Dynamic datastructure of objects

P: 1

I would like to disccuss with the following issue:
We want to create database in which we can dynamically add attributes.
The problem is, we do not know the datastructure before. The datastructure has to be defined in some metadata structure.


My suggestion:

If I do it this way then I cannot imagine, how the response time of SQL statements will look like...

The DATA Tables should have more then 50.000.000 records!

Do you have another idea or experince?

Thank you,


PS: I hope you can understand my problem...
