Using a packaged data model, projects take less time and cost because...

a) There are fewer entities to model
b) Relationships are pre-defined
c) Data redundancy is reduced
d) All of the above

Answer 1

Using a packaged data model reduces time and costs by having fewer entities to model, pre-defined relationships, and reduced data redundancy.

Step-by-step explanation:

Using a packaged data model, projects take less time and cost because of a combination of factors. When using a pre-defined data model, the entities have already been outlined, which means there are fewer entities to model. Additionally, because the relationships are pre-defined, much of the complex groundwork that comes with designing a database structure is already complete. Lastly, such models are designed to minimize overlap in data storage, hence data redundancy is reduced, improving efficiency in data management and potentially lowering storage costs.
