scale. I can see making a separate table for scores. However, the list of questions never grows or shrinks. It's a standard format that asks the same 20 or so question every time. Is there a reason to split the table into multiple tables? If so, would it be the scores vs. employee info tables? TIA for your assistance!

Hello I have a question.
I work for a company that had someone set up an Access database that generates work orders.
That person created a single LARGE table. 107 fields in the table. over 3000 records created so far.
Should I bother to try and normalize it?
Can it be Normalized?
Is it a pain?
Or should I just start over and create a new database. I thought about doing this but don't know if I can copy the old information into the new one.
Thanks for any advice you can offer.

I have data that I would like to use within another system. In order for this information to work as desired I will have to "de-normalize" my tables into a single record set.
Here is the issue, I have 40k+ records that have the majority of the data I need in a single table. I have directory path links to the photos related back to the primary key.
I need to merge these into a single line of information.
Example:(this is simply an example and not the true layout)
Tbl1
PKEY De1 De2 De3
123 North 15 Blue
124 North 28 Green
Tbl2
PKEY Path PhotoName
123 M:Photo 123(a).jpg
123 M:Photo 123(b).jpg
123 M:Photo 123(c).jpg
124 M:Photo 124(a).jpg
124 M:Photo 124(b).jpg
124 M:Photo 124(c).jpg
124 M:Photo 124(d).jpg
The desired end result would look like
PKEY De1 De2 De3 Photo1 Photo2
123 North 15 Blue M:Photo123(a).jpg M:123(b).jpg
...and so on until all photos for the record have been listed out.
Any suggestions? If a search topic similar to my issue could be recommended I would appreciate it greatly.

I have a table -
TableID
PartNum
PartName
InstallTime_Shop
InstallTime_Site
InstallTime_Cadd
InstallTime_Testing
InstallTime Is a set amount of estimated time per part. This Value would be used to estimate time needed to install a part.
Should InstallTime_ be in its own table?
If it is in it own table would it one to one?

This has been a nightmare all around. Because I can't get 40 licenses for Access I'm stuck doing transferspreadsheets every day, which has worked out mostly, but I'm reaching the absolute limits of my knowledge. I can't even think straight and need help with a solution.
Here is the table data I'm bringing in (in a simple way)
Editor Client ResearchHits HitsSent AltEditor Pruned Edited
J. Doe Coca Cola 1000 500
J. Doe Coca Cola J. Schmoe 200 100
This data is brought in from two imports of data (there is actually a date column too that I didn't include). Now, what I need to do is have it subtract the "Pruned" from the "ResearchHis" and the "Edited" from the "HitsSent" while only showing Coca Cola and J. Doe once... is this possible?
Thanks.

Just wondering if I'm missing an SQL trick for normalizing this data I inherited from an Excel spreadsheet.
Current data:
Code:
Case | Insp1 | Insp2 | Insp3 | Insp4 | Insp5 | Rnsp1 | Rnsp2 | Rnsp3 | Rnsp4 | Rnsp5
---------------------------------------------------------------------------------
1234 WEEDS TRASH CAR <null> <null> WEEDS CAR <null> <null> <null>
1235 TRASH <null> <null> <null> <null> TRASH <null> <null> <null> <null>
Normalized table:
Code:
Case | Violation | InspectionType
-----------------------------------
1234 WEEDS Initial
1234 TRASH Initial
1234 CAR Initial
1234 WEEDS Reinspect
1234 CAR Reinspect
1235 TRASH Initial
1235 TRASH Reinspect
Right now I'm having to do it with ten different queries (each with its own query behind it to massage the original data), one for each Excel field, and checking for blank entries before appending. And there's going to be about 50 Excel tabs to gather up... anything I'm missing besides the basic slog?

i would like to have a table where i can track price changes, however i don't want this to based on an inventory order.
i have a table which has the amount of hours to be charged. i then have another table which has the price per hour charged. the price keeps on changing. both tables have the date. tableHours has the date of occurance and TablePrice has the date when the price was last updated.
i need to know how to structure the TablePrice. currently it is set as BillableHourType, Rate, EffectiveDate. If this is correct, i don't know how to run a query.
i need to multiply Hour*Price, criteria: Effective Date must be most recent date as of Date of Occurance.
All Help will be appreciated.
I posted this post on the Microsoft site and i got no good responses, i am new to this site, but if it is a problem of reposting, please let me know. i will not do it again.
thanks,
sam

I am using a table a user created which is like:
Member ID (key field)
Visit Date
Dept 1
Expense Code1 (combo box E through I)
Dept 2
Expense Code2
This goes on through Department 20.
Now they want to know how many E's for one month. I am stumped on how to normalize this or if it is even possible! I thought maybe there is a way to search the table as if it were a spreadsheet doing a "countif" function??
Any replies much appreciated!

