How to subdivide the data elements
A name that’s divided into first and last names
An address that’s divided into street address, city, state, and zip code
Description
- If a data element contains two or more components, you should consider subdividing the element into those components. That way, you won’t need to parse the element each time you use it.
- The extent to which you subdivide a data element depends on how it will be used. Because it’s difficult to predict all future uses for the data, most designers subdivide data elements as much as possible.
- When you subdivide a data element, you can easily rebuild it when necessary by concatenating the individual components.
