Explain what data regions are and what are the different data regions?
Data regions are report items that show repeated rows of summarized information from datasets.
Different data regions include
Chart
Gauge
List
Matrix
Table
Explain what are the different stages of Report Processing?
Different stages of Report Processing includes
Compile: It analyze expressions in the report definitions and save the compiled intermediate format internally on the server
Process: It run dataset queries and combine intermediate format with data and layout
Render: It sends processed report to a rendering extension to tell how much information fits on each page and create the page report
Export: It exports the reports to a different file format
What is Tabular Report in SSRS?
Tabular report is the simplest of the SSRS Report. It lets you just simply display the data using table.
How does the report manager work in SSRS?
Report manager is a web application. In SSRS it is accessed by a URL. The interface of this Report manager depends on the permissions of the user. This means to access any functionality or perform any task, the user must be assigned a role. A user with a role of full permissions can entire all the features and menus of the report. To configure the report manager, a URL needs to be defined.
Mention what are the new features in SSRS?
New features in SSRS includes
Excel File Export: The files can be exported into Excel file formats, earlier only XLS files were only exported
Data Alerts: The new data alerts allow to create alert threshold which are evaluated on a user defined schedule, also there is data alert manager for alerting administrators
Power View: With the new RDLX file format, power view is a new interactive Business Intelligence feature
These are the new features included, apart from these, if you are using SSR on SharePoint it gives additional benefits like drag and drop ad hoc reporting and sending e-mails when data changes.
What are the Reporting Services components?
Reporting services components assist in development. These processing components include some tools that are used to create, manage and view reports. A report designer is used to create the reports. a report sever is used to execute and distribute reports. a report manager is used to manage the report server.
SQL Server Reporting Services vs Crystal Reports.
Crystal reports are processed by IIS while SSSR have a report server. Caching in Crystal reports is available through cache server. On the other hand, caching in SSSR is available for Report history snapshots. Crystal reports have standards and user defined field labels. SSSR allows only user defined field labels.
How do you configure a running aggregate in SSRS?
You can use the RunningValue function to configure a running aggregate.
What is the main purpose of a report parameter?
The main purpose of a report parameter is to add interactivity to your reports, letting users change the report behavior based on options they select.
What is the main purpose of a query parameter?
The main purpose of a query parameter is to filter data in the data source.
You want your users to select a parameter from a list of values in a list box. How should you configure the parameter?
You should create a data source that contains the possible values and then bind the data source to the parameter.
What is the main benefit of using embedded code in a report?
The main benefit of using embedded code in a report is that the code you write at the report level can be reused in any expression in the report.
Explain how you can deploy an SSRS report?
SSRS report can be deployed in three ways
By Visual Studio: You can directly deploy the report in Visual Studios through solution explorer, by declaring the report server URL in project properties at Target Server URL.
By Report Server: By browsing the report from the disk location of the server you can deploy the report to report server
By creating the Utility: Another option is to create customized utility to deploy the report
Mention what method you can use to reduce the overhead of Reporting Services data sources?
Cached reports and Snapshots can be used to reduce the overhead of Reporting Services Sources.
Explain what is the difference between Tabular and Matrix report?
Tabular Report: Tabular report is the most basic type of report. Each column relates to a column chosen from the database
Matrix Report: A matrix report is a cross-tabulation of four groups of data.
Explain how would you store your query in an SSRS report or a Database server?
Storing SQL queries directly in text format in the data should be avoided. Instead, it should be stored in a stored procedure in the database server. The advantage is that the SQL would be in a compiled format in an SP and gives all the benefits of SP compared to using an ad-hoc query from the report.

Can we use data-grids for our report in SSRS?
We have an ASP.NET project that populates a data-grid. Using data-grid as my data-source for my report using SQL Server Reporting Services. Is this possible? The simple answer is no. However, nothing’s ever simple. A set of reporting controls was added in Visual Studio 2010 allowing you to report in a data-set, on data that was supplied by you. So, if you retrieved your data into a data-set, bound the data-grid to the data-set so it had data to display, you could then use that data-set as the data-source for the reporting controls. These are then client-side reports, not server reports though.
You want to generate a report that is formatted as a chart. Can you use the Report Wizard to create such a report?
No, the Report Wizard lets you create only Tabular and Matrix reports. you must create the chart report directly by using the Report Designer.
