The twelfth overseas convention on Database platforms for complex purposes (DASFAA), prepared together by means of the Asian Institute of know-how, nationwide Electronics and desktop expertise heart and Sirindhorn overseas Institute of expertise, sought to supply info to clients and practitioners of database and database structures on complex purposes. The DASFAA convention sequence has already validated itself and it keeps to draw, every year, individuals from around the world. during this context, it can be recalled that the former DASFAA meetings have been effectively held in Seoul, Korea (1989), Tokyo, Japan (1991), Daejeon, Korea (1993), Singapore (1995), Melbourne, Australia (1997), Taiwan, ROC (1999), Hong Kong (2001), Kyoto, Japan (2003), Jeju Island, Korea (2004), Beijing, China (2005) and Singapore (2006). Thailand had the chance to host this prestigious and critical foreign convention and subscribe to the league. This convention offers a world discussion board for educational exchanges and technical discussions between researchers, builders and clients of databases from academia, company and undefined. DASFAA makes a speciality of study in database conception, improvement of complex DBMS applied sciences and their complicated functions. It additionally promotes learn and improvement actions within the box of databases between contributors and their associations from Pacific Asia and the remainder of the area .

The number of attributes per dimension, other than those included in the primary key, ranges from 1 to 10. The exact number of attributes per dimension and the attribute type is chosen at random. We deﬁne an index for every primary key. We randomly deﬁne two sets of 9 star join queries, Q20 and Q50 , one for each database schema. Each set contains queries involving 20 and 50 relations, respectively. Every query includes all the relations of its corresponding database schema with at least one explicit join condition associated with each relation.

Suppose r j is an instance from ext(R j ), and let Join(·) denote the event that instances are joinable. ri )) · Pr(Join(ri , rh )). |Ri | Pr(Join(ri , rh )) ≈ N |Rh |·|Ri+1 | . So the estimated answer size of (R1 →R2 ∧ . . |Ri+1 | = .
