If nothing else, erwin is sure to understand data and data modeling. The erwin Data Modeler has been around for a good 30 years. The Physical Data Model – to describe the database-specific implementation of the data model.The Logical Data Model – to define the structure of the data elements and set the relationships between them.The Conceptual Model – to establish the entities, their attributes, and their relationships.Conceptual model vs Logical model vs Physical modelĭata modeling usually contains three layers: Data modeling tools worth their salt will not only draw pretty pictures but also integrate directly with your databases.īut before we get to our list of top ten data modeling tools you should know, let’s quickly recap how data modeling works. The process of defining what data needs to be collected and how it should be stored is data modeling.ĭata modeling can be done with any UML editor or even pen and paper, but there are a plethora of tools specifically designed for data modeling. It doesn’t matter if it is an SQL or NoSQL database data can be stored and collected in many ways. Data models are often designed in the form of a UML diagram. Toad Data Modeler models can be synchronized with physically existing databases using various tools, such as Reverse Engineering, Model Update, Change Script Generation and Model Merge.A data model is a visual representation of data specification.

Models can be verified and list of errors, warnings and hints can be displayed as a result of model verification process. The verification can be customized to a degree by enabling/disabling verification rules. The model integrity can be verified at any time, the Model Verification tool displays errors, warnings and hints. Models can be also exported to Microsoft Excel (XLS) and CSV files. The ER diagram of a model can be exported as an image in BMP, JPG or PNG format. It is also possible to generate output based on XSL transformations - XML, TXT, CSV etc.

Model documentation - Toad Data Modeler can generate model reports in HTML, RTF and PDF format. SQL/DDL files can be reverse engineered as well for some of the supported database platforms. Toad Data Modeler support multiple connection methods for each supported database platform, such as native connection, ODBC, ADO, etc.
Reverse engineering - Existing databases can be reverse engineered into Toad Data Modeler models and displayed as entity relationship diagrams (ERD).

The resulting script can be also modified by writing Before Script/After Script for specific objects - SQL code which is placed before/after the object CREATE statement in the final script. It is possible to choose which object types should be generated as well as customize the generated script using a variety of option. SQL/DDL code generation - Complex SQL/DDL code for created models can be generated automatically for all supported database platforms. This tool supports various database specific items and therefore it is necessary to select a target database system for a physical ERD. Toad Data Modeler allows users to create logical, physical and universal entity relationship diagrams (ERD) - models. Visual creation of Entity Relationship Diagrams

Quest Software was acquired by Dell as of September 28, 2012. It was previously called "CASE Studio 2" before it was acquired from Charonware by Quest Software in 2006. Toad Data Modeler is a database design tool allowing users to visually create, maintain and document new or existing database systems.
