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

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

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
