ExtZSQL provides SQL methods from the filesystem. It is mainly aimed at Python product developers, as it solves several problems associated with using SQL in filesystem products:

• Changing the statement requires refreshing the product.
• Changing the statement also requires re-instantiating all objects of that product.
• New SQL objects (ZSQL methods) must be created for each object. Imagine if you have lots of statements and lots of objects.
• You must re-initialize all statements to change the connection.
• You must keep SQL in your Python source, and sometimes in multiple places.

ExtZSQL solves this by providing a handy factory and a ZSQL-dervived class that gets its statement from the filesystem. It also provides a through-the-web type for using filesystem resident SQL files. (This is somewhat like the CMF FSZSQLMethod.)
