6.What do you understand by report server project?
Report Server Project comprises of RDL file and it need to be deployed on report server to view the report files to application and user. It is a solution where we can design our reports. We can add it by going into BIDS clicking on new item and then selecting reports server project. Once the solution is formed we can start forming reports.

7.Explain report builder?
Report builder is used to create small reports and it is a define interface. We can’t change the report interface in report builder it pre designed. We can just drag columns in the report. It creates reports on database objects available with report model project.
8. In which SQL Server type report builder introduced?
Report builder presented in SQL Server 2005. While creating or arranging report model project on report server we can get error or it might not get formed. For this we need to check whether the service pack 22 is installed or not.
9.How to organise the Report?
Report can be organized in three ways:
1. Using visual studio: In visual studio we can directly deploy the report through solution explorer by providing the report server URL in project properties at Target Server URL. This will organize entire project or single report as per our selection.
2. Using report server: We can directly go to the report server and deploy the report by looking the report from the disk location on server.
3. Creating the utility: SQL server provides the utility which can be used to create a modify utility for our report deployment in bulk.

The major differences between SSRS 2005 and SSRS 2008 are as follows:
SSRS 2005 report server requires IIS, whereas SSRS 2008 comes with a build-in web server and hence does not require IIS.
26.Explain architecture of SSIS?
SSIS architecture involves four key parts:a) Integration Services service:
It monitors running Integration Services packages and accomplishes the storage of packages.
b) Integration Services object model:
It contains managed API for reading Integration Services tools, command-line utilities, and custom applications.
c) Integration Services runtime and run-time executables:
It keeps the layout of packages, runs packages, and provides support for logging, breakpoints, configuration, connections, and transactions.
d) Data flow engine:
It provides the in-memory buffers that move data from source to destination.
27.How we can do Logging in SSIS?
Logging Configuration provides an inbuilt feature which can log the detail of various events like onError, onWarning etc .
28.How we can do Error Handling?
SSIS package contain mainly have two types of errors:
a) Procedure Error: It can be handled in Control flow bythe precedence control and redirecting the execution flow.
b) Data Error: it is handled in DATA FLOW TASK by redirecting the data flow using Error Output of a component.
29.How we can pass property value at Run time?
A property value like connection string for a Connection Manager can be passed to the pkg using package configurations.
30.How can we organize a SSIS Package on production?
A)Through Manifest we can organize it:
1. Create deployment utility by setting its properties as true .
2. It will be formed in the bin folder of the solution once package is build.
3. Copy all the files in the utility and use manifest file to display it on the Prod.
B) Using DtsExec.exe utility.
C)Import Package directly in MSDB from SSMS by logging in Integration Services.
31.Define Execution Tree?
Execution trees demonstrate how package uses buffers and threads. At run time, the data flow engine breaks down Data Flow task operations into execution trees.
32.Differentiate between Unionall and Merge Join?
a) Merge transformation can take only two inputs whereas Union all can take more than two inputs
b) Data has to be sorted before Merge Transformation whereas Union all doesn’t have any boundation like that.
33.How we can restart package from previous failure point? Define Checkpoints and how they are implement in SSIS?
When a package is arranged to use checkpoints, material about package execution is written to a checkpoint file. When the failed package is rerun, the checkpoint file is used to restart the package from the point of failure. If the package runs effectively, the checkpoint file is deleted, and then re-created the next time that the package is run.

Visual Basic .NET Code is used to code embedded fuctions in SSRS.
39.What important terms can be used in the reporting services?
1. Report definition: A report definition contains information about the query and layout for the report.
2. Report snapshot: A report snapshot is actually a report definition that contains a dataset instead of query instructions.
3. Rendered report: A fully processed report that contains both data and layout information, in a format suitable for viewing (such as HTML).
4. Parameterized report: A published report that accepts input values through parameters.
