The Challenge

The project goal was to design and implement a fast, replicable query database system for the client’s ISP platforms. The new AADB system was intended to replace an outdated AA0 tool and provide advanced performance and functionality. The new system also had to solve several major problems existing in the AA0 software, including restricted scalability and replication features, absence of documentation and low efficiency.

The Solution

The newly developed AADB system consists of several AADB servers (nodes) arranged in a tree with a special root. Each node serves as a query server for AADB clients; the root node is responsible for processing update requests. During the replication process the information propagates through nodes from the root down to the leaves. Each AADB server has a database, possible connections to parent and child nodes, and an interface for client queries. The server’s design allows simultaneous processing of client requests as well as peer updates.

Tools and Technologies

UML, "REAL" proprietary CASE tool; ANSI C and Tcl programming languages; GNU compiler & tools, including 'Configure' and 'Bison;' SleepyCat DB; RC4 cipher, MD5.
