MWB - MySQL Workbench Document
This is a database document generated by MySQL Workbench which is a graphical interface used to administer and create MySQL database files. It can contain a database design which is called an EER (Enhanced Entity-Relationship) model and can define table views, privileges, routines and other constructs necessary for a database. These files are used to save the working progress of databases while they are being developed. When the EER model is finished, MySQL Workbench can then generate a full MySQL database from data in the MWB file.
