IPL DATABASE

OBJECTIVE

To understand the main concept of data base management system and what data base is all

about.

To exhibit how data’s are been categorized in IPL using data base management system.

INTRODUCTION TO DBMS Data base is a vital part of any organization.

It needs to be stored, organized, managed, accessed, protected and manipulated.

The database is used to keep track of things unlike a list or spreadsheet, a database may store information that is more complicated than a simple list.

PURPOSE OF DATABASE

In early days, database applications were built on top of file systems.

The difficulties faced in file system was that,

• Multiple file format• Duplication of information in different files• Integrity problems• Atomicity of updates• Security problems

TYPES OF DATABASE

Operational database End – User database Centralized database Distributed database Personal database Commercial database

APPLICATION OF DATABASE Numeric and Textual Database Multimedia Database Geographic Information Systems Data Warehouse and OLAP Real – time and Active Database

ADVANTAGES OF DATABASE Minimal data redundancy Improved data consistency Improved data sharing Enforcement of standards Improved data quality Improved data accessibility Reduced program maintenance

DIS-ADVANTAGES OF DATABASEo Initial installment is high

o Training is required

o Unauthorized access

o Complex recovery

DATABASE SECURITYTypes Of Security:

Legal and ethical issues Policy issues System-related issues The need to identify multiple security levels

TYPES OF SECURITY

Legal and ethical issues:This is regarding the right to access

certain information. Some information may be deemed to be private and cannot be accessed legally by unauthorized persons. Policy issues:

At the governmental, institutional, or corporate level as to what kind of information should not be made publicly available.

Continued…...

System-related issues:Issues such as the system level at which

various security functions should be enforced like hardware level or DBMS level or OS level. The need to identify multiple security levels:

In some organizations there is a need for multiple security levels and to categorize the data and users based on these classifications like top secret, secret, confidential.

SOME IMPORTANT TERMS RELATING TO DBMS:

Data modeling:Data modeling refers to on what type of

data should be stored on the database and how to process the data.

Entities: Entities are the main data objects through which we can collect information. Any occurrence of an entity is called an entity instance.

Continued….

Attributes:Attributes are the behaviors of entities

which provide detailed information about them. Key attribute is used to identify a unique instance of an entity.

Relationships:A relationship represents the association

between one or more entities. Types of relationship are one to-one, many-to-one, one-to-many and many-to-many.

Basic Data Types

CREATE Create command is used to create table in

database.Syntax:CREATE TABLE table name (col1 data type (size),col2….);Eg: CREATE TABLE team (team_id NUMBER(5) PRIMARY KEY,

team_name VARCHAR2(20),owner VARCHAR(20),captain_id NUMBER(10) UNIQUE,coach_id NUMBER(10) UNIQUE,ground_id NUMBER UNIQUE(5));

DESCRIBE

Used to display the structure of the table.

Eg: DESCRIBE teams;

Column Name Constraints Data Type

Team Id Primary key / Unique

Number(5)

Team Name Varchar2(20)

Owner Varchar2(20)

Captain Id Unique Number(10)

Ground Id Unique Number(5)

STRUCTURE - TEAM

INSERT

Used to insert records into a table. Syntax :

INSERT INTO table_name (COL1,COL2,…)

VALUES(VAL1, VAL2…);

E.g.:

INSERT INTO team VALUES(01,’Mumbai Indians’,’Reliance’,101,501,1002);

01 Mumbai Indians Reliance 101 501 1002

TABLE 4 - MUMBAI INDIANS

CONSTRAINTS

Ensures data integrity. Helps to prevent invalid entry into

tables. Enforces rules on the data in a table

whenever a row is inserted, updated or deleted from that table.

Prevent deletion of table if there are dependencies from other table

CONSTRAINT TYPE’S • Not Null Constraint: Specifies that the column cannot

contain a null value• Check constraint: Specifies a condition that must be

true• Unique constraint:• Specifies a column or combination of columns whose

values must be unique for all rows in the table.• Primary Key: Uniquely identifies each row of the table• Foreign Key: Used for referencing data
