What is an RDBMS ?

An RDBMS is a Relational Database Management System. An RDBMS is a collection of software that stores, modifies and retrieves data and accesses it through relationships between sets of data.

There are many RDBMS’s available such as Oracle Corporation’s Oracle, IBM’s DB2, and Micorsoft’s SQL Server 2000.

What is an RDBMS (ctd)?

• Maintains relationships among data in database

• Ensures that data is stored correctly and that rules defining the relationship among data are not violated

• Recovers all data to a point of known consistency in the event of system failure

• Provides ways to easily retrieve and manage data

What is SQL 2000 Server?

SQL Server is an RDBMS that can be used to perform

• Transaction Processing (i.e. OnLine Transaction Processing); for example to process a customer’s purchase at a store

• Transaction Analysis (i.e. OnLine Analytical Processing); for example to produce a sales summary

CLIENT SERVER ARCHITECTURE

What is a SERVER ?

A server manages data and allocates server resources such as memory and network bandwidth.

WHAT IS A CLIENT?

• A client is the software allowing connection to the server

• Client is responsible for processing business logic (eg does this customer have good credit) and presenting data to the user.

• Client could be either on the same computer as the server or on a different computer

• There are two ways to connect client programs to a server: ODBC and OLE-DB

Connectivity - ODBC

ODBC (Open DataBase Connectivity)

• An older technology

• Needs an ODBC driver from control panel

• The client’s machine has to be Windows O/S

• Programs and Web pages can use this setting

Connectivity – OLE-DB

OLE-DB

• Newer technology

• The process involves connecting to the server through program strings

• Normally used in Visual Basic or ASP in Internet Servers

• A client side setting is required that is defined by vendors

• Could be upgraded to full version of SQL2000 Server with bundle software.

• Not limited to number of concurrent users but still more than five connection should not be established

• Uses “Write ahead” log

SQL 2000 VERSION: Personal

• Intended for single use application and development

• Same features with standard edition but with limited depth

• No clustering, Network Libraries, Full text indexing and encryption.

• Can be installed on several O/S: Windows 98 and up, Windows NT Workstation, Windows 2000 Professional

• Doesn’t support more than two processors

• When installed on 9X and ME it doesn’t support OLAP.

• Suitable for developer to test application

SQL 2000 VERSION: Standard

• Can handle small to mid range server

• Has all features for SQL Server 2000 –Database Engine, Management tools, Web Wizards and Interfaces, XML Support, Replication, Import and Export, OLAP

• Does not have index view (Materialized view) and Web enabled analysis

• O/S has to be Windows NT 4 or Windows 2000 Server family.

SQL 2000 VERSION: Enterprise

• The “Big Workhorse” of the bunch

• Needs more hardware but provides faster response

• Operating system has to be NT 4 Server Enterprise (SP 5+), W2K Advanced Server or Data Center

• Can scale up to 64 GB RAM and 32 Processors

• Allows four-node fail over cluster

• Provides better analysis services

• Supports Index views

• Supports distributed partition view

SQL 2000 LICENSING

• Licensing is an agreement with the software vendor to access the software

• Check with Microsoft for recent updates on Licensing

• There are two types of licensing SQL Server supports

• Per processor

• Server/ per seat (CAL)

LICENSING: Per Processor

• Pay for a processor license for each processor on the server running the SQL Server software.

• A per processor license allows an unlimited number of users to connect from either inside or outside corporate network

LICENSING: Per Seat (CAL)

• Requires a separate Server License for each server on which the software is installed and a CAL for each client device

• This option is good for SQL 2000 Standard or Enterprise version
