The grid-based collaborative database model

In the collaborative grid environment, there are some characteristics of the database, such as polymorphism, self-made and distributed and so on. In general, the traditional database management system which takes information sharing as its core function cannot fully meet requirements. Therefore, it is necessary for us to establish a “collaborative management system of database”, that is, cooperative database model. This paper discusses the concept of cooperative database, establishes a collaborative database model based on MAS, and researches data query processing of cooperative database and data version management.
