Building and search system for a large-scale DNA database

The authors newly developed a hierarchical relational schema for effectively building, integrating, and searching the DNA database on the relational database management system, SYBASE, at DDBJ. The scheme is named the 'DDBJ-schema'. The schema allowed the authors to implement window interfaces to easily build the DNA database. The DNA database built in the GenBank-schema using AWB is converted into the relational format of the DDBJ-schema using a restructuring tool at DDBJ. A virtual-structured SQL-programing method is proposed to implement the restructuring tool. The method is developed through the 'view' function and the control flow language (CFL) of SYBASE. Moreover, the authors also proposed two methodologies by which one can execute these software tools on UNIX based workstations connected by a computer network.<
