Relational Model (Logical and Physical Schema Development) The conceptual model developed in phase 2 will be transformed into a logical and physical schema using the relational data model. The outcome of this transformation will be a relational schema. The schema should have the following components: Set of required relations All the integrity constraints Submission and Evaluation: A report consisting of the problem statement, ER diagram, relational schema And implement the database using SQL should include: All the tables properly defined /created All constraints properly defined For each table, few instances of data should be entered.

DATABASE MANAGEMENT Design an EER diagram for a database used to manage a racket sport association (for example, US Tennis Association). The following is a list of simplified requirements. Each member of the sport association has an id, a name, sex, age, an address, a phone number. A member can be a player, an umpire (i.e., referee), a coach, or an officer (i.e. a member can belong to one or more of the above categories). An umpire has a type (i.e., national, international, etc.). A coach has a certificate (i.e., level I, II, etc.). An officer has an office (i.e., a room number such as 101 or 212 in the main building). Each club has a name, an address, an owner, and a phone number. Except for some officers, every member belongs to one or more clubs (Hint: Make relationships between the subclasses of “member” and club). A player can be a professional or an amateur (but not both). A professional player has a rank (such as 1, 2, etc. within the association), and a coach (Note: Every…

//Need typed version please You are working with a database that stores information about suppliers, parts and projects. The Supply relation records instances of a Supplier supplying a Part for a Project. The schema for the database used in this question is as follows: ( primary keys are shown underlined, foreign keys in bold). SUPPLIER (SNo, SupplierName, City) PART (PNo, PartName, Weight) PROJECT (JobNo, JobName, StartYear, Country) SUPPLY (SNo, PNo, JobNo, Quantity) Provide relational algebra (NOT SQL) queries to find the following information. NOTE: You can use the symbols s, P, etc or the words ‘PROJECT’, ‘RESTRICT’ etc . do not need to try to make efficient queries – just correct ones. Where you use a join, always show the join condition. List the name of any part that was not used on a project that commenced in 2020. List the name of any part that has been supplied to all projects that commenced in 2020.
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.
