In this paper, a semantic based multi-granular lock model for object-oriented database systems is proposed. It addresses the concurrency control issues related to all types of transactions to an object: run time transactions and design time transactions. In the case of run time transactions, it ensures consistency while providing fine granularity. In the case of design time transactions, the proposed work has the following features: First, it provides separate lock modes for all types of design time operations. Second, it provides fine granularity for design time transactions. Third, it reduces deadlocks due to lock escalation. The proposed work shows how concurrency can be maximized while ensuring consistency for all types of transactions. A simulation model is constructed to evaluate the performance of the proposed work. This model is used to compare the proposed work with two existing techniques. The performance results show that proposed scheme is better than existing works.
