This document provides information about SQL Server and database management systems. It defines SQL Server, DBMS, and RDBMS. It lists features of database management including reducing redundancy and avoiding inconsistency, providing security, ensuring data integrity, and atomicity of transactions. It also lists examples of DBMS and RDBMS software and describes features like authentication, authorization, and ACID properties.

3. Sql Server Basics -
• DBMS – Data Base Management
System.
• Data – Collection of Related
Information.
• Database – It is a base or try to store
data.
What is DBMS?
• It is used to store managed
data and to access the data
from database in dbms data
will be stored in the form of
tables.
• Every table will contain 2D
(rows, column).

4. DBMS
SOFTWARE'S
•Fox Pro
•D-Base
•MS - Access
•Oracle
•Sybase
•Ingress
•In form's
•Unify
•DB2
•MySQL
•SQL Server
RDBMS
Software's

5. RDBMS Means dbms concept or Feature with relationship
data model.
Oracle is called platform independent . It will work in
Windows , Unix , Linux , Sunsolaries, etc. It will support
Java & .NET Languages.
Sql Server is called platform dependent. It will works in
Windows OS like Windows xp , Vista , Windows 7 ,
Windows 8, Windows 10, Windows 2008R2 Server ,
Windows2009R2 Server.
Note –
Sql Server Only Support Only .NET Language.

6. DBMS FEATURES
1. Redundancy can be reduced & Inconsistency can be avoided.

In Consistency data
Default Record

7. •Redundancy Means Duplicate data or Data
Replication.
•Inconsistency Means In Correct data or which
data is not meaning full.
•If table contains Redundancy then inconsistent
data may exists in table by using constrains
Redundancy can be reduced & inconsistency
can be avoided.

8. SECURITY
AUTHENTICATION
Authentication means
identification of users.
It will allow the registered (or)
authorized users to work with
db.
It will not allow anonymous
users and unregistered users
to connect to the database
Ex: Username & Password
AUTHORIZATION
Authorization is used to check
whether the users has
permission or right to work
with database & tables

9. DATA INTEGRITY
It is table maintains data integrity then valid or meaningful data can
be stored in tables
Data integrity is maintained by using constraints.

10. ATOMICITY
All the commands in the transaction will be executed as units.
ACID Properties
A Atomicity
C Consistency
I Isolation
D Durability

11. Atomicity is taken from Greek word & called ATOM means (Individual).
In Banking Application, Transaction will be used in Bank Application or ATM
Application
Or Internet Banking or Mobile Application.
If Transaction is completed successfully all the sql commands in transaction
will executed.
If transaction fails not even one command in the transaction will execute.
If transaction is completed successfully all the commands will execute or
none of them are execute.
If one or two commands are executed in the transaction automatically will
cancelled. The execution of the pure sql commands in transaction.
