Data Sets are combinations of related CONTACTS, COMPANIES, and TASKS linked together. Create sets for any category entries, such as “CONSTRUCTION” to operate related tasks and “DISTRIBUTORS” for contacts of distributors. Do not need such functionality? Leave everything with no sets and it will work just fine.
Structure your contacts, companies, and tasks. Data Sets are the easiest way to differentiate work fields. Thus, you can keep all data within a single database without confusion. Data Sets are fully isolated from each other, so you can even have sets like “Home” and “Work” in the same file for convenience.
