Access Points FAQS

1. What is an Access Point in data flow?

• An Access Point is a marker or node that indicates where data is transferred between two execution units. It is represented by a round icon and is created on the target side of a pair of execution units.

2. How does an Access Point work?

• An Access Point controls the flow of data from one execution unit to another. It ensures that data is passed correctly through the execution units in the workflow.

3. How is an Access Point created?

• An access point is automatically created on the target side when data moves from the source side to the target side between two execution units. It can also be manually adjusted using Execute On Hint in the logical diagram to specify a different location.

4. Can I move the Access Point to the Source Side?

• No, you cannot move an access point node to the source side. The access point can only exist on the target side of the execution units.

5. What happens if I drag an Access Point to an empty area?

• If you drag an access point node to an empty area of the diagram, a new execution unit is created between the original source and target execution units. This creates an additional processing step in the data flow.

6. What are Loading Knowledge Modules (LKMs)?

• Loading Knowledge Modules (LKMs) are responsible for managing how data is transferred between execution units. They ensure that the right data is loaded and processed between the source and target execution units.

7. Can I change the execution location of an Access Point?

• Yes, you can change the execution location using the Execute On Hint in the logical diagram to suggest a different execution location than the default target side.

8. What is the purpose of an Access Point in execution workflows?

• The access point is essential for controlling and ensuring that data moves smoothly from one execution unit to another. It helps manage how data is processed and moved through different stages of the workflow.

9. How do Access Points relate to execution units?

• An execution unit represents a processing step in the data flow. The access point connects these execution units by managing how data is transferred between them.

10. Can I delete or modify Access Points?

• Yes, you can modify or delete access points by adjusting the diagram or the execution units involved in the data flow. However, the access point is automatically generated based on the flow of data, so manual adjustments may be necessary.
