Topic 1, Trey Research, Scenario

BACKGROUND Company Overview
Trey Research is a nonprofit organization that provides research support to many organizations in the United States.
The company has a single office ,which is located in Chicago.
Planned Changes
The company plans to implement a new SQL Server 2005 failover cluster. This cluster will have one instance for each of three databases that are currently on a mainframe computer. The three databases are named Research., Parts, and Engineering. These
databases will hold mission-critical data. The configuration will use a four-node failover cluster to provide an N+1 configuration. This cluster will named SQLCLUST.
When these databases are moved to SQLCLUST, a new identity column will be added to most tables in all of the databases to create a surrogate primary key. When the databases move to production, the aeed value should be reset for all identity columns.
New Web services-based applications will be designed to access the Parts, Engineering, Customer, and Bids databases. Users will access these applications by using their Windows credentials.
The company plans to reduce database administration cost by consolidating existing SQL Server computers. The company wants to minimize the number of SQL Server computers and SQL Server instances.
The company plans to create a Bid_Archive database. All rows that contain information
on completed bids that do not result in a new extended contract should be moved immediately from the Bids database to Bid_Archive.This information should be available for data retrievasl, but changes should not be made to the Bid_Archive database. EXISTING DATA ENVIRONMENT
Databases
Trey Research currently has eight databases, as shown in the following table.

Data in the Contractor database in read far more frequently than it is modified.
The Bid_Tracking table in the Bids database includes a Completed column that is set to 1
when the bid is no longer active.The table also has a Successful column that is set to 1
when the bid results in a new or extended contract.
Database Servers
The company has three existing SQL Server 2005 computers running with default instances, which contain the databases shown in the following table.

Database Client Computers
Active Directory Infrastructure
The Trey Research network consists of a single Active Directory domain. All users use
Windows user accounts to access SQL Server.
BUSINESS REQUIREMENTS General Requirements
The company will store completed annual performance review forms in the HR database, Each review form will be larger than 9,000 characters. The column that holds the review form should be able to handle multiple languages and alphabets to support expected international growth in the future. The company wants this data to be accessible in a
single column.
The accounting managers must be able to view the current state of the data in the Accounting database at the close of any given day during last seven days. They should be able to undo changes if necessary. Although a single field will not be updated more than once per day, it might be updated on several consecutive days.
Performance
To improve the performance on the Customer database , the company wants to move all

information to a Customer_Archive database that will be available for running long
reports that are currently causing contention problems. Management wants to minimize network traffic between the Customer database and the distribution database. In addition, management wants to use the Customer_Archive database as an added layer of fault tolerance.Although additional servers are available, management prefers to use existing servers.
Availability
The Customer database must not fail when a single hard disk on the server fails. The solution must support hot-swappable drives. Additional hardware is available to support this solution.
Recoverability
The Customer database receives numerous changes daily during the business hours of
09:00 to 17:00. The majority of these changes occur the afternoon hours. Very few changes are made outside of business hours. Business requirements allow for up to one hour of data loss. No more than six backups should be required for any recovery.After performance of different backup scenarios was tested, company policy was revised to state that full database backups should not be performed during business hours nad differential backups should be performed only once during business hours.
TECHNICAL REQUIREMENTS Security
The administrators of the Accounting and HR databases are members of a domain global group named Certkiller A_DBA.
These administrators are responsible for managing all databases and SQL Server configurations on Certkiller A.
Users who are members of the DBAdmins global group are responsible for managing the
SQL Server instances on Certkiller B and Certkiller C
The central IT department manages the physical computers and the Windows operating systems on which the SQL Server computers reside. Members of the DBAdmins group
do not have Windows administrative privileges.
All employee user accounts should be assigned only the minimum permissions that the employees need in order to perform their jobs.
The company’s written security policy states that when users of one database need access
to another database on a separate SQL Server computer or SQL Server inwtance, delegation should be used.
Services should not be installed unless absolutely necessary.
Currently, all employees in the human resources (HR) department need read access to every table in the HR database Hiring managers need to be able to read, add ,delete, and modify data in five tables in the HR database . The company plans to add additional
tables to which only a few HR employees should have read access .In addition ,there will
be future employees who will need read access to only one table.
The company is deploying a new custom application to manage the replication for the
new Customer_Archive database. The company plans to use common language runtime ( CLR) in tegration and CLR stored procedures in the Customer database to provide
limited and controlled access to the shares and files on Certkiller B. All assemblies should be created with dbo as the owner. Maintainability
