Hi! I am spending some hours designing a cach for our database. But now I am in doubt. Do we need a cach in our database? What do you think? I guess not, since it has rarely been a topic in this discussion group. On the other hand, the assignment says:'Note that the locking required is effectively a "write" lock only'. And it is fun to implement. But overdesigning is not rewarded I suppose. /Hugo
The only caching I have is on the client side. I needed a table model anyway to populate the JTable, so I'm using the table model as a place to store FieldInfo and DataInfo between searches. Of course, the cache will be out-of-date as soon as another client updates the database, so I need to re-read the database before doing any updates.
No need to design cach. It is efficient to query the database when you need them.

I mean server side to avoid locking overhead an disk access. The serverside cache is not locked for non-destructive methods, for reading there is no locking overhead at all. That would be the benefit. But the assignment does not stress this point. /Hugo.
