I have a database that increases every month. The schema remains the same, so I think I use one of these two methods:

  • Use only one table, new data will be appended to this table, and will be identified by a date column. The increasing data every month is about 20,000 rows, but in long term, I think this should be problem to search and analyze this data

  • create dynamically one table per month, the table name will indicate which data it contains (for example, Usage-20101125), this will force us to use dynamic SQL, but in long term, it seems fine.

I must confess that I have no experiences about designing this kind of database. Which one should I use in real world?

Thank you so much

    20 000 rows per month is not a lot. Go with your first option. You didn’t mention which database you’ll be using, but SQL Server, Oracle, Sybase and PostgreSQL, to name just a few, can handle millions of rows comfortably.

    You will need to investigate a proper maintenance plan, including indexing and statistics, but that will come with lots of reading and experience.
