Answer / Santosh Prasad

1. XML (Extensible Markup Language) is a markup language that defines a set of rules for encoding documents in a format that is both human-readable and machine-readable. It's used for data exchange between different systems, especially on the web.
2. A render variable is a named value or expression in Cognos that gets replaced with actual values during report execution. A conditional block is a part of a report that executes based on certain conditions.
3. In Cognos, a link refers to a navigational element that takes you from one report to another, while a segment is a grouping or partitioning of data within a report.
4. Conditional layout in Cognos refers to the ability to format report elements differently based on specific conditions, such as when a value exceeds a certain threshold.
5. Detail filter and summary filter are used in SQL to filter data at different levels. A detail filter is applied before grouping or aggregating data (on the detail level), while a summary filter is applied after grouping or aggregating data (on the summary level).
