Indexed (Keyed) Data in .NET?

[hhinman]

I'm looking for a technique to allow a data file to be accessed by one or more keys without having to use a database. This is known in other languages as ISAM or VSAM (IBM Mainframe) access. The application needs to store persistent data on disk that be retrieved by one or more fields (keys). Are there any XML classes that support such, for example?
Thanks,
-Howard

XML makes a very poor database for anything over a couple hundred records.

You might want to do a search on sourceforge.net to see if someone has created a flat-file database system. But with the easy use of MS-Access and MSDE, I sort of doubt that anyone has, other than as a purely academic exercise.

Well, I don't consider it to be academic to pre-req a simple application with a database system like MS-ACCESS or MSDE - it adds to complexity for users as well as software requirements and adds a level of configuration management to over complicate things as well. I think somebody missed the boat if there is not a simple indexed flat file system available.....

I agree with hhinman, if you are processing every row in a table there should be a way to put the table to a flat file process it and put it back. Saves a lot of IO and CPU.

Well guys, sounds like you've identified a need.
Why not start your own sourceforge.net project to write one?
