Put forward to set up according to the solution of the share data environment integrity of the terrace of J2EE, and discussed the key technique. This thesis put forward a set of share data environment project of integrity. Adopted the concepts such as comprehensive database and the data conversion environment etc.. In that project, the share data environment is divided in to be converted the environment and comprehensive applied environments by the data to constitute. The core of the data conversion environment is comprehensive database. Establishment comprehensive database needs to set up the mold and designs, comprehensive database realization, the data sample with conversion, the data clean, the problem data processing etc. The project' s adoption data cleans the latest technique in etc., resolving the data between the information islands interview and expand the applied problem.
