3. Client/Server Architecture
Server provides services for the Clients which are responsible for interacting with the users (Input/Output)
Server is responsible for performing a service (e.g. transaction) and guaranteeing the integrity of the data
Well suited for distributed systems handling large amounts of data

5. What is SQL? Structured Query Language
It is the standard language for managing a database
Creating,
Accessing
Searching
Modifying
Many different Systems depending on maker of software:
Oracle
Microsoft SQL Server
MS Access
Sybase etc.
Initially we will examine SQL under MS Access
non-standard SQL
In the main we use MS SQL Server 2000
standard SQL
Some Variations in symbols
ACCESS SQL

6. MS SQL Server V MS Access
MS SQL Server is a server based database.
Multi User – Multi Platform Systems
Large, high volume traffic database systems
Server holds database. Workstation provides access.
For web or database systems if the access traffic is likely to generate more than 20 concurrent database hits at a time, it's time to move to a database server
Generally, database servers like MS SQL Server are the way to go for database or web/database systems
Many and wide ranging user base for system
Additional Security and Login features
MySQL (free sql database used for connectivity to Websites via PHP).
MS Access is Desktop based
Small, low-traffic database systems
Small, low-traffic web sites requiring database connectivity.
Cannot handle heavy traffic from multiple users.

9. Management Studio Express (MSE)
MS SQL Server 2005
Management Studio Express (MSE)
MSE is the development environments for server based databases. Traditionally installed on servers only.
Administrators and Developers access via MS SQL client tools installed on workstation.
Users access via workstation either by MS SQL client tools or other software packages such as MS Access, MS VBasic, Macromedia Dreamweaver, etc
Develop DB via Graphical UI
Draw ER model in design view
Create tables in design view
Drag and drop relationships links
Automatically creates tables from ER Model
Easy to navigate existing DBs
Develop DB via Scripting UI
Write SQL code to reflect ER model
SQL code held in a Script File
Script Files of SQL code in notepad or word
Use SQL code to create tables & relationships
More powerful, less intuitive

13. Management Studio Scripting User Interface SUI - develop and write SQL Code to implement database
The most popular, and now standard, language for manipulating tables in a relational database is SQL.
SQL, often known as a query language, is a combined DDL, DML and DCL used with relational databases.
Data Definition Language (DDL)
is used to specify the data in a database.
The DDL statements define database objects, eg databases, tables, views, indexes, users, constraints, user-defined data types: CREATE, DROP, ALTER
Data Manipulation Language (DML)
is used to access the data in a database.
The DML statements manipulate data: SELECT, INSERT, DELETE, UPDATE
Data Control Language (DCL)
is used to control access to the data in a database.
The DCL statements control access to data: GRANT, DENY, REVOKE

14. SQL Query Code Example USE MASTER GO
-- If the database already exists, drop it
IF EXISTS(SELECT * FROM sysdatabases WHERE name='Restaurants')
DROP DATABASE Restaurants
-- Create the Restaurants database
CREATE DATABASE Restaurants
USE Restaurants GO
-- Create the Widgets table in Restaurants
CREATE TABLE RestaurantTable (
RestaurantId INT NOT NULL PRIMARY KEY IDENTITY(1,1),
RestaurantName VARCHAR(50) NOT NULL,
Rating SMALLINT DEFAULT 3,
AvgMealPrice MONEY NOT NULL,
ReservationReqd BIT NOT NULL DEFAULT 0 )

15. SQL Server Object Names
Standard Identifiers
Can contain from one to 128 characters, including letters, symbols or #) and numbers.
No embedded spaces are allowed.
The first character must be alphabetic.
A name beginning denotes a local variable or parameter.
A name beginning with # denotes a temporary table or procedure.
A name beginning with ## denotes a global temporary object.
NB: Names for temporary objects shouldn’t exceed 116 characters including # or ## as SQL Server gives them an internal numeric suffix.
Delimited Identifiers
Do not comply with the rules for standard identifiers and must, therefore, always be delimited.
You can use delimited identifiers when:
Names contain embedded spaces.
Reserved words are used for object names or portions of object names.
You must enclose delimited identifiers in square brackets or quotation marks when you use them in Transact-SQL statements, eg:
SELECT * FROM [Blanks In Table Name]
SELECT * FROM “Blanks In Table Name”
NB:You can always use bracketed delimiters but can only use quotation marks if the SET QUOTED_IDENTIFIER option is on.

Review the attached set of SQL notes over the next four weeks to reinforce your SQL skills.
Data Models are converted to schemas which are readable by the database management system.
Notation standardised through SQL and XML
Schemas describe data.
Described as tables (relations) for relational databases.
