What is single object and reusable objects in Data services? |
|
Answer» Reusable Objects − Most of the objects that are stored in repository can be reused. When a reusable objects is defined and save in the local repository, you can reuse the object by creating calls to the definition. Each reusable object has only one definition and all the calls to that object refer to that definition. Now if definition of an object is changed at one place you are changing object definition at all the places where that object appears. An object library is used to contain object definition and when an object is drag and drop from library, it means a new reference to an existing object is created. Single Use Objects − All the objects that are defined specifically to a job or data flow, they are called single use objects. Example-specific transformation used in any data load. |
