Schema and Data Conflict Resolution Across Distributed Graphical ASN.1 Databases.
NAVAL POSTGRADUATE SCHOOL MONTEREY CA
Pagination or Media Count:
Recently, most large corporations, including the Department of Defense and the Department of the Navy have seen a dramatic proliferation of incompatible databases and their associated database management systems. Sooner or later, these organizations discover the need to integrate the data in these incompatible databases. One solution to this problem is the use of mark-up languages like Abstract Syntax Notation One ASN.1 as a standard format for representing these databases and output reports and thus facilitating their integration. A main requirement of this integration approach is the ability to correctly identify and resolve the semantic conflicts that arise in the marked-up databases and outputs of software tools before any integration can take place. This thesis addresses this issue by introducing a systematic approach for identifying and resolving semantic conflicts for these databases and developing a prototype tool which aids in this resolution. We hope that this tool will greatly aid in the efforts of integration and manipulation of ASN.1 databases.
