The TAC Energy Client uses a database to store all data that comes in from the TAC Energy server. For your convenience database tables are automatically mapped to java domain classes by means of GORM object relational mapping. Read the section on database mapping in the grails user guide to understand the concept of object relational mapping and how to use this powerful technology for the development of your trading agent.

Also you should read the reference documentation on Domain Classes in order to understand the function, meanings and properties of each of the TAC Energy specific domain classes.
