values, Interchanging Row and Column elements in a two dimensional array;

Relational data model: Concept of domain, tuple, relation, key, primary key, alternate key, candidate
key;
Relational algebra: Selection, Projection, Union and Cartesian product;

Language;
Data types: NUMBER/DECIMAL, CHARACTER/VARCHAR/VARCHAR2, DATE;
SQL commands:
CREATE TABLE, DROP TABLE, ALTER TABLE, UPDATE...SET..., INSERT, DELETE;
SELECT, DISTINCT, FROM, WHERE, IN, BETWEEN, GROUP BY, HAVING, ORDER BY;
SQL functions: SUM, AVG, COUNT, MAX and MIN;
Obtaining results (SELECT query) from 2 tables using equi-join, Cartesian Product and Union
Note: Implementation of the above mentioned commands could be done on any SQL supported
software on one or two tables.
