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.

An E-learning website needs your help to design its database. They need to store information about teachers and online tutorials. Each teacher has a unique ID, name, and at least one field of specialty. Teachers form groups to prepare online tutorials. Each group has unique name and at least one teacher as a member. Each online tutorial has a title, date and organized by exactly one group. The title of the tutorial is unique for the group. Each tutorial consists of several sessions, described by their titles and durations. Naturally, each session is presented by one teacher and belongs to exactly one tutorial. In addition, sessions on the same tutorial have different titles. Design an ERD for this application. Note any unspecified requirements, and make appropriate assumptions to make the specification complete.

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…
