After the database engineer has created an effective physical model, the tool can be used to generate a SQL Data Definition language script, which can be directly executed on the RDBMS environment or saved to a file.Both editors can create customizable entries and ensure essential rule enforcement for data management. This tool includes an abbreviation/naming directory called Naming Standards Editor and a logical RDBMS data type mapping facility named Datatype Standards editor.If model changes are targeted, the agency can generate a script to make these changes. The tool also compares and automates bidirectional synchronization of models, scripts, and databases.This tool also supports the naming of tables and columns, user-defined data types, primary keys, foreign keys, alternative keys, and the naming and definition of constraints.This tool also supports the combination of physical and analytical models, other than entity type, and attracts logical names and descriptions, logical domain, and data types, among others. This tool allows for creation of purely logical models, from which physical models may also be created.Some other features of the tool include the following: Computer Associates then added this tool to their AllFusion suite under AllFusion ERwin Data Modeler, later named CA ERwin Data Modeler. Created by Logic Works, this tool was acquired by Platinum Technology in 1998 and was later obtained in 1999 by Computer Associates. Based on the IDEF1X method, this tool supports diagrams displayed with information engineering notation.

CA ERwin Data ModelerĪnother software tool for CA ERwin Data modeling is used for developing custom-made information systems, including data charts and databases for transactional systems, besides data requirement analysis and database design. Some of the enterprise architecture frameworks that BiZZdesign supports include ArchiMate, DYA framework, Pragmatic Enterprise Architecture framework, and Tapscott, among others. In addition, it was recognized as a unique enterprise architecture tool by Garter and Forrester in 2012. This data modeling tool intends to offer clients a high-value enterprise architecture data modeling tool that can be controlled by business management.

Released in 2004, BiZZdesign Architect was developed by BiZZdesign based on the ArchiMate project results. By supporting modeling, visualization, analysis, and documentation of enterprise architecture from multiple viewpoints and various views, BiZZdesign Architecture also supports automatic data collection and data import from office applications. BiZZdesign ArchitectĪ visual data modeling and design tool, BiZZdesign Architect, is used by Enterprise Architecture to support the application of several enterprise architecture frameworks, including ArchiMate and TOGAF.

The 2.1 version of the tool is free and supports sketches, cross-platform, and an open-source platform. By providing an open-source reference implementation of ArchiMate, Archi is presently one of the tools used to implement the Open Group ArchiMate Model Exchange File Format. This data modeling tool supports the ArchiMate 2.1 modeling language, a technical standard created by the Open Group. Initially funded by Jisc between 2010-2012, Archi was a part of the national project that helped to support a program of Enterprise Architecture in the higher education sector of the United Kingdom. The last step involves the transformation of an analytical data model into a physical data model.Ī free and open-source visual modeling and design tool, Archi is used to create models and modeling sketches. Multiple logical data models maybe are needed to implement a single conceptual data model. Post this the conceptual model is converted into a logical data model that documents the structure of data, which is then implemented into databases. Initially, the data requirements are recorded as a conceptual data model, a set of technology-independent specifications used to talk about the initial conditions of data. Three different data models are produced, from data requirements to database creation.

The process, therefore, requires the close and active collaboration of professional data modelers, stakeholders, and prospective users of the information system. That is why it is used to define and analyze data requirements necessary for supporting the business processes that are a part of companies’ information systems. Today, data is an essential aspect of business and brands worldwide. This is done by applying formal data modeling techniques. In software engineering, data modeling creates a data model for an information system.
