1 SQL Server 2000 Administration Kashef Mughal MSB

2 SQL Server 2000 Administration Introductions – Name, experience with databases or SQL Server, objectives for this class, any hobbies Contact information Breaks, dinner etc. Syllabus and Addendum Grading Scale Attendance Concerns Any questions?

3 Database Basics What is a database? A database is a collection of related information What are the building blocks of a db? Tables, fields and records What are popular kinds of databases? Access, Sybase, SQL Server, Oracle etc.

4 Database objects - Table 1-7 Table (most important object) Data type Default View Stored procedure User-defined function Trigger Constraint Index

5 Tables A table contains data on a specific item like customers, orders etc. Tables are collections of rows and columns like a spread sheet A column a.k.a. field defines a unique entity like SSN, Customer Name etc A rows a.k.a record is a group of related data items (fields) treated as one unit of information Discuss Customer table in Northwind

6 Background of SQL Server Collaboration with Sybase for OS/2 Decided to abandon OS/2 for Win NT SQL Server 4 for Windows NT SQL Server 6 and then SQL Server 6.5 SQL Server 7 (November of 1998) SQL Server 2000 (August 2000) SQL Server YUKON?

7 Administrator vs. Developer Administrator has the following tasks: Backup and restore the database, manage the users and security, setup tasks, alerts and operators, optimize the database Developer has the following tasks: Business analysis, design the database objects, writing Transact SQL, design the GUI Reality is that you need to know both

8 Client/server computing Client/server applications – application is divided into functional components, client (end user) and server The advantage is that you can dedicate the resources on the Server side and also minimize administration For example SQL Server is a Server Application, and Visual Basic could be a Client Application

9 Client access to SQL Server Many options for the client to access data Transact-SQL English Query OLE DB/ODBC-OLE DB ActiveX Data Objects (ADO)

10 Transact-SQL (T-SQL) SQL (pronounced sequel or SQL) is the universal language for database. For SQL Server the dialect is T-SQL TSQL has two types –Data Definition Language (DDL) – used to create and modify databases e.g. CREATE DATABASE –Data Manipulation Language (DML) – used to enter, modify, and extract data e.g. SELECT * FROM CUSTOMERS

11 SQL Server editions Personal edition Standard edition Enterprise edition Enterprise Evaluation edition (we are using this one) Developer edition Windows CE edition Desktop edition Table 1-1

12 SQL Server features Centralized management Data replication Distributed transactions Distributed data Data Transformation Services (DTS) Named instances Operating system integration

13 SQL Server services MSSQLServer SQL Server Agent MS DTC Microsoft Search MSSQLServerOLAPService Table 1-2

14 Communication components Client Server

15 Network libraries Named Pipes (default) Multiprotocol TCP/IP Sockets (default) NWLink IPX/SPX AppleTalk Banyan VINES Shared Memory VIA Giganet Table 1-5

16 Default Net-Libraries Server not supported TCP/IP SocketsWindows 95 TCP/IP Sockets and Shared Memory TCP/IP SocketsWindows 98/ Windows Me TCP/IP Sockets, Named Pipes, and Shared Memory TCP/IP Sockets and Named Pipes Windows NT 4.0 TCP/IP Sockets, Named Pipes, and Shared Memory TCP/IP Sockets and Named Pipes Windows 2000 ServerClientOperating system

17 Client tools installation

18 Default components

19 Client configuration General tab

20 Client configuration Alias tab

21 Server configuration

22 Network communications If none of the client systems can connect with the server, the problem is likely with the server. If none of the clients can connect with the server or any other system on the network, the problem is probably a general network failure. If other clients can connect to the server, the problem is likely with the one client.

23 System databases master – controls all user databases and SQL Server operations model – copy source for creating user databases tempdb – temporary storage pubs – sample database Northwind – sample database msdb – SQL Server Agent support Table 1-6

24 Security in SQL Server Two Levels –Authentication determines if the user can connect to SQL Server –Authorization determines what activities the user can perform once they pass the first level

25 Authentication modes Authentication is at the Server level Defined by the login ID Two types: –Windows Authentication mode Windows authentication only Uses Windows users and groups –Mixed mode Windows or SQL Server authentication Windows users and groups SQL Server login accounts Windows Authentication is preferred

26 Authorization Authorization is at the database level Defined by the the user accounts DBA associates a login ID with a user account e.g. SA login ID is associated with dbo user account Guest User Account – new login is associated with this account Roles – similar to Groups Every user in a database belongs to the Public role (similar to Everyone)
