From the software development methodologies described in the article titled, "Process-centered Review of Object Oriented Software
Development Methodologies," complete the following.
Evaluate which method would be efficient for planning proactive concurrency control methods and lock granularities. Assess how your selected method can be used to minimize the database security risks that may occur within a multiuser environment.
Analyze how the verify method can be used to plan out system effectively and ensure that the number of transactions do not produce record-level locking while the database is in operation.
