Partially embedded database and an embedded database manager for a control system

摘要

A method for creating a compressed database includes a step of receiving a data input file. The data input file defines a first set of data fields to be included in the database and includes a set of data elements to be included in the database. The method also includes identifying a second set of data fields in the data input file that are designated to contain a Boolean element, the second set of data fields being a subset of the first set of data fields. The method further includes defining one or more new data fields for collectively storing the Boolean elements, and modifying the first set of data fields to eliminate the second set of data fields. The method also includes generating a catalog that defines an arrangement of the first set of data fields, wherein the arrangement includes the one or more new data fields for collectively storing the Boolean elements.
