Oracle, SQL Server, Microsoft Access, MySQL, DB2, Paradox. There are quite a variety of database products on the market today, making the
selection of a platform for your organization's infrastructure a daunting project.
Define Your Requirements
Database management systems (or DBMSs) can be divided into two categories -- desktop databases and server databases. Generally speaking,
desktop databases are oriented tow ard single-user applications and reside on standard personal computers (hence the term desktop).
Server databases contain mechanisms to ensure the reliability and consistency of data and are geared tow ard multi-user applications. These
databases are designed to run on high-performance servers and carry a correspondingly higher price tag.
It's important to do a careful needs analysis before you dive in and commit to a database solution. You'll often find that a desktop database is
suitable for your business requirements w hen you originally planned to purchase an expensive server-based solution. You may also uncover
hidden requiremests that necessitate the deployment of a scalable server-based database.
The needs analysis process w ill be specific to your organization but, at a minimum, should answ er the following questions:
Who w ill be using the database and what tasks will they perform?
How often w ill the data be modified? W ho will make these modifications?
Who w ill be providing IT support for the database?
What hardw are is available? Is there a budget for purchasing additional hardware?
Who w ill be responsible for maintaining the data?
Will data access be offered over the Internet? If so, w hat level of access should be supported?
Once you've gathered the answers to these questions, you'll be prepared to begin the process of evaluating specific database management
systems. You may discover that a sophisticated multi-user server platform (like SQL Server or Oracle) is necessary to support your complex
requirements. On the other hand, a desktop database like Microsoft Access might be just as capable of meeting your needs (and much gentler on
your pocketbook!)
Desktop Databases
Desktop databases offer an inexpensive, simple solution to many less complex data storage and manipulation requirements. They earn their name
by virtue of the fact that they are designed to run on “desktop” (or personal) computers. You’re probably familiar with a few of these products
already – Microsoft Access, FoxPro, FileMaker Pro, Paradox and Lotus Approach are the major players.
Let’s examine a few of the benefits gained by utilizing a desktop database:
Desktop databases are inexpensive. You’ll find that most desktop solutions are available for around $100 (compared to thousands of dollars
for their sever-based cousins). In fact, if you ow n a copy of Microsoft Office Professional, you’re already a licensed owner of Microsoft Access.
Desktop databases are user-friendly. A thorough understanding of SQL is not required when using these systems (although many do support
SQL for die-hards out there). Desktop DBMSs usually offer an easy-to-navigate graphical user interface.
Desktop databases offer web solutions. Many modern desktop databases provide web functionality enabling you to publish your data on the
w eb in a static or dynamic fashion.
Server Databases
Server databases, such as Microsoft SQL Server, Oracle and IBM DB2, offer organizations the ability to manage large amounts of data efficiently
and in a manner that enables many users to access and update the data simultaneously. If you’re able to carry the hefty pricetag, a server-based
database can provide you with a comprehensive data management solution.
The benefits achieved through the use of a server-based system are diverse. Let’s take a look at a few of the more prominent gains achieved:
Flexibility. Server-based databases can handle just about any data management problem you can throw at them. Developers love these
systems because they have programmer-friendly application programmer interfaces (or APIs) that provide for the rapid development of
database oriented custom applications. The Oracle platform is even available for multiple operating systems, providing Linux junkies w ith a level
playing field when paired off against the Microsoft folks.

Choosing a Database
Powerful performance. Server-based databases are as powerful as you want them to be. The major players are able to efficiently utilize just
about any reasonable hardware platform that you’re able to construct for them. Modern databases can manage multiple high-speed processors,
clustered servers, high bandw idth connectivity and fault tolerant storage technology.
Scalability. This attribute goes hand-in-hand with the previous one. If you’re willing to provide the necessary hardw are resources, server
databases are able to gracefully handle a rapidly expanding amount of users and/or data.
