In a program, in which many forms access the same access database, which is better:
a) Opening the database once globally and each form opens a different recordset (unless a global one is required)
b) Opening the database on each form, but declaring it a different variable name?
Can i have pro's and cons of both thanks?
Cheers
Hi But_Why
If Many Forms are using the same database all of the time, it is best to open The database globally and close it when the app terminates. This is because if you keep on opening and closing the connection all the time it can slow down both your app and the database itself for other users. When making connections it takes quite alot of recources to open them. The only con to this is that if you are using a small RDBMS like access, if you have a lot of of active connection running at the same time it can also slow down the database.
Hope this helps

There is overhead associated with opening a database (time and memory). To open a database more than once is wasteful of both.
Thats what i thought as well, but there are some that think otherwise and i thought i'd get an outside opinion.
Thanks
