Data modeling tools are useful in software development and in database design. Some advanced modeling tools available in the market go beyond the data modeling process and allow the generation of source code or DDL scripts for RDBMSs based on the modeled schema. This work presents OMT-G Designer, a web tool for modeling geographic databases using OMT-G, an object-oriented data model for geographic applications. The tool provides various consistency checks on the integrity of the schema, and includes a function that maps OMT-G geographic conceptual schemas into physical schemas, including the necessary spatial integrity constraints. The tool was developed using free software and aims to increase the practical and academic uses of OMT-G, by providing an open and platform-independent modeling resource.
