Using libraries
It is hard to predict the needs of a particular application, so
the organization of a target’s libraries generally evolves over the
development cycle. PowerBuilder lets you reorganize your libraries
easily at any time.
About library size
For small applications, you might use only one library, but for
larger applications, you should split the application into different
libraries.
There are no limits to how large libraries can be, but for
performance and convenience, you should follow these
guidelines:
-
Number of objects
It is a good idea not to have more than 50 or 60 objects
saved in a library. This is strictly for your convenience; the
number of objects does not affect performance. If you have many
objects in a library, list boxes that list library objects become
unmanageable and the System Tree and Library painter become more
difficult to use. -
Balance
Managing a large number of libraries with only a few objects
makes the library search path too long and can slow performance by
forcing PowerBuilder to look through many libraries to find an
object. Try to maintain a balance between the size and number of
libraries.
