Hi @Sangam
We Use Structures and Records to create compound Data Types.
I can explain the Structure and Record data type some brief as per my knowledge.
Structures
i) When you need to store multiple entity data's or two store temporary purpose till you are hitting the server to store the database. we use structures.
ii) when you need to combine the different entities data like
Example:
I'm having an entity of school and having different 10 attributes and another entity College having 8 attributes, But when I want 3 attributes from school and 6 attributes from college just to store purposes or to display purposes I use the Structure.
Regarding Structures I'm attaching one OML, Please find the attachment for your reference If any Queries Please comment or connect through the profile.
Record Data Types
Where we want to find and review places of interest, we want to return basic information about a Place using a REST API method.
The information to return about each place is the Id, the name, and the average rating. The data is stored in the Place Entity an Review Entity.
The data type that we need to assign to the output parameter will only be used we will use a Record:
Yes, I won't provide any tutorials, But just go through those or Documentation .
