4 tables for the database: PATRON, BOOK_COPY, BOOK, and CHECKOUT. (Since a book may have multiple copies that may be purchased by the library at different time, it is better to have a BOOK_COPY table to avoid unnecessary data redundancy.) The data in the tables are as follows: PATRON table records a patron’s ID, name, address, phone number, and email address. BOOK table contains information such as author, title, publication date, subject, language, and a unique identifier (It can be the ISBN of the book) for each book. BOOK_COPY table records a unique identifier for each copy of a book, the date of purchase, and the identifier of the book from the BOOK table. CHECKOUT table records the date of check-out, patron’s ID, the identifier of the book copy from the BOOK_COPY table, and the due date.
For the below `bank' schema: customer(customerid,username,fname,lname,street1,street2,city,state,zip) account(accountid,customerid,description,) transaction(transactionid,trantimestamp,accountid,amount) A customer may have several accounts, and each account may participate in many transactions. Each transaction will have at least two records, one deducting amount from an account, and one adding amount to an account (for a single transactionid, the sum of amounts will equal zero). Using SQL, answer this question (write a SQL query that answers this questions): 5. What is the balance (total across all accounts) for customerid=42?

Implementation the example of stored procedure now creates the stored procedure which: Have an ability to insert the record in the table. Have an ability to delete the record in table. Have an ability to update the record in the table. Have an ability to display the record in the table.
as a database you need to ensure that each excercise log has a unique ID number, date, excercise category, excercise subcategory, time spent, calories burnt . each customer has unique cust_number and their first name, last name, address, program number, program tile and payment must be recorder. every program has a program number(PNum) that uniquely identifies the program. the program title, startDate, FinishDate, price must also be recorder. each coach has unique Id number. their first name, last name, date of birth, address, contactNo, username and password must be recorder. A coach can work on only one program. A program can have one or more coaches associate with it. one customer can enroll for one program at a time. normalize the above database in 3NF. State for every step in normalization which functional dependency cause it. identify different type of anomalies which can be found in a database. how can we overcome them ?
