What is a Data Model?

A data model is a conceptual depiction of data objects and relationships between data objects and the rules. It is a representation that aids in creating conceptual models while setting relationships between data items. There are three types of data models:

  • Conceptual Data Model: This is a visual portrayal of database concepts and the relationship between the concepts.
  • Logical Data Model: These models establish the structure of data entities and provide a technical description of the data.
  • Physical Data Model: Used for database-specific modeling, physical data models provide schemas detailing how data will be stored in databases.

How to Select a Data Modeling Tool

There are a few important factors to consider when choosing a data modeling solution or vendor:

  • Understanding Business Needs: An understanding of your organization’s data modeling needs makes it easier to separate the essential capabilities from optional or “nice-to-have” capabilities. It is key to know your organization’s data consumption and processing practices.
  • Identify Features: Understanding business requirements makes it easy to choose required features with respect to your organization’s existing database structures. As such, the tools that should be in consideration are those that match your existing infrastructure and offer improvements to the value of your data.
  • Scalability: Due to the ever-increasing data needs of today, it is critical to consider the scalability of a solution. Can the solution evolve with time to keep satisfying your data needs? Can the solution be integrated with other systems without having to implement a new solution? Can the solution evolve with technologies such as machine learning?
  • Data Formats: Ensure the solution is compatible with your data types and formats, as modifications and data conversions may prove to be expensive and time-consuming.
  • Support: The complexity of data modeling may occasionally be overwhelming for users, so it is important to ensure the solution has great vendor support as well as an active user community.

ERBuilder Data Modeler

ERBuilder Data Modeler gives developers the ability to use entity-relationship diagrams (ERDs) to graphically design databases. The tool automatically generates many well-known SQL databases. Through an advanced visual data modeling environment, developers can easily deploy databases.

Key Differentiators

  • Intuitive Visual Data Modeling: ERBuilder’s brilliant user interface (UI) makes databases user-friendly and easy to design and model. With just a few clicks, users can create and design their models through the provided professional drawing tools.
  • Forward and Reverse Engineering: ERBuilder allows you to validate data models and generate data definition language (DDL) SQL scripts in a handful of clicks. You can also directly connect to an existing local or remote database to reverse engineer an existing database.
  • Deep Exploration of a Data Model: The data model browser module in ERBuilder allows full exploration of data structures extracted from large databases. An advanced search feature is integrated into the data model browser to give more flexible search competence.
  • Data Model Validation: You can check potential inaccuracies and ambiguities in the model you create using the checking control, creating and querying virtual data, and generating a web interface for your model.

Con: Large data models may suffer from long load times.

Pricing: A free edition is available for non-commercial use, and each of the four paid plans offer a free trial and demo. The Starter plan is priced at $49, Standard at $99, Professional at $149, and Enterprise at $199.

The Archi modeling toolkit is an inexpensive solution that targets enterprise architects and modelers of all levels. It provides an economical platform to users who may be starting out in the ArchiMate modeling language. Archi also targets users who seek an open-source, cross-platform ArchiMate modeling tool for their institution.

Key Differentiators

  • ArchiMate Modeling Language: Archi supports the newest version of the ArchiMate language, allowing users to comfortably create ArchiMate relations and elements in every ArchiMate view.
  • Fully Cross-Platform: Archi is written on the Eclipse Rich Client Platform in Java hence it is fully cross-platform. Users need not worry about sharing models across installations.
  • The Visualizer: Using a radial-tree graphic, Archi’s visualizer shows the elements of a highlighted model and its relationships with other model elements, allowing you to connect the dots between model elements.
  • Sketch View: Sketch view allows you to brainstorm and sketch your ideas using “stickies” to rapidly design and create models without worrying about language technicalities.

Con: The UI is not intuitive, and the directory may frustrate users.

Pricing: Archi is an open-source tool. Although, they do welcome donations to help maintain Archi.

erwin Data Modeler

erwin Data Modeler by Quest is a data modeling tool for finding, visualizing, designing, standardizing, and deploying high-quality enterprise data assets. It is defined by discovery and documentation of any data from any source for clarity, consistency, artifact reuse across large-scale data integration, and business intelligence initiatives among others.

Key Differentiators

  • Customizable Modeling Environment: With erwin Data Modeler, users can automate time-consuming and complex tasks to improve the effectiveness of database design, maintenance, standardization, and deployment across users’ database platforms.
  • Roundtrip Engineering: erwin Data Modeler supports comprehensive enterprise database management through forward and reverse engineering of database code and model exchange.
  • Out-of-the-Box Bridges: To facilitate metadata exchange and transformation from different modeling environments, metadata exchange formats, and data management platforms, erwin Data Modeler offers out-of-the-box bridges.
  • Model and Database Comparisons: erwin Data Modeler has a Complete Compare feature that compares items with each other, shows differences, allows selective upgrades, and generates ALTER scripts when necessary.

Con: The UI may seem dated and may be complex to navigate.

Pricing: A free trial is available. Contact the erwin Data Modeler pricing team for questions on pricing or a quote for your unique requirements.

IBM InfoSphere Data Architect

IBM InfoSphere Data Architect is a data design solution that covers every section of the data design process. It helps users discover, standardize, model, integrate, and relate vast and distributed data assets all through the enterprise. This collaborative enterprise data design and modeling tool simplifies and accelerates integration design for master data management and business intelligence.

Key Differentiators

  • Native Data Querying: Through analyzing and examining underlying data, InfoSphere Data Architect unearths the structure of heterogeneous data sources. Users enjoy a good understanding of the detailed properties of every data element.
  • Logical and Physical Data Modeling: Users can create logical data models that describe the relationship between data models and describe how an enterprise seeks to collect data. These logical models can then be transformed into new physical data models.
  • Import and Export of Constant Mappings: The tool has an import/export mapping model wizard that allows users to automatically export and import constant mappings found within mapping models to and from a CSV file.
  • Integration with Related Products: With InfoSphere Data Architect, you can build models for IBM Informix, Oracle, IBM Db2, Microsoft SQL Server, Sybase, MySQL, and Teradata source systems.

Con: Logical data models cannot be exported.
