Which of the following is a valid Bendix token?
Answer- Current User
You are creating a micro flow where you have a Change Object
activity. The change is dependent on a lot of checks and
decisions (but, whichever choice, the change always happens).
What is the best way to model this micro flow?
Answer- Use Decisions, but place them in a sub-micro flow to
determine what the new value should be, and then use the return
value of that sub-micro flow in the Change Object activity.
You need to determine what day of the week it is. What is the
easiest way to do this?
Answer- Use the format DateTime function to achieve this.
,What is the best approach to retrieve an object over association,
while also checking whether the association exists?
Answer- Use a decision to first check whether the association
exists. If it does, retrieve the associated object.
Which of the following statements about lists is true?
Answer- A list can have, among others, the following origins: a
retrieve action, the creation of a new list, and the result of an
input parameter.
You have to determine how many customers are in the database
and find that there are at least a couple thousand. How do you
handle this?
Answer- Retrieve all the customers at once and use an aggregate
list activity to count them. Because this is an optimized query on
the database, it will be very light and safe to use, even for big
lists.
What does the List Operation tail do?
Answer- It grabs all elements in the list except the first element.
,When would you typically use a List Operation?
Answer- - To avoid complex XPaths.
- When you are working with objects that only exist in memory.
- When creating report data to view in chart widgets.
You've created a micro flow that contains a loop. This loop uses
the same logic as a micro flow you have already built, so you
decide to call this micro flow as a sub-micro flow inside the loop
so that you can reuse the functionality. What do you check
before doing this?
Answer- - If there are retrieve activities in the sub-micro flow
for data you already have available in the main micro flow,
check whether it can be passed along as an input parameter
instead.
- You make sure that there are no commits in the sub-micro
flow, since it is not good for your application to commit inside
of a loop.
- If the sub-micro flow uses a return value, you check whether it
is really needed.
, Your application contains a micro flow that calls three sub-
micro flows. Each of these sub-micro flows does a retrieve from
the database on the same entity. Should you change this?
Answer- Yes, you should do the retrieve in the main micro flow
and then pass it along to the three sub-micro flows as an input
parameter.
Which statement about rules is true?
Answer- A rule can only be called from within a decision.
What is a good reason to use a sub micro flow?
Answer- - To use it as a 'get or create' micro flow.
- To reuse the same bit of logic in multiple micro flows.
- To increase readability of large micro flows.
To which of the following errors types does the built-in
consistency checker in the Modeler alert you?
Answer- Technical issues in your model.
