Compiler Annotation Processor for Early Error Detection

The patent applies preliminary action by performing validation of input/output information and CRUD information during the compilation phase itself, rather than waiting for later testing stages. The annotation processor validates prerequisites (such as data existence and table record requirements) before code generation, thereby detecting errors early in the development cycle. This early detection mechanism prevents costly rework in integration testing and system testing phases.

The patent introduces an intermediary mechanism in the form of an annotation processor that acts as a mediator between the source code and the compilation process. This processor automatically validates input/output information and CRUD information, and generates necessary tables and data structures based on validated annotations. By automating this intermediary validation process, the system maintains high development efficiency while managing compilation complexity through structured, rule-based validation logic.

The patent applies self-service by enabling the compilation system to automatically verify specifications and generate necessary data structures without requiring manual intervention for each business process. The annotation processor self-validates prerequisites, automatically checks specification consistency across all business processes using a common process, and generates required tables and data structures autonomously. This automation maintains high specification accuracy while significantly reducing the manual verification time that would otherwise be required.
