You have a legacy application. You do not have access to the application source code. The application has a large denormalized table that contains 100 columns. The application uses stored procedures and views to perform all data manipulation language (DML) activities on the table. You need to optimize the performance of the application to meet the following requirement:
* Reduce I/O
* Minimize the storage requirements
* Optimize insert, update, and delete operations
What should you do?

You are designing a database for a reporting solution that is based on data from an Online Transaction Processing (OLTP) database. The reports will contain aggregated data. You need to ensure that the reports will not affect query performance on the OLTP database. The solution must minimize the use of joins when performing the aggregate calculations. What should you do?

You need to provide a developer the ability to create and modify database diagrams from an existing database by using SQL Server Management Studio. The solution must minimize the amount of permissions assigned to the developer. What should you do?

You have a database that contains two tables named Table1 and Table1_Details. Table1_Details contains details about items in Table1. You need to ensure that when an item is removed from Table1, all related items are removed from Table1_Details. You must achieve this goal by using the minimum amount of Transact-SQL code. What should you do?

You have a table in a database that contains 30 million rows. You need to ensure that the table meets the following requirements:
* Enables queries on all string values within the table
* Enables queries to be returned by order of proximity
* Minimizes the amount of time required to execute queries
What should you do?

You need to design a database solution that meets the following capabilities:
* Executes SQL Server Integration Services (SSIS) packages
* Executes Transact-SQL Schedules tasks
* Sends alerts
Which SQL Server component should you use?

You are a database solutions architect. Your company plans to develop a solution by using a SQL Server 2008 instance. The solution has the following business requirements: + Import data from various data sources such as Microsoft Office Excel, Microsoft SQL Server 2000, Microsoft SQL Server 2005, and CSV files.
+ Profile the source data before it is imported.
+ Provide collaboration and offline capabilities to mobile users.
+ Allow mobile users to use heterogeneous data stores.
You need to configure the appropriate SQL Server components to accomplish the business requirements. You want to achieve this goal by using the minimum amount of administrative effort. Which two SQL Server components should you use? (Each correct answer presents part of the solution. Choose two.)

There is a query that uses SUM, AVG and MAX. To improve performance:

Your company requires a standard code snippet to be inserted at the beginning of all stored procedures meeting the following requirements:
+ Stored procedures should be able to call other stored procedures
+ All stored procedures must incorporate transactions
Here is the core part of the snippet

char(36) @TransName = newID()
If <insert answer here>
Save Transaction @TranName
Begin Transaction

Database used in three different timezones. What to do so that value can be read everywhere?
