Appl. No.:

13/272863

Inventors:

William V. Kehoe - Allston MA, US
Jerry L. Callen - Cambridge MA, US
Steven R. Frechette - Reading MA, US

Assignee:

Expressor Software - Burlington MA

International Classification:

G06F 17/30

US Classification:

707694, 707E17006

Abstract:

A method and system for developing data integration applications with reusable semantic types to represent and process application data. Methods include creating schemas to describe external data, creating semantic types to describe internal data, mapping schemas to semantic types, developing dataflows that configure input and output operations using schemas, mappings, and semantic types and all other transformation operations and functions based solely on semantic types, and executing dataflows defined in this manner.

Abstract:

Methods and systems for managing the development of data integration projects to facilitate project development and analysis thereof. Methods operate to manage the development, controlled, release, and analysis of a data integration project by receiving a project, associating the project with two superstates, and storing the project in both a source control system and a relational database according to the values of the two superstates.
