Converting a mainframe database into Ms-Access using VB.NET

Pete OHanlon

So what exactly are you asking for? Somebody to decode the format for you? Somebody to write the conversion code? You need to be a lot clearer on what help you are after other than a vague "I'll send you some files".

As you advised, I have collected some more details about this inf*act db which are given below. Nielsen Inf*Act db is a SQL db compatible with relational Star schema Data model. We are receiving the inf*act db datasource from the client in a folder(the folder should be in country code) and this folder contain the files with the formats of .hed,.chr,.idx,.inf and .tad(5 files for each DB). If the datasource dump has 50 db means, the datasource folder will contain (50dbs*5files for each db) 250 files. We are adding each database through our tool by browsing the file in the format of (.hed ) from this datasource folder. One important thing is, if we delete any one of the file among those 5 files(.hed,.chr,.idx,.inf and .tad) for a db, the database will not get added in our report template tool. As i discussed here, the data is available in .inf file. First i have to extract the data from this file. Then only i can import them into ms-access. So, i want the code in vb.net, that how to extract the data from this file and import them in ms-access. I think this will help you a lot :) Thanks, Sivakumar.M

You'll need to write it - this isn't a drive-through :) First, you'll need to determine the layout of the .inf file, and create a means of reading it into VB. If you need help, you can post an example of the contents of the .inf file here. Writing the data to an Access database would be the second step. Good luck :)

Nope. I'm not writing your code for you - that's your job. This isn't rentacoder where you get some dumbnut to write code for you, and I don't get paid to do your job for you. Tell you what, put me in touch with your client, and my company will do the work for them directly - we'll even throw in a support contract for them.

Ask the client whether any kind of connection is available to access the database. If there are none, ask them to export the content of database to certain format (CSV, XML, flat files) If they can't, ask the client if it is a known database that your team can understand if you need to get down and dirty to decode the database If it is not a known database format, ask if they got documentation on the database structures. If they can't or no document, tell your PM your team is in deep shit..
