Concurrency Control

The simultaneous occurrence of two or more operations is called concurrence and the situation is called concurrency. In concurrency, the function of one operation can affect the function of the other and put data integrity at risk. Hence, management for the control of concurrency is required. The management or controlling system in the Database Management System (DBMS) that coordinates concurrent access is called the concurrency control system.

For a long time, the Royal Victoria Hospital (RVH) worked with an information system that consisted of a mix of paper-based files and small independent databases developed within some departments. The new administration created an information system (IS) department and hired you as information officer: head of the team in charge of the design and implementation of a new global information system. The first team from the IS department conducted interviews with some hospital administration and staff to identify entity types for the hospital. The following information was collected by this team. The hospital depends primarily on four groups of people: employees, physicians, patients, and volunteers. Of course, some common attributes are shared by all these groups: person_ID (identifier), name, address, birth date, and phone number. Each group also has at least one unique attribute of its own. Employees have a date…
