Activity chaining is a feature that allows users to complete multiple tasks in a row without returning to their task list. However, activity chaining can also have some drawbacks, such as increased memory consumption, longer transaction times, and reduced user feedback. Therefore, some actions can be taken to make the process model more efficient, such as:

Shorten long process chains by combining transactions into the smallest number of nodes. This can reduce the memory footprint and the database load of the process model.

Avoid chaining system nodes like Integrations. These nodes can have unpredictable execution times and can cause timeouts or errors if chained. It is better to use asynchronous integrations or message events to decouple the process flow from external systems.

Move transactions that can be done asynchronously outside of the chain. This can improve the responsiveness of the process model and allow parallel processing of independent tasks.

Therefore, the correct answers are B, C, and D.

Performance Best Practices

The database object that should be used to create a virtual relation in a database to query the data is a view. A view is a searchable object that is defined by a query. It does not store any data but retrieves data from one or more tables at run time, creating a virtual table and returning the data in the defined format. It is created using joins, filters, aggregations, or other SQL operations. A view can be used to simplify complex queries, provide security, or enhance performance. Therefore, the correct answer is D.

Views

 Object security settings can be changed in bulk in the application security summary and the compare and deploy tool. The application security summary provides a centralized view of the security role maps for all objects in an application. You can filter, sort, and edit the role maps from this view. The compare and deploy tool allows you to compare objects between two environments and deploy changes from one environment to another. You can also edit the role maps of the objects before deploying them. References: Application Security Summary, Compare and Deploy Tool
