SQL Server 2005
Overview
Microsoft SQL Server 2005 provides the database developer the opportunity to locate programming code in native formats or create server-driven complex systems. The .NET framework, in combination with the SQL Server 2005, delivers the functionality of the powerful class library in combination with modern programming languages. Common Language Runtime (CLR) is used to code procedures, triggers and functions within the chosen language in the .NET framework. Using object-oriented constructs such as structured exception handling, namespaces, classes and arrays assist the programmer in effectively handling procedural issues when programming with SQL Server 2005.
Training Objective
The SQL Server 2005 is a reliable and productive database management system
that is used in advanced business intelligence systems. The Windows Server
system is cost effective, efficient and secure. The training series intend to
cover Microsoft’s SQL Server 2005 in Express, Workgroup, Standard and Enterprise
editions, including the differences and features of each edition.
Target Audience
Step-by-step installation instructions with screen shots are provided to
assist the beginner, intermediate or advanced level developer and Database
Administrator when setting up the SQL Server 2005.
