DBIx::Objects Description

DBIx::Objects is a Perl extension to ease creation of database-bound objects. DBIx::Objects is a Perl extension to ease creation of database-bound objects.SYNOPSISThis module is intended to provide an object-oriented framework for accessing data sources. The source of the data is completely abstract, allowing for complete flexibility for the data back-end. This module is NOT intended to provide a persistance layer - please use another module (like TANGRAMS) if you require object persistance.I'm really not sure how to go about documenting this library, so let me start by explaining the history of why it was writtenBACKGROUNDI developed this module when I began to notice that most of my web-applications followed a very similar format - there was a data back end and web methods which could interoperate with them. When I started to need helper applications to work with the web-apps, I started porting all of my applications to use 2 layers. The lower layer was an object framework which contained the Perl code needed to work with the database. This way, I could be sure that all of the helper applications, and of course the web application, all used the same access methods to get to the database to eleminate the possibility that something was getting f#$ up in the database by a faulty query somewhere in the big mess of code. (The upper layer was the "business logic" layer, which was the web or helper application.)Then, I noticed that all of these database access objects were very similar: they all had access methods for each member of the class, which represented a single field in the database and had select/insert/update/delete routines.I'd also developed a "dynamic object" at this point, where I'd have a huge variable-length field in the database which conatained many fields. This way I could change the object without worrying about compatibility in the back end database if I added/changed/removed fields. (We'll get back to this later.)Beyond that, there were different ways of embedding objects (for example, a person object might have a phone number object embedded in it as part of an address-book application). (We'll get back to this later, too).So there were different ways of logically grouping different sets of data, but the objects all shared a unified way of accessing the data. Thus was DBIx::Objects born - it provided a framework which would reallly guarantee that the objects would really function in a logically similar way - similar to the way that most GUI applications work in logically similar ways (they all have that File menu with Open , Save, Exit... The Help menu with Help topics, an optional upgrade, etc). So I guess you could call this library an API for developing database bound objects. Requirements: · Perl
