As　the　development　of　computer　technology,　the　information　integration　begins　to　be　the　key　part　of　the　enterprise　information　system　development.　The　key　problem　of　the　heterogeneous　database　information　integration　is　the　detection　and　resolution　of　data　confliction.　According　to　the　integrating　processing,　a　classifying　layer　model　of　data　confliction　and　the　integrative　resolution　of　those　kinds　of　confliction　were　proposed.　Due　to　the　attribute　matching　in　heterogeneous　database　semantic　integration,　attribute-space-match　algorithm　is　presented　according　to　the　idea　of　establishing　attribute　space.
