Scenario: Database2 will contain a table named Inventory. Inventory will contain over 100 GB of data. The Inventory table will have two indexes: a clustered index on the primary key and a nonclustered index. The column that is used as the primary key will use the identity property.

* c Clause (Transact-SQL) In SQL Server you can define the execution context of the following user-defined modules: functions (except inline table-valued functions), procedures, queues, and triggers.Reference: Using EXECUTE AS in Modules

* Scenario: You must encrypt the backup files to meet regulatory compliance requirements. The encryption strategy must minimize changes to the databases and to the applications.* Transparent data encryption (TDE) performs real-time I/O encryption and decryption of the data and log files. The encryption uses a database encryption key (DEK), which is stored in the database boot record for availability during recovery. Reference: Transparent Data Encryption (TDE)

* Scenario: / Data from Database2 will be accessed periodically by an external application named Application1 / Application developers must be denied direct access to the database tables. Applications must be denied direct access to the tables. Reference:Tutorial: Signing Stored Procedures with a Certificate

Reference:Dynamic Management Views and Functions (Transact-SQL)

*Scenario: Database2 will contain a stored procedure named usp_UpdateInventory. Usp_UpdateInventory will manipulate a table that contains a self-join that has an unlimited number of hierarchies.* A table variable can be very useful to store temporary data and return the data in the table format. table * Example: The following example uses a self-join to find the products that are supplied by more than one vendor.Because this query involves a join of the ProductVendor table with itself, the ProductVendor table appears in two roles. To distinguish these roles, you must give the ProductVendor table two different aliases (pv1 and pv2) in the FROM clause. These aliases are used to qualify the column names in the rest of the query. This is an example of the self-join Transact-SQL statement:USE AdventureWorks2008R2; GO SELECT DISTINCT pv1.ProductID, pv1.VendorID FROM Purchasing.ProductVendor pv1     INNER JOIN Purchasing.ProductVendor pv2     ON pv1.ProductID = pv2.ProductID         AND pv1.VendorID <> pv2.VendorID ORDER BY pv1.ProductID Incorrect:Not B: Using a CTE offers the advantages of improved readability and ease in maintenance of complex queries. The query can be divided into separate, simple, logical building blocks. These simple blocks can then be used to build more complex, interim CTEs until the final result set is generated.

Scenario: The databases must be available if the SQL Server service fails.Reference:Failover Clustering Overview Windows Server Failover Clustering (WSFC) with SQL Server

Scenario: * Data from Database2 will be accessed periodically by an external application named Application1. The data from Database2 will be sent to a database named App1_Db1 as soon as changes occur to the data in Database2. * All data in Database2 is recreated each day and does not change until the next data creation process. Reference:Transactional Replication

* Scenario: System administrators must be able to run real-time reports on disk usage.* The data collector provides an historical report for each of the System Data collection sets. Each of the following reports use data that is stored in the management data warehouse:Disk Usage Summary Query Statistics History Server Activity History You can use these reports to obtain information for monitoring system capacity and troubleshooting system performance. Reference:System Data Collection Set Reports

* Scenario: Databasel will also contain a stored procedure named usp_UpdateOrderDetails. The stored procedure is used to update order information. The stored procedure queries the Orders table twice each time the procedure executes. The rows returned from the first query must be returned on the second query unchanged along with any rows added to the table between the two read operations.* REPEATABLE READ Specifies that statements cannot read data that has been modified but not yet committed by other transactions and that no other transactions can modify data that has been read by the current transaction until the current transaction completes. Reference: Transaction Isolation Levels
