In this paper, we survey some of the recent developments in application modeling and concurrency control in Active DBMS (ADBMS). We first review the evolution of Active DBMS and different application areas of ADBMSs. Application modeling techniques for ADBMS applications have been surveyed after that. Then we discuss about the execution modeling and concurrency control in active DBMS -- which is one of the most challenging areas in active database research. Several important active database research projects are also reviewed with mention of their contributions and current research directions pointed out by these projects.
