The integration or heterogeneous In-service training data offers possibilities to manually and automatically draw tip new information of professional human resources, which are not available when using only a single data source. Furthermore, It allows for a consistent representation and the propagation of updates from one data set to the others. However, different acquisition methods, data schemata and Updating cycles of the content call lead to discrepancies in professions and expertise accuracy and correctness which hamper the combined integration. To overcome these difficulties, appropriate methods for the integration and harmonization of data from different Sources and different types are needed In this Study, twenty-five databases were Integrated into one national level database. More than 220,000 K--12 teachers' in-service training data were collected through out this heterogeneous databases Integrating project A untried subject-category was Introduced based upon both the teaching professions and administration professions so as to absorb all twenty-five Sources. The integrated feasibility was evaluated according to the efficiency and correctness.
