sql queries | Computer Science homework help

  The data manipulation language (DML) is used to create, read, update, and delete data from a table. The data definition language (DDL) is used to create and alter the structure of the database itself, like creating a table, it’s columns, define and modify the primary and foreign keys, stored procedures, delete columns, tables, and even the entire database. Your SQL statements should require a variety of SQL capabilities, such as various kinds of join, aggregate functions, etc. (This presupposes a good initial domain choice.) 

Follow these steps to complete your assignment:

  1. Populate your database with sample data to allow testing of the schema and the various transactions. Each table should have a minimum of ten rows.
  2. After you’ve entered data, create some sample queries to see if the output is what you expected.
  3. Create some sample reports to make sure these also produce similar results.
  4. Make any necessary corrections to the database design during this stage and before you enter all of your personal records. If you find any problems, correct the design. 
  5. Enter all of your personal records.
  6. Write your SQL Script.
