Data Modeling ensures consistency in naming conventions, default values, semantics, and security while ensuring the quality of the data.

Plus, the people behind the system are great to work with. I developed an add-on tool that lets my students design their models, then port the design to my tool where it evaluates their model or as my students say, "Insults their model" giving them instant feedback.

I have been as impressed with the team as I have the tool itself. I am glad to have been on the beta journey with them and watch this product grow in it's capabilities. We have been using it to help rapidly design and socialize data models internally and with our customers. They have been extremely receptive to our feedback and incorporated changes into their product.

Creating databases through diagrams is the simplest way to create a database.

With tools that can import data from external databases, creating diagrams is easier than ever before. If you need multiple users to work on diagrams then adopting a tool with collaboration capabilities is a must. Define the purpose and boundary of the database Gather all data labels for the system Group the labels by type Open an ERD diagrammer Create an entity for each group Create attributes within each entity and name it with the relevant data label Identify candidate keys in each group Find a unique key — if none exists generate an attribute Normalize the groups so that each attribute in a group is dependent on the key, the whole key, and nothing but the key.

Connect entities together with relationships Add foreign keys to entities where necessary If any many-to-many relationships exist, create an intermediate Entity to break that relationship down.

A relationship is shown in an ERD as a line between two entities. There should be one attribute in one table, called a foreign key, that will contain values that match those in the primary key of another entity. The relationship line links those two attributes together. This site uses Akismet to reduce spam. Learn how your comment data is processed. Comparitech uses cookies. More info. Menu Close.
