Best Practices

When you write stored procedures, triggers, and
user-defined functions, first decide whether to use traditional
Transact-SQL or a programming language that is
compatible with the .NET Framework, such as Visual Basic
.NET or C#.
Use Transact-SQL where the code primarily performs data
access with little or no procedural logic
Use programming languages when you have
computationally-intensive functions and procedures that
feature complex logic or for situations where you want to take
advantage of the .NET Framework class library.
To rotate the data of a table use the PIVOT and UNPIVOT
operators, instead of using complex JOIN statements.

Best Practices (Contd.)
Use the new data types VARCHAR(MAX),
NVARCHAR(MAX), and VARBINARY(MAX) for storing long
columns.
In the Query Editor Results window, use the Options tab in
Management Studio to set the maximum column size under
the Results section.
Keep the result sets that you return from your database
small to improve performance.

Tips and Tricks
Coll aborate Session 1
When writing calculation expressions such as “expr1 *
expr2”, ensure that the expression sweeping the largest
area/volume is on the left side.
Consider replacing simple “Measure1 + Measure2”
calculations with computed columns in the SQL data source.
Avoid using Select * in your query design. Instead,
ensure that you use the proper column names in the query.

Can we use the PIVOT and UNPIVOT operators in SQL
Server 2000?
No, SQL Server 2000 does not support the PIVOT and
UNPIVOT operators. To achieve the same functionality as that
of the PIVOT and UNPIVOT operators, you can use JOINS in

SQL Server 2000.

1.14 Instructor Inputs ¤NIIT
SQL Server 2005 provides a data management solution for the organization. It allows
secure and efficient storage and management of data. In addition, SQL Server 2005
provides other components and services that support the business intelligence platform to
generate reports and facilitate data analysis.

Discuss the role of each core component of SQL Server 2005 in an enterprise
environment.
Instructor Inputs
You can conduct the discussion as follows:
 Begin the discussion by listing the different core components of SQL Server 2005.
 Encourage the students to discuss about the data management support of database
engine.
 Continue the discussion by mentioning about the data integration requirement of the
enterprises and role of Integration services in this context.
 Move the discussion to the need of analysis services and reporting services.
Solution
The different core components of SQL Server 2005 are as follows:
 Database Engine
 Integration Services
 Analysis Services
 Reporting Services
Database Engine
The database engine provides support to store, query, process, and secure data on the
database server. The database engine contains databases and database objects, such as
tables and procedures. This database engine allows you to create and manage database
objects. Apart from providing support for data management, the database engine also
provides the following background services:
 Service Broker: Provides support for asynchronous communication between clients
and the database server, enabling reliable query processing.
 Replication: Allows you to copy and distribute data and database objects from one
database server to another.

¤NIIT Instructor Inputs 1.15

Full-text search: Allows you to implement fast and intelligent search in large

databases by allowing you to search records containing certain words and phrases.
 Notification services: Allows you to generate and send notification messages to the
users or administrators about any event.
Integration Services
Organizations have their old data in the legacy data storage systems. This data they may
require in future for some analysis purposes. Integration services allow you to gather and
integrate data from various disparate data sources available in an organization.
Organizations can also have different branches and these branches of the organization
may use different data storage technologies to store the operational data. You can store
the data in a consistent format in a common database called the data warehouse using the
Integration services
Data is contributed from multiple branches of an organization, each using different
conventions and standards. Before the data can be used, it may need to be formatted
differently. For example, you may need to combine the first name and the last name into
one column. This standardization of the data can be done using Integration services.
Analysis Services
Analysis services help in data analysis in a BI application. These applications are built on
a data warehouse that contains data consolidated from various data sources. These
services provide data mining solutions that are built on data integrated in the data
warehouse.
Reporting Services
Reporting services provide support to generate comprehensive reports on data in the
database engine or in the data warehouse. These services provide a set of tools that help in
creating and managing different types of reports in different formats.
