Data Managers 
Data Managers (DMs) are an interface to various data objects used within vBulletin. They enforce necessary constraints and administrator-set options on the data to ensure that the data is valid.

Data managers allow rapid integration of vBulletin-specific data structures and data constraints into additional code (such as used with the product manager) or third-party applications. With only a few lines of code, you can use the data managers to create new threads and posts, users, and more.

As of this writing, vBulletin has the following data managers:This list may be expanded in future versions.
