PROLOG is well–known for its qualities in the development of sophisticated rule systems.
We use Prolog’s declarative features and its backtracking mechanism for code analysis, refactoring, and tuning.īusiness specifications – that formerly only supported IT development – increasingly become business configurations in the form of rules that can be loaded directly into IT solutions. We trace the values of variables that contribute to a query string backwards to predict the values of contributing program We do this without using a debugger or a virtual machine technique instead, Here, we show how to derive the strings of dynamic Sql statements directly from the Java source code. This should be done mostly automatically, sinceĬhanging software manually is error-prone and time consuming.įor determining the Sql statements that access the database, we can either look at the database logfile, an audit file, or at the Java source code If the underlyingĭatabase schema of such an application is subject to refactoring or database tuning, then the Sql statements in the embedding Java program need to be adapted correspondingly. In this paper, we analyse Java source code of embedded database applications by means of static code analysis.
