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

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

SQL Server features

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

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)

Agenda for Today

Do an installation of SQL Server 2000 on your local machine

Talk about the options for installation

31

Planning for Installation

Planning for Installation– Hardware Requirements – Table 2-1– Memory Requirements – Table 2-2

User Account for SQL Server – local system account (this one has no

network access rights)– domain user account (has network

access rights and is prefered option– Example on Page 41

32

Operating system support

SQL Windows CE edition – Windows CE only

Personal edition – Windows 98, Windows Me, Windows NT 4.0, and Windows 2000

Developer edition – Windows NT 4.0 and Windows 2000

Standard edition – Windows NT 4.0 servers and Windows 2000 servers

Enterprise edition – Windows NT 4.0 servers and Windows 2000 servers

33

Installation decisions Local or remote Installation options Name and company name License agreement CD-Key Component selection Instance name Installation type Services accounts Authentication mode Collation settings Network libraries Licensing mode

34

Ready to Install - CD with book

35

Local or remote - which computer?

36

Installation options - new or upgrade?

37

Name and company

38

Installation definition - types of installation?

39

Default instance or a named instance?

40

Setup types

41

Component selection - select all for our case - Table 2-5

42

Service accounts - local or domain?

43

Authentication - windows or mixed?

44

Collation - storage of data - dic-order-case-insensitive (1252)

45

Net-Libraries - TCP/IP and Name Pipes are default

46

Licensing mode - Per Seat (small) vs. Per Server (big)

47

Named Instances

Multiple instances(copies) on same server

Connect using the syntax:computername\instancename

Used for second and later installations Just review the information in Lesson

4 on Named Instances
