This document provides an overview of Microsoft SQL Server 2005 database editions. It describes the main features and limitations of the Enterprise, Standard, Workgroup, and Express editions. These editions are designed for different organization sizes and needs, with Enterprise having the most advanced features and no limitations, and Express being lightweight with a small database size limit. The document also discusses how SQL Server supports both online transaction processing and online analytical processing workloads through its database engine and Analysis Services.

1. • A database is a software application whose
main purpose is to help people an programs
store, organize and retrieve information
• As more time passed, a database companies
arose
• Oracle, Informix, and Sybase developed a kind
of database known as relational database
• Relational databases are particularly well
designed for storing information in tabular
format

2. • Microsoft also entered the relational database
with the SQL Server database
• Microsoft has created several different
versions of SQL Server 2005 product family
• Known as editions, each of these version
addresses a different class of database
environment
• But all edition are built on the same
underlying technology platform

3. • Here’s a list of all the SQL Server editions:-
Enterprise: Provides a relational database to meet the
exacting needs of the largest enterprises and busiest
online databases. The Enterprise Edition includes
high-end business intelligence support and
clustering.
Standard: Meets the needs of medium-sized
companies or large departments in larger companies.

4. Workgroup: Meets the needs of small- to medium-
sized businesses that don’t require the features of
Standard Edition.
Express: A lightweight edition intended for use by
application, limitation of database size can’t be bigger
than 4GB

10. A Client-Server Database
• SQL Server 2005 is a client-server database.
• SQL Server 2005 database engine is installed on a server machine to which
you connect anything from a few machines to many hundreds or thousands
of client machines.
• A client-server architecture can handle large amounts of data better than a
desktop database such as Microsoft Access.
• The SQL Server instance provides security, availability, and reliability
features that are absent from databases such as Access.
• A client-server architecture also can reduce network traffic.
• SQL Server installation is used for two broad categories of data
processing: Online Transaction Processing (OLTP) and Online Analytical
Processing (OLAP).

11. OLTP
• Online Transaction Processing is the kind of processing that the databases
of Amazon.com or any other large online retailer needs to do.
• A large number of orders come in every minute and the information from
each of those orders needs to be written to the database quickly and
reliably.
• With OLTP, you can group certain actions together.
• For example, the different aspects of a bank transfer between accounts
would be carried out together, if money is moved out of one account, it is
also moved into another account.
• The all or nothing characteristic of a transaction ensures that the data
remains in a consistent state.

12. OLAP
• An Online Analytical Processing database is intended to process large
• amounts of data that doesn’t change often.
• For example, an online retailer might want to store summary data about
sales by month, by region, by product category, and so on.
• In SQL Server 2005, the OLAP functionality is carried out in Analysis
Services. In Analysis Services, you create cubes that allow you to examine
dimensions of a cube.
• OLAP often takes place in a data warehouse.

13. Programmable database
• SQL Server 2005 is a great environment for programmers.
• SQL Server 2005 supports the Structured Query Language (SQL).
• SQL Server satisfies some standard SQL syntax and adds its own
extensions to SQL, allowing you to easily write code.
• Microsoft flavor of SQL is called Transact-SQL (T-SQL) which allows you
to add, modify, or query relational in SQL Server 2005.
• Transact-SQL programming is commonly done in the query pane of SQL
Server Management Studio.

14. A Scalable Database
• A database management system, such as SQL Server 2005,
must grow as your business grows.
• Table 1-2 summarizes some key features of the various
editions of SQL Server 2005 and lists the limitations of each

The following table lists the minimum hardware and software
requirements for running Microsoft SQL
Server 2005 Express Edition on a 32-bit machine.

Windows (WOW) 32-bit subsystem on 64-bit operating
systems.
