Alzabo is a program and a module, with two core functions. Its first use is as a data modelling tool. Through either a schema creation interface or a perl program, you can create a set of schema, table, column, etc. objects to represent your data model. Alzabo is also capable of reverse engineering your data model from an existing system. Its second function is as an RDBMS to object mapping system. Once you have created a schema, you can use the Alzabo::Runtime::Table and Alzabo::Runtime::Row classes to access its data. These classes offer a high level interface to common operations such as SQL SELECT, INSERT, DELETE, and UPDATE commands. This release is mostly bug fixes with a few new features. Upgrading is recommended because some of the bugs can be annoying though none are catastrophic Changes: 0.33 - The linking table methods generated by Alzabo::MethodMaker were broken. Fixed this. - Changed how order by clauses can be passed to select operations. Also changed the docs, which were way out of sync with the changes in this area. - Attempting to update more than one value at once was broken. Fixed this. - Added Alzabo::Runtime::Table->func method to allow arbitrary column aggregate functions like MAX, MIN, AVG, etc. - Fixed schema creator bug. It was not possible to change a column's NULLability after it was created. - When changing a column's type, Alzabo now removes any column attributes that are not valid for that column. In addition, if the existing length and precision parameters are not valid, they will be set to undef. - Fixed the code to get rid of weird error messages that came from DBI with Perl 5.6.0+ when the Alzabo::Create::Schema->create or Alzabo::Create::Schema->reverse_engineer methods were called. For the curious, this has to do with the DBI object passing through Storable::dclone.
