SSRS Architecture is a three-tier architecture consisting of a client, application server, and database server.

• Client sends a request to the application server

• Application server processes the request and retrieves data from the database server

• Data is then sent back to the application server and rendered in the client

• Report Server manages the report processing and rendering

• Report Manager provides a web-based interface f

There are two types of facts: objective and subjective.

Indexes are used to improve database performance by allowing faster data retrieval.

• Clustered index: sorts and stores data rows in the table based on their key values.

• Non-clustered index: creates a separate structure that includes the indexed columns and a pointer to the data row.

• Unique index: ensures that the indexed columns contain unique values.

• Covering index: includes all the columns needed to satisfy a query, so th...read more

Merge combines two sorted datasets into one, while Union All combines two datasets without sorting.

Conditional Split Transformation is a data flow transformation in SSIS that routes data based on specified conditions.

• It is used in SSIS to split data based on conditions

• It has one input and multiple outputs

• Each output has a condition that determines whether the data is sent to that output

• It can be used to filter data, route data to different destinations, or perform different transformations on data based on condition
