How to understand sql ddl and dml

Assignment Help PL-SQL Programming
Reference no: EM13335004

The objective of this assignment is to:

(1) enhance your understanding of Relational Database Design & Implementation using CASE tools (e.g. Rational Rose, or Power Designer), and

(2) understand SQL DDL and DML.

The assignment will consist of four (4) tasks.

x Task one will provide a relational database implementation of the sample solution from the first assignment. This should be done using CASE software (the choice will be up to you).

Sybase's Power designer? or Rational's Rational Rose? are both possible choices. Note, the diagrams cannot be hand-drawn. The diagram will be pasted into a document.

x Task two will be forward engineering the model to produce DDL (Data Definition Language) scripts. Alternatively you may choose to code the DDL's yourself (see previous practical examples). Make sure the primary keys and foreign keys are properly stated.

x Task three will involve the population of tables with sample records through insert table statements. Again the CASE tool may be able to help you here. Alternatively you may choose to write your own scripts (see previous practical examples).

x Task four will involve writing and executing SQL queries.
