QOF, the Query Object Framework, provides a set of C Language
|
||
|
|
utilities for performing generic structured complex queries on a
|
||
|
|
set of data held by a set of C/C++ objects. This framework is unique
|
||
|
|
in that it does NOT require SQL or any database at all to perform
|
||
|
|
the query. Thus, it allows programmers to add query support to
|
||
|
|
their applications without having to hook into an SQL Database.
|
||
|
|
|
||
|
|
Typically, if you have an app, and you want to add the ability to
|
||
|
|
show a set of reports, you will need the ability to perform queries
|
||
|
|
in order to get the data you need to show a report. Of course, you
|
||
|
|
can always write a set of ad-hoc subroutines to return the data
|
||
|
|
that you need. But this kind of a programming style is not extensible:
|
||
|
|
just wait till you get a user who wants a slightly different report.
|
||
|
|
|
||
|
|
The idea behind QOF is to provide a generic framework so that any
|
||
|
|
query can be executed, including queries designed by the end-user.
|
||
|
|
Normally, this is possible only if you use a database that supports
|
||
|
|
SQL, and then only if you deeply embed the database into your
|
||
|
|
application. QOF provides simpler, more natural way to work with
|
||
|
|
objects.
