From ADOdb Version 5.21, A new method of managing changes to the schema has been added. This method is called Structured schema management to signify the more formal method of managing elements. The original method, referred to as Simple, remains unchanged.

In Structured schema management, the elements that can be modified through the dictionary management routines such as createIndexSql(),dropSql() and createtableSql() can be created and represented as objects prior to them being passed to the methods that create the SQL necessary to create them in the database. The concept is built on AXMLS and contains some feature overlap.

These objects can then be easily stored through the use of technologies such as JSON, which can easily be manipulated through 3rd party tools and reprocessed.
