For doing data validity testing you should be good in SQL queries For data integrity testing you should know about referential integrity and different constraint. For performance related things you should have idea about the table structure and design. ... IF the database schema is 3rd normal form, then that should be maintained. Check to see ...

3 rd Normal Form (3 N.F) : A relation is said to be in 3 NF is and only if it is in 2 NF and every non key attribute is non transitively dependent on the primary key. This normal form avoids the transitive dependencies on the primary key. Boyce code Normal Form (BCNF) : This is a stronger definition than that of NF.

Data Preserved in Third Normal Form . In order to speed queries, several new data warehouse query tools require that the data warehouse be denormalized from 3rd normal form. Adding redundancy can increase the size of the data warehouse and can also add to the complexity of the Data Base AdministratorÕs (DBA) task.

3rd Normal Form (3NF) A table is in 3NF if it is in 2NF and if it has no transitive dependencies. Boyce-Codd Normal Form (BCNF) A table is in BCNF if it is in 3NF and if every determinant is a candidate key. 4th Normal Form (4NF) A table is in 4NF if it is in BCNF and if it has no multi-valued dependencies. 5th Normal Form (5NF)
Information Processes and Technology Specifications
Databases represented in 3rd Normal Form do not have any integrity issues because their structure prevents redundant data being stored. SQL Syntax Structured Query Language (SQL) is a language used to access and manipulate data in relational databases. For the IPT course, the following syntax is to be used: SELECT (what is to be displayed)
