A method and system unifying existing data of a target industry from existing sources of the data by designing a data model by applying varying data integrity methods to define characteristics, features and/or functions of items in the target industry as data elements, electronically reading, parsing and transforming data from existing electronic data sources of the target industry to input to the data model, designing user interfaces to the data model, the user interfaces corresponding to user segments of the target industry, and dynamically maintaining normalization of the data model according to the varying data integrity methods during any type of access to the data model by the user segments. A data entry access to the data model comprises dynamically constructing search indexes, each search index defined as a unique data field and a text searchable concatenation of other fields' data in any given data table of the data model.
