The database schema published by Sage is referred to as the Application Object Model. The AOM illustrates the structure and framework of the tables and views for a Sage database.
This information can be helpful for importing and exporting functions, building integrations into Sage from other software, or doing data manipulation or repair. The AOM for the three current Sage versions is accessible by clicking on the attachments provided.
Extract or unzip the file and click on the Advantage.xml file. (note that the AOM works best in Internet Explorer). From this screen, select the module, and click into it. From here you have the ability to look at views, tables, or objects. For each, fields are identified along with the type of data required and (in some cases) lists of the values expected in that field.
