Microsoft SQL Server 2000 (Single Marks questions of Msc(IT)-1)

[1]. What is SQL Server 2000?

SQL Server 2000 is an RDBMS that uses Transact-SQL to send requests between a client computer and a SQL Server 2000 computer. An RDBMS includes databases, the database engine, and the applications necessary to manage the data and the components of the RDBMS. The RDBMS organizes data into related rows and columns within the database.

[2]. What language is commonly used to work with data in a database?


[3]. What is XML?

XML is a standard format for data on the Internet. XML consists of tags within a text document that define the structure of the document. XML documents can be easily processed through HTML. Although most SQL statements return their results in a relational (tabular) result set, the SQL Server 2000 database component supports a FOR XML clause that causes the results to be returned as an XML document. SQL Server 2000 also supports XPath queries from Internet and intranet applications.

[4]. Which edition of SQL Server 2000 includes the complete SQL Server offering?

SQL Server 2000 Enterprise Edition

[5]. What is the purpose of the SQL Server 2000 relational database engine?

The SQL Server 2000 relational database engine is a modern, highly scalable engine for storing data. The database engine stores data in tables. Applications submit SQL statements to the database engine, which returns the results to the application in the form of a tabular result set. Internet applications submit either SQL statements or XPath queries to the database engine, which returns the results in the form of an XML document. The relational database engine provides support for common Microsoft data access interfaces, such as ADOs, OLE DB, and ODBC.

[6]. What SQL Server 2000 technology helps you build data warehouses and data marts in SQL Server by importing and transferring data from multiple heterogeneous sources?


[7]. What are at least four administrative tasks that you can use the Enterprise Manager to perform?

Any four of the following tasks:

Defining groups of servers running SQL Server

Registering individual servers in a group

Configuring all SQL Server options for each registered server

Creating and administering all SQL Server databases, objects, logins, users, and permissions in each registered server

Defining and executing all SQL Server administrative tasks on each registered server

Designing and testing SQL statements, batches, and scripts interactively by invoking Query Analyzer

Invoking the various wizards defined for SQL Server

[8]. Which tool is commonly used to create queries and execute them against SQL Server databases?

Query Analyzer

[9]. What are at least five objects that can be included in a logical database?

Table,Data type,View,Stored procedure,Function,Index,Constraint,Rule,Default,Trigger

[10]. What are the major components involved in processing a SQL statement received from a SQL Server client?
