Personal digital assistant for storing/processing relational databases, comprises copying field key format information from first to second table descriptors and establishing links between tables

摘要

The personal digital assistant has a microprocessor (1), read only memory (2), user memory (3a) and data acquisition means (5,6). During database construction data defining field key formats is copied from a first table descriptor to a second table descriptor such that each field key has the same format in the two tables. A linkage is then made between the two tables to identify identical memory space keys
