Database Concepts

Compare and contrast Microsoft Access, Microsoft SQL Server, DB2, and Oracle database programs

Providers: Microsoft Corporation provides Microsoft Access and SQL Server, Oracle by Oracle Corporation and DB2 is a product of IBM.

Brief about each:

MS Access: Microsoft Access is a database, which comes bundled in Microsoft Office Products. Access is fully compatible with Active Server Pages (ASP) scripting. Database programs such as Access (sometimes called Relational Database Management systems or RDBMS) are used to store information, often large amounts of information. It can be used as a flat-file database (using a single table) or a relational database (using more than one table linked together). Access database applications can be produced for a large number of database situations including financial and scientific data - with excellent results. Access comes equipped with Wizards, which help the novice to create tables, forms, queries and reports. A complicated relational database design and implementation may need the advice and help of a technical consultant. Access has a Query Wizard to help you create the following types of query: Crosstab, Duplicate, Find Unmatched and Simple

Oracle: Oracle Corporation is the largest software company whose primary business is database products. Historically, Oracle has targeted high-end workstations and minicomputers as the server platforms to run its database systems. Its relational database was the first to support the SQL language, which has since become the industry standard. The standard query language SQL is used to interact with the database. Oracle is not recommended for small databases or for users without relational database experience.

DB2: Abbreviated name for IBM DB2 Universal Database developed as a relational database by IBM. It runs on non-IBM machines as well as IBM hardware and full-featured, robust, scalable and easy to use database.

SQL Server: It is a Relational Data Base Management System (RDBMS) from Sybase Corporation. SQL Server was designed for client/server use and is accessed by applications using SQL. It runs on OS/2, Windows NT, NetWare servers, VAXen, and UNIX workstations. When capitalized, the term generally refers to either of two database management products from Sybase and Microsoft.

Comparative Study of Microsoft Access, Microsoft SQL Server, DB2, and Oracle database programs on following parameters:

A. Hardware requirements

Processor: Pentium 166 MHz or higher for SQL Server

Pentium 75 MHz or higher for Microsoft Access 2000

Pentium 166 MHz or higher for Oracle

Pentium or Pentium compatible CPU for DB2

B. Memory requirement:

Beside minimum 256 MB RAM, additional memory may be required for DB2 in a window-based platform.

SQL Server 2000, it varies from 32 MB to 128MB or more depending o whether it is on Desktop or some other editions.

Oracle requires minimum of 128 MB RAM (though 256 MB recommended) and it also require a virtual memory of 200MB in an Intel or compatible platforms.

For Microsoft Access it depends on the window version (Ex. 32MB RAM for Window NT)

C. Software requirements:

MS Access and SQL Server 2000 can work on any of the Window editions.

Oracle can run on SQL as well as Sun Solaris platform.

DB2 run on mainframe. It also support Java and XML

D. TPC tests:

The Transaction Processing Performance Council (TPC.Org) is an independent organization that specifies the typical transactions and measures the performance and price/performance of transaction processing systems. As an OLTP system benchmark, TPC-C simulates a complete environment where a population of terminal operators executes transactions against a database. The benchmark is centered on the principal activities (transactions) of an order-entry environment.

Oracle gives TPC-C Benchmark Result. DB2 gives TPC-C Benchmark Result. In fact IBM's DB2 has topped TPC Benchmark List. Server 2000 ranks number one on Windows in both TPC-C clustered and non-clustered benchmarks.

E. Platform comparison:

Both Oracle 9i Database and DB2 Universal Database version 8.1 support all known platforms, including Windows-based platforms, AIX-Based Systems, HP-UX systems, Linux Intel, Sun Solaris and so on.

SQL Server 2000 only works on Windows-based platforms, including Windows 9x, Windows NT, Windows 2000 and Windows CE.

Microsoft Access 2000 can….....
