Transaction Processing

Transaction processing is a computational style generally performed by server computers, which supports interactive applications (apps). Transaction processing is also known as information processing, which divides the work into indivisible and individual operations called transactions. The transaction is a set of tasks; a single task is considered as the minimum processing unit that cannot be divided again.

Part Design a database for an Access Control System. The purpose of the system is to control who has access to which doors at what time. There are six entities in this database: ● ● Users Groups O A user can be assigned to more than one group. Doors AccessRules O Decides which Group has access to which Door at which TimeSchedule. Example: Group A can access the Front Door on Monday from 7am to 9pm. o o Example: Group B can access the Back Door on Saturday from 8am to 10pm. TimeSchedules To make it simple, we only need to pport Weekly Schedules. The TimeSchedules table has the following columns: Id O O DayOfWeek StartTime ■ EndTime o Example: a schedule with DayOfWeek-Monday, StartTime=7:00, EndTime=23:00 means this schedule grants access on Monday from 7am to 11pm. Entrance Logs O This table keeps a permanent record of which user accessed which door at what time. o The logs must remain valid even after the related records have been updated.

A taxi company would like to provide an online service for customers to book a trip and for taxi drivers to check their upcoming trips. A database needs to be created to store customer data (name, address, email, telephone number) and trip information (pick up and drop off address and pick up time and date). Furthermore, your database should contain driver information (name and license plate). Each trip must be assigned to exactly one driver (and trips for a driver must not overlap). Customers who are not registered yet need to register (providing their address, phone number, email address, and credit card information). A registered customer should be able to book a trip, i.e. provide the pick-up address and time as well as the drop-off address via a graphical user interface. Customers should also be able to view their trips and cancel them if needed. All these operations are only possible after a customer signs in (which means they must be registered). Each new trip must be confirmed…
