Visible diagram area and Zoom level slider.

That will open a new Diagram Editor window.īefore we continue any further, let’s take a moment to familiarize ourselves with the Diagram Editor’s interface: In the New Model window, choose Conceptual as Model Type.

To create a conceptual model, select File -> New Model from the main menu.

Our model will contain a sales entity with three peripheral ones for dates, stores, and products. The Star Shema gets its name from the resemblance of the diagram to a star. The model that we will create depicts a Star Schema, whereby you have a central data entity, surrounded by several peripheral ones. There are two ways to create a new model in Navicat Modeler: you can create it from scratch or generate it from an existing database. It may have many diagrams associated with it, which each depict the entire schema or a part thereof. Creating a New Conceptual ModelĪ model is a conceptual, logical, or physical representation of a schema. To learn more about it, see the MySQL Collaboration in the Cloud article. * Navicat Cloud is beyond the scope of this article. You can then access and save models to either the local computer or Navicat Cloud*: Upon successful logon to Navicat Cloud, the Welcome window splits into two parts: your local Computer and Navicat Cloud. There is also a Sign In form for Navicat Cloud. It contains several commands, including one to create a new model, open an existing model file, and links to recent models. Upon launching Navicat Data Modeler, a Welcome window appears. Please refer to the documentation for more specific information. On your O/S, procedures and appearances may differ slightly.

The trial version of the Navicat Data Modeler may be downloaded from the company’s website for the Linux, Windows, and Mac operating systems. Navicat Data Modeler offers one additional feature: being fully integrated with Navicat Cloud, it enables you to synchronize your model files and virtual groups to the cloud in real-time. Likewise, using a process known as reverse engineering, new Entity Relationship diagrams may be created from existing database structures. All structural elements from entity relationships, table/view attributes and columns may thusly be created and managed from within the model. In addition to simplifying the creation of data models, GUI tools can link models to tables and/or views so that changes to a model may be deployed to database structures directly. Navicat Data Modeler supports three standard model notations: Crow’s Foot, IDEF1x and UML. Rather than write them yourself, you create, modify, and design your models within object designers, which generate the DDL statements behind the scenes.

GUI Applications like the Navicat Data Modeler automate the writing of Data definition language (DDL) statements. How a GUI Application Simplifies Model Generation A physical database model shows all table structures, including column names, column data types, column constraints, primary key(s), foreign keys, and relationships between tables.

Physical: Physical data model represents how the model will be built in the database.

Logical: A logical data model describes the data in as much detail as possible, but without regard to how they will be physical implemented in the database.

Conceptual: A conceptual data model identifies the highest-level relationships between the different entities.

What is Data Modeling?ĭata modeling involves the formalization and documentation of data entities used within a business or other context as well as the identification of the relationships between these data entities.

In today’s tutorial, we’ll learn how to design, implement, maintain, and synchronize MySQL database schemas using just such an application – the Navicat Data Modeler. Once completed, your database will better meet your needs and can easily accommodate future changes.Īs in all aspects of database development and management, specialized software has emerged to make the process much easier to accomplish. Therefore, investing the time to apply the principles of good design should be a high priority. A proper database design is essential to achieving your goals in working with a database, whether they prioritize rapid information retrieval, efficient storage, or some combination of both.
