| A Database System(DBS) consists of a Database | |
| Management System(DBMS),Database(DB) and | |
| application programs.Relational model(RDBMS) | |
| is mostly widely used data model. Relational model organises data into a | |
| number of relations. | |
| A relation is defined by attributes.Relation is a set of tuples of values related according to the attributes. | |
| Relations can be thought about as tables with attributes being columns and tuples being rows of values. | |
| Relational data model builds on top of set theory and relational algebra. | |
| Tables can be related together by the use of primary and foreign keys. | |
| Relational model supports a standard Structured Query Language(SQL). |

| SQL has one basic statement for retrieving information from a database: the | |
| SELECT statement. The structure of select is as follows: SELECT [DISTINCT] c1,c2 FROM table WHERE condition | |
| GROUP BY column_name HAVING condition ORDER BY column ASC | DESC. | |
| SELECT lists the data items to be retrieved, it might simply be columns from the database, | |
| or result of calculation on columns, results of functions such as MIN, MAX, AVG, SUM, COUNT,Abs, Ceil, etc. | |
| Asterisk * can be used to select all columns. Items might also be given aliases with AS clause. | |
| Since SQL table is a multiset rather than set, DISTINCT can be specified to ensure that the result table only has distinct rows. | |
| FROM specifies the table from which data is to be retrieved, | |
| this can be a JOIN ed table. WHERE search condition is applied to every row one by one. | |
| If it returns TRUE, row get added in the result. Conditions can be comparison tests(=,<>,>,<,etc), |
