Client-Server Database Management System Version 6.0

Microsoft SQL Server version 6.0 is a scalable, high-performance database management system designed specifically for distributed client-server computing. Its built-in data replication, powerful management tools, and open system architecture provide a superior platform for delivering cost-effective information solutions for organizations of all sizes.

Overview

As businesses continue to streamline processes and decentralize decision making, they depend more on technology to bring users and information together. Increasingly, organizations are turning to distributed computing to move information closer to those who need it for their critical decisions.

Microsoft SQL Server version 6.0 is the first DBMS designed specifically for the new world of distributed client-server computing. It provides -- in one box at one price -- a complete and integrated system of database management software to meet the challenges facing today's businesses.

Powerful, built-in data replication provides a reliable way to disseminate accurate information and improve its availability throughout your enterprise.

A comprehensive distributed management framework lets you centrally manage all the database servers in your organization. With advanced Windows®-based management tools and powerful server-based job scheduling you have visual control over multiple servers and can automate remote operations for "lights out" command of your distributed environment.

Together, these tools help improve business performance and help reduce your operational costs.

The new multithreaded, parallel database design in Microsoft SQL Server delivers scalable high performance on today's cost- effective, standard hardware. It's multiprocessor-ready out of the box so you can take full advantage of the latest high-performance symmetric multiprocessing (SMP) hardware without additional configuration and management complexity.

Microsoft SQL Server also meets the most demanding requirements for reliability, data integrity, and security so you can depend on your distributed systems to safeguard your vital business data from loss or theft.

Through integration with key desktop technologies, SQL Server provides end users with unparalleled data access. And its open architecture -- based on industry standards -- ensures interoperability with the broadest range of applications, development tools, host gateways, and networks.

Many of these performance and reliability gains are achieved through close integration with the Microsoft Windows NTTM Server platform. And as part of the Microsoft BackOffice family, SQL Server works with other BackOffice server applications to offer powerful client-server solutions to help your business perform better.

Highlights

Data replication for reliable distributed systems
The built-in data replication services in Microsoft SQL Server version 6.0 provide reliable, high-performance distribution of data across your enterprise, while preserving transaction integrity and security. Its integrated architecture, aided by an intuitive "publish and subscribe" metaphor and "drag and drop" configuration, makes SQL Server data replication easier to use and more flexible than other replication systems.

The first centralized administration architecture for distributed servers
Microsoft SQL Server incorporates an extensible, object-oriented Distributed Management Framework (SQL-DMF) that addresses the dynamic needs of today's client-server environments with:

Scalable high performance on today's cost-effective hardware
Microsoft SQL Server 6.0 features an enhanced Symmetric Server Architecture, which executes internal database functions in parallel to dramatically increase both performance and scalability on cost-effective multiprocessing hardware.

Parallel data scanning allows SQL Server 6.0 to perform some queries up to 400 percent faster than before. Parallel data loading and indexing also increase performance. And high-speed parallel backup enables very large database (VLDB) support.

Taking full advantage of the native Windows NT threading and scheduling services simplifies the SQL Server architecture, which further improves performance and scalability. Because user tasks are isolated from one another, reliability also increases. And preemptive task scheduling balances the workload automatically across CPUs, providing smoother operations at a lower cost.

Seamless integration with desktop applications
SQL Server is the first DBMS to support key desktop technologies, including OLE, Open Database Connectivity (ODBC), and e-mail.

Because it runs within the Windows computing environment, SQL Server works easily with desktop tools. You can automatically run a query, redirect the results via OLE to the Microsoft Excel charting engine, format the graph and data in a Microsoft Word report, and mail it as an attachment to users. A high-performance native ODBC interface with engine-based cursors provides superior support for today's desktop applications and tools.

Open architecture to protect your computing investments
Microsoft SQL Server has open, published interfaces at both the client and the server to provide unmatched interoperability with hundreds of existing client-server applications and tools. Microsoft Open Data Services is a programmable SQL Server gateway to virtually any external data source. SQL Server works with all popular networks and protocols -- including UNIX® environments -- right out of the box. And you can access host databases -- such as IBM® DB2®, IBM AS/400®, ORACLE®, and SYBASE® -- through gateways developed with ODS or those from third-party vendors.
