Normalising Data

Hi All,

I am building a database (Access 2003) and have a table containing around 100,000 rows of data.

Each row has four data points; ID, Name, Month Name and Total Sales.

Each ID can have up to 12 months of data... i.e. 12 rows.

I need to create one row per ID so that the table looks like this:
ID, Person Name, Month 1 Name, Month 1 Total Sales, Month 2 Name, Month 2 Total Sales, Month 3 Name, Month 3 Total Sales... etc.

Not everyone will have all months, so I cannot have a "Jan", "Feb" columns etc. Hence the reason for keeping the month name in the data.

I will need to sort the data so the earliest month comes after the person name.

Any ideas on how to do this within Access?

Thank you very much for your help.

MAX finds the largest value. =LARGE(A:A,2) will find the second largest. =SMALL(A:A,3) will find the third smallest

Hi Ivan,

Just to clarify -- the data is normalised at the moment. What you want to do is produce a query or report from that data; I would recommend a crosstab query.

If you have not built a crosstab before use the wizard.
1. Put ID and Person Name in the Row headings (first screen of the wizard).
2. Put sales month in the Column headings section (second screen).
3. Put Sales Total in the Value section (third screen) and change the summary function to Sum.

That should get you started. It can be tweaked further or used as the basis for a report; report back once you get to that point.

Thanks very much Denis. Thanks for correcting me. I will try a cross tab query.

Best regards,

Hi Denis,

The cross tab will work, but the problem that I have is that the month name is an actual date (that I need to preserve) and I thought I would get away with converting it to the month. But in hinde sight, it won't work. Apologies, I should have checked this before I started this task as I don't want to waste anyone's time.

Unfortunately, the cross-tab now has far too many columns and therefore won't run. To complicate things, some IDs won't have 12 records so what I thought is that instead of having it by month at the top, I could have 24 columns across (these being the date (1a) and the sales amount (1b) for each month) with the LATEST record date in columns 1a and 1b - for each ID.

The problem is that for each person/ID I need to give each record a "Record Number per ID"... so if one person has 6 dates and amounts, each of his/her records would have a progressive 1 though 6 identifier against each of the records. With the latest being number 1. I can then use this in the cross-tab.

I hope I haven't confused you. Thanks for all your help.

Re: De-normalising Data - DCOUNT

Hi,

I have tried to use the DCount function, but I cannot get it right. This is what I have, but it doesn't work:

Code: 
DCount ("[Date]", "tblDataset", "[PersonID]")

I am trying to calculate (In Access 2003) the "CountOfRecordPerID" data as per the example below:

<TABLE style="WIDTH: 198pt; BORDER-COLLAPSE: collapse" border=0 cellSpacing=0 cellPadding=0 width=264 x:str><COLGROUP><COL style="WIDTH: 48pt" width=64><COL style="WIDTH: 53pt; mso-width-source: userset; mso-width-alt: 2596" width=71><COL style="WIDTH: 97pt; mso-width-source: userset; mso-width-alt: 4717" width=129><TBODY><TR style="HEIGHT: 12.75pt" height=17><TD style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; WIDTH: 48pt; HEIGHT: 12.75pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" height=17 width=64>PersonID</TD><TD style="BORDER-BOTTOM: #ece9d8; BORDER-LEFT: #ece9d8; BACKGROUND-COLOR: transparent; WIDTH: 53pt; BORDER-TOP: #ece9d8; BORDER-RIGHT: #ece9d8" width=71>

Please could someone kindly give me a hand. Thanks very much.

Re: De-normalising Data - DCOUNT

How is it not working and why are you using DCount?

You should be able to do the count with a standard query.

What is it you actually want to count and how do you want to group?

Try adding the ID twice grouping by the first one you add and counting the second one.

Something like this psuedo query.

SELECT [PersonID], [Date], Count([PersonID]) As CountOfPersonID
FROM tblDataSet
GROUP BY [PersonID], [Date]

You can easliy set that up yourself in query design view.

Just add the ID field twice like I said, goto View>Totals and select the appropriate otpions (Group By, Count etc) from the dropdowns for each field.

By the way, what do you mean by 'preserve' the dates?

You can do just about anything you want with a field using and expression in a query and it won't affect the value in the table.

That is providing it's not an update/delete query.

So you should be able to group by month, and use months instead of dates in the column headers for the crosstab.

In fact I'm surprised the crosstab wizard didn't do that for you automatically.

Hi Norie,

Thank you for helping me. I must first apologise to everyone as I have been trying to do this for so long that can't see the wood for the trees and am making stupid mistakes. The table above is incorrect, but this post shows the complete correct request.

I have created the grouped count query as you said, but because I am grouping on both PersonID and Date, it is counting each one once (as I would expect), as below:

To get to table 3 above, I tried using a cross-tab query to get the result, but because I put a date field in the Column Heading, I got an error as there are too many dates.

So I thought that as each PersonID can only hold up to a maximum of 12 records, that I could count each of the records against each PersonID and then do a cross-tab query and put THIS count in the Column Headings. Effectively, that would mean 24 columns across (plus the initial PersonID field) with the latest dated record in "Data Point 1". Table 3 above illustrates this.

However, where I am stuck is that I do not know how to do the count, as per Table 4 below. I thought a DCount would be the best solution, but now, I just have no idea!

Once I have this "CountOfRecordPerID", I can then put it into a cross-tab query and it should do exactly what I need.

I hope I have explained it so that you will be able to understand it.

By the way, when I said 'preserve the dates' I meant that I need to use the dates and not convert it to just a month name.

Thanks again for your help.

I can't see how you can do what you want, basically because of the too many columns thing.

How would you analyse/display data with so many columns anyway?

By 'progressively' counting the number of records for each PersonID, I can then use that result in a cross-tab query to effectively get rid of all the columns.
