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.

Consider a PUBLICATION COMPANY database in which data requirements are summarized as follows: Every topic should contain name, code and research area. The topics can have several reports and the reports may contain several topics in them. The report should have a title. A department can publish more than one report. A report can be published only by a single department. The department must have its name and address. Reports can be written by many contractors and contractors can write many reports.

Q3. Suppose you are given the following business rules to form the basis for a database design. The database must enable the manager of a company dinner club to mail invitations to the club's members, to plan the meals, to keep track of who attends the dinners, and so on. Each dinner serves many members, and each member may attend many dinners. A member receives many invitations, and each invitation is mailed to many members. A dinner is based on a single entree, but an entree may be used as the basis for many dinners. For example, a dinner may be composed of a fish entree, rice, and corn. Or the dinner may be composed of a fish entree, a baked potato, and string beans. Because the manager is not a database expert, the first attempt at creating the database uses the structure shown in the table below: Attribute Name MEMBER_NUM MEMBER_NAME MEMBER_ADDRESS MEMBER_CITY MEMBER_ZIPCODE INVITE_NUM INVITE_DATE ACCEPT_DATE DINNER_DATE DINNER_ATTENDED DINNER_CODE DINNER_DESCRIPTION Sample Value…
