Database is very important for the organization. The Develope process of database was divided into 4 stages: requirements analysis, ER design, relational schema, and create DBMS using SQL language. When creating ER design stage and then convert the diagram to a relational schema will need a long process and this procedure may be possible cause many human error. There are several applications to design the databases, such as Power Designer and Microsoft Visio. Both of two applications above can be used to draw the ER design, but can not directly convert into a relational schema. So Applications was made for Modeling Database, the specification are it can draw ER design than directly converting to relational schema. The application can handle half from all 4 proccess to design the databases. After implementation of the application, that applications can be used to draw the ER design, and then it can be converted into a relational schema, and then it can directly translate into SQL query and running in DBMS.idTeknik InformatikaInformatikaIlmu Komputer, Pengetahuan, SistemApplicationModelingDatabaseThesis
