What is SQL Server?

• SQL Server is a Relational Database Management System (RDBMS).

• Microsoft SQL Server is designed to support high-volume transaction processing

as well as data warehousing and decision-support applications.

• SQL Server is part of the core of a family of integrated products that includes

development tools, system management tools, distributed system components,

and open development interfaces.

Types Of Database• Database

– Collection of organized data in a particular order, preferably in rows and columns

• Types of Database

– There are two main types of database; flat-file and relational

• The typical flat-file database is split up using a common delimiter

• The "relation" comes from the fact that the tables can be linked to each other

• There are 5 system databases with Microsoft SQL Server 2012

Data Organization• Logical Structure

– The data in a database is organized into the logical components visible to users.

– Logical components include tables, views, procedures, and users.• Physical Structure

– Data is physically stored on the disk system with in the data files

– Clustered indexed actually forces the physical ordering of the data within the data files

• Meta Data & Catalog

– Metadata describes the database’s structure, components, users, security, and so on.

– Catalog includes system catalog and database catalog.

Metadata Catalogs

• System Tables Store Information (Metadata) About the System and Database

Objects

• Database Catalog Stores Metadata About a Specific Database

• System Catalog Stores Metadata About the Entire System and All Other Databases

• System Stored Procedures

– EXEC sp_help Employees

• System and Metadata Functions

– SELECT USER_NAME(10)

• Information Schema Views

– SELECT * FROM INFORMATION_SCHEMA.TABLES`
