You need to improve the performance of the reports
You develop a Microsoft SQL Server 2012 database. You create a view that performs the following tasks:
Joins 8 tables that contain up to 500,000 records each.
Performs aggregations on 5 fields.
The view is frequently used in several reports.
You need to improve the performance of the reports.

Which Transact-SQL statement should you use?
You develop a Microsoft SQL Server 2012 database that has two tables named SavingAccounts and LoanAccounts. Both tables have a column named
AccountNumber of the nvarchar data type.
You use a third table named Transactions that has columns named TransactionId AccountNumber, Amount, and TransactionDate.
You need to ensure that when multiple records are inserted in the Transactions table, only the records that have a valid AccountNumber in the SavingAccounts or
LoanAccounts are inserted.

You develop a Microsoft SQL Server 2012 server database that supports an application.
The application contains a table that has the following definition:
CREATE TABLE Inventory (
ItemID int NOT NULL PRIMARY KEY,
ItemsInStore int NOT NULL,
ItemsInWarehouse int NOT NULL)
You need to create a computed column that returns the sum total of the ItemsInStore and ItemsInWarehouse values for each row.
The new column is expected to be queried heavily, and you need to be able to index the column.

What should you create for each application?
You develop a Microsoft SQL Server 2012 database. The database is used by two web applications that access a table named Products.
You want to create an object that will prevent the applications from accessing the table directly while still providing access to the required data.
You need to ensure that the following requirements are met:
Future modifications to the table definition will not affect the applications’ ability to access data.
The new object can accommodate data retrieval and data modification.
You need to achieve this goal by using the minimum amount of changes to the applications.
