The integration of functions  means not only the physical connections of hardware, but the data communication and data  sharing among sub-systems. The database is the heart of integration. To date researchers have  been unable to present a concrete data model and database architecture to support the CIM  system.  The problem undertaken in this study is to select the appropriate database models best  suitable to support all sub-systems of CIM. In this work, the database model is proposed based  on data analysis of the manufacturing system. From the data analysis, a CIM data model has been  developed which ultimately led to derive the database requirement for generic CIM systems. The  selection criteria for the CIM database is established from this database requirement. The  available database models are evaluated critically in the context of each and every selection·  criteria. Finally the database model is selected using multi-criteria technique Analytic Hierarchic  Process (AHP).  Finally the two closely and most compatible database models are implemented on Bill of  Materials (BOM) and Material Requirement Planning (MRP) modules to prove the superiority of  object-oriented database over relational database in the context of CIM systems. 0aComputer integrated manufacturing systems1 aBatanov, Dentcho N.,eChairperson1 aTabucanon, Mario T.,eExamination Committee1 aBohez, Erik L.J.,eExamination Committee2 aCanadian International Development Agency (CIDA)., eScholarship Donor2 aAsian Institute of Technology.tThesis ;vno.
