Denormalize a database

Hi,

I am working on a prototype which aims at predicting future soccer game results. I have found an app online which does the same thing. I want to use the database which the application is using, and I have the database as it came in the install package. All the tables are in separate files, and the database is no denormalized and column names are in french.

I need to denormalize the access database, get it all into one database, and know which columns are for which attributes so I can use that information in my prototype.

My question is - Is there a way to automatically denormalize a database in Access? Or using any other tool??

Also, is there a way I can find the code behind the actual exe?

The application I am using which also contains the database is attached statfoot32sha.exe

None that I can imagine.  Nor have I seen any such tool.  I would say you are in for a manual process, sorry.

1. The extensions of the files is .dbf.
This indicates that these are Dbase tables.
This means that you should be able to import these tables into an Access datebase and establish the relationships, and (in theory, at least) it should wok fine.
(Then translate the text as needed)

2. Thus I see no reason to "denormalize" this structure down to a single table (Flat-File).
(Why denormalize a fully functioning database?)

Finally,...Legally you may not even be allowed to do this.
This is a "packaged application" that is for sale and has a Licensing agreement.
And althoght I saw nothing that explictly prohibits you from "Using" this design in your own database, you should contact them directly and ask for permission before proceding.

I think there has been a confusion here. What I want to do is just use the stats for EPL from the given database, and once I have those stats I will import them in excel to get a csv file, and from there  import them in WEKA to get a good classifier for future predictions.

I am not looking to make any software or copy their design, I am just trying to apply data mining techniques using naives bayes and others to find future results for the outcomes of these games.

There are other sources online as well through which I can get data for each game, but in that case I would have to scrape the data and write up a lot of code to do that. Instead I can just use some queries to get the data I need from this database.

  As MX said, no, it's a manual operation, for which you'd simply use a query to "flatten" the data and then an outputto command or VBA to get it into some other format.
