Considering the un-normalized relational table PROJECT below: PROJECT (ProjectTitle, EmpeName, ManagerName, Location, HoursWork, ManagerPhone) The attributes of PROJECT table satisfy the following properties: Each project has many employees, Each employee may involve in one or more projects, Projects are managed by managers; there are many managers in the company, hence a project may be assigned to any one of the managers, but each manager manages only one project. Each project is located in a specific location, The number of hours an employee works at each project is determined by a project title and the name of an employee. Each manager has a telephone number. Normalize the relational table PROJECT into a minimal number of relational tables in BCNF. Use the functional dependencies to prove that each one of the relational tables obtained from the decomposition of the original table is in BCNF.

A Bank has many customers. Attribute for customer includes customer number, name, address (street, city, state and zip code), sex and date of birth. Customer can have multiple accounts. The bank does not allow join account (one account per customer). Type of account offer by the bank are Saving, Current and Fixed Deposit. Attribute for account are account no, account type, and account balance. Each of the account can only exist in a particular branch. Attribute for branch are branch no, branch name and address (street, city, state and zip code). Customer can open different account at different branch. Draw an ER diagram for the above situation. Identify the entity, attributes, primary key, relationship and multiplicity constraint in the ER diagram.
Using the company schema, when creating the "works_on" table, the foreign key should be specified as: foreign key (pno) foreign key (essn) foreign key (essn, pno) references employee (ssn) and project(pnumber) foreign key (essn) references employee(ssn), foreign key (pno) references project(pnumber)
