DBViewer: A Tool for Visualizing and Measuring Dependency Relations between Tables in Database

With the extensive use of the database and increasing complexity of its logic, how to visualize and measure the dependency relations between tables becomes a challenging task. However, ER graph can only tackle the situation of the partial view of whole database. For this reason, we proposed the methods for constructing a visualization and measurement tool for database-oriented software in this paper. Through an experiment analysis on a medium-scale database, it revealed that the degree distribution of table dependency graph roughly obeyed power law, and also validated the tool´s usability and effectiveness in practice.