I'm trying to build a query that will normalize some graphical data along the x-axis. To do this I need all the peaks to be at the same point. I'll just talk in generic terms of FieldX and FieldY for the X and Y variables (resp)
In my mind the steps require me to
1) Determine FieldX at Max(FieldY)
2) Determine difference between FieldX and arbitrary normalization point (probably 100k)
3) Shift FieldX at all points to put Max(FieldY) over 100k (its a log scale so I'll be dividing)
Steps 2 and 3 are easy, but step 1 is giving me grief.
Ok, so I know how to find Max(FieldY), easy enough. Now how do I find FieldX? My first thought is a complex series of subqueries. At some point in the past, where I was smarter than I am today, I created a query that would do numerical integration. Looking back at the query I can't understand it, but I think the principle will be similar.

I am attempting to normalize an existing database. I've created the table structures necessary and now I'm designing a query that will update the new field in my primary table: "LabelBaseProduct" with the primary key from my new table: "tblBaseProduct" where the old field from my primary table: "tblLabels.BaseProduct" equals the description field from my new table: "tblBaseProduct.BaseProductDesc".
A visual of my tables:
tblLabels (Main table)
- LabelID
- BaseProduct (old field with text data)
- LabelBaseProduct (new field, needs to be updated with PK from tblBaseProduct)
tblBaseProduct (new table)
- BaseProductID (PK and FK to tblLabels)
- BaseProductDesc (Field that should be matched to tblLabels.BaseProduct)
I tried to design a query using design view of the query design and this is what I have:
Code:
UPDATE tblLabels, tblBaseProduct
SET tblLabels.LabelBaseProduct = [baseProductID]
WHERE (((tblLabels.BaseProduct)=[tblBaseProduct].[BaseProductDesc]));
When I attemted to run the query it told me that it was going to updated over a million records. I only have just short of 2k records in my database.

I have some data in an array that I need to normalize, remove duplicates, and import.
Original Table
Every record in the array has a person, all but a few have an address, most have a phone, and some have an email.
Person----- Address ----- Phone ----- Email
Tom ----- 10 A Ln ----- 789... ----- e@a
Sue ----- 20 B Ln ----- 256... ----- _____
Sam ----- 30 C Ln ----- _____ ----- _____
Dan ----- 40 D Ln ----- 478... ----- _____
Jan ----- 40 D Ln ----- 567... ----- e@d
Stu ----- 50 E Ln ----- _____ ----- _____
Syd ----- ______ ------ 224... ----- _____
New Data Structure
I want to group the data by HouseHold; which Address will serve to define for this import.
tblHouseHold
hhID
tblAddress
adrID, hhID, Address
tblPerson
prsID, hhID, Person
tblPhone
phnID, hhID, Phone
tblEmail
emlID, hhID, Email
I've been working on a procedure to step through the recordset and add the data one record at a time so I can get rid of the duplicates.
I've tried a few approaches, but this is where I'm at now.
Code:
Dim rs As DAO.Recordset
Dim rsHH As DAO.Recordset
Dim rsPhone As DAO.Recordset
Dim rsEmail As DAO.Recordset
Dim rsAddress As DAO.Recordset
Dim rsPerson As DAO.Recordset
Dim db As DAO.Database
Set db = CurrentDb
[Code] .....

Currently trying to build a database for customer management and order placement/tracking. Want to set a couple of rules so that if I for instance click yes of billing and shipping address the same that the database will automatically fill the shipping address with the data I inputted for the billing address in the same table.
The other issue I can see I'll run into is, I want to be able to select one of the company ID's (made up of a three letter abbreviation of the full company name) in the product ordering table and it will automatically fill in the rest of the customer data (phone, email, address etc) data into that form.

What I have is a database setup with multiple tables in which different areas of my DC can input information simultaneously into their respective tables. I then have another database linked to it for myself to have a live view of each updated record. I would like to see all the records of each table in 1 single table (possibly just sorted ascending by time). Each table has the same Field headings but may have different qtys of records. As I will then have it linked to an Excel table to VLOOKUP from it.
I have tried Union coding but always get Syntax Error etc.

I have 2 identical database in terms of structure but it differs in data.
Basically I would like to import data from subDatabase to mainDatabase and ensuring that there are no duplicate records.
I have used the "link to datasource method" through importing the tables to have the "updating" function.
However, this method also means that the records in mainDatabase are also imported over to subDatabase which I do not want.
Is there a method to ensure that the records are shared/update one way only? (i.e. import from subDatabase to mainDatabase and not main to sub?)

I'm using the MS Access 2010 ExportwithFormating action to export three tables to a single MS Excel 2010 workbook. The action overwrites the first excel worksheet each time instead of saving all three worksheets in a single excel workbook.
How can I export three tables into a single excel workbook.

