Tracking Database Create two tables based on the E-R model shown the below; and the business rules in the following list for a work order tracking database. Include all constraints in the CREATE TABLE statements. You should have only two CREATE TABLE statements and no ALTER TABLE statements. Name all constraints except NOT NULLS. Use your judgment for column data types and sizes. Project number and work number are used to uniquely identify roles in the tables. Each project added must be assigned a name and no duplicate project names are allowed. Each work order must be assigned a valid project when added and be assigned a description and number of hours. Each work order added must have a different description. The number of hours assigned to a work order should be greater than zero. If data is provided for the Wo_complete column, only "Y" or "N" are acceptable values. INSTRUCTIONS Create and execute the SQL statements needed to enforce the data relationships among the tables. In a word document, copy the SQL statements as well as the Oracle spooled output results. Be sure to insert proper subheadings identifying each section (i.e. SQL statements, Oracle spooled output results, etc.). In order to complete this assignment please follow these guidel