I have created a table that acts as a header for my data and a second table that acts as line item data. What I need to do now is add a second child table that uses the line item data as its parent table and stores associated line items for each record. Is this possible?
This is a skeleton view of what I'm going for:
Master Table:
tlbAuditReportHeader
- AuditDate
- AuditArea
- Auditor
Sub Table:
tblDiscrepancy
- Discrepancy
- CorrectiveAction
- ActualCompletionDate
- VerifiedDate
- Notes
Sub table to Sub Table
tblFollowUp
- FollowUpDate
- AssignedTo
- SpokeWith
- EstimatedCompletionDate
- Notes
Sometimes tasks change hands or are pushed back depending on work load. It would be nice to be able to track something like this.

I am using calculated field as a data type in access 2010.
They are working fine.
However, I added a new field and now the final calc won't work.
I have Subtotal adding loads of fields together. Works fine.
Then I have a VATunit field which is a double integer, so enter 20 and my next field is VATTotal calculates the SubTotal + the VATunit by doing (Subtotal/100)*VATunit. This calculation is fine and gives me the correct amount.
The next field is a Total field. Which adds Subtotal and the VATTotal together. Howver, the Total is the same as Subtotal. It is not adding the VATTotal to it?

I have some experience doing 'Update Query' using two different tables but I'm having a hard time doing an 'Update Query' using 3 tables.
I have my source table TP05XY with the fields 'Mark' 'Date' 'UTM_Edig' and 'UTM_Ndig'. Mark and Date are my primary keys (they together uniquely ID each record). I have my Observations table with the fields 'Mark' 'Date' and 'Obs_ID'. The last table is Locations with 'Obs_ID' 'UTM_E' and 'UTM_N'.
I want to update my fields UTM_E and UTM_N from UTM_Edig and UTM_Ndig. However, to do so, I have to go from my TP05XY table, through Observations table to update Locations table. Table TP05XY is joined to Observations through 'Mark' and 'Date' and Observations table is linked to Locations through 'Obs_ID' field.
I have tried a few options without success ... anyone knows how to do it?
Thanks,
Josée

I have being playing with ms access but I really don't know much about it or databases in general.I have created a very simple database to gather twitter following/followers data for research purposes.One table (table01) has a field for the "boss" user (=the user who I gather data for), another field for "client" (=bosses followers or friends).Both fields are numeric and contain the users id's.In order to distinguish if the link is follower or friend there is a third field, called type which can be either 1 (=follower) or 2 (=friend).So the data would look like this:
boss - client - type
12345, 67890, 1
12345, 54321, 2
If user with user id 12345 had a follower (type 1) with user id 67890 and a friend with user id 54321...In order to avoid getting duplicate rows I also added a unique identifier which is of the form boss_id-user_id-type.So the above row looks like this:
12345-67890-1, 12345, 67890, 1
12345-54321-2, 12345, 54321, 2
That works just fine.For several reasons I also needed data of the form source - target.So I also made another table (table02) of this form.
67890, 12345
12345, 54321
...
In table 2 you don't need the "type" field since the position of the user id shows the type of relationship.Still, you need a unique identifier in order to avoid duplicates, so I added on with the form: source_id-client_id..So table02 lookes like this
67890-12345, 67890, 12345
12345-54321, 12345, 54321
...
Both tables also have a date/time stamp for each line.As you can see, table01, having also a type field is bigger than table02.The problem is when I try to append data, exactly the same data in both tables.Appending data to table01 is ok, while appending data to table02 (which is smaller, having one less field) takes a really long time, maybe 10 times as long as appending data to table01.To make sure that no query's are causing the problem I have tried first creating temporary tables with the data to be appended, no duplicates, nothing that would cause the database to make extra calculations and used a simple update query with no filters to append data.Still I get the same result, table02 takes a very long time to finish while table01 finishes in no time.

I am currently using Microsoft Access 2010 32bit, and have one database acting as parent, with a second linked database as a client for people to work with, and the parent database has tables imported from Sage V21 via ODBC. I have used the following code as specified in other examples as follows:
Code:
DoCmd.TransferDatabase acImport, "ODBC Database", "ODBC;DSN=MyDNSMachineName;UID=MyUID;PWD=MyPassword;LANGUAGE=us_english;" & "DATABASE=pubs", acTable, "INVOICE", "INVOICE"
one of the tables has 10k records in it, it only transfers 77 records. After manually attempting an import via the ODBC wizard it finally lets me access all 10k records.I wish to have a single button click delete and import fresh tables without worrying if all the data is coming across.Also, when manually adding a table, I am usually asked by the wizard to specify an index, but with the code above, I am not offered that option and the tables come across with no index. I am led to believe that having tables that link to each other without an index is bad, so how do I ensure an index is created?
