Crow’s Foot Notation in Vertabelo

Various ERD notations follow different styles for entities, relationships, and attributes. Usually there isn’t much standardization between them, so notations bear little resemblance to each other. Among the plethora of ERD diagram notations, crow’s foot notation is definitely the most used. In this article, we’ll investigate its components within the Vertabelo database model. Before we start looking into crow’s foot notation, we must understand that there are various levels of Entity-Relationship diagrams: conceptual data model – an overview of what should be included in the general database model.

Tip #24 – How to name a version of the model

Vertabelo offers you a feature to assign tags to particular versions of your model. It may be used, for example, to match the versions of your database model with the versions of your application. To assign a tag to the current version of the model, click Set tag in the options menu: Enter a tag name and click Set tag. Now, this version is tagged.

Tip #23 – How to create a reference to an alternate key

Sometimes, you want the reference between two tables to reference an alternate key and not the primary key. Here's how you can do it in Vertabelo. In this example, we want to model cars and their owners using owner and car tables. The car table has an alternate key consisting of the vin column: We want the owner table to refer to the car table, but using the car table’s alternate key.

Tip #22 – How to identify problems with my model

Vertabelo has a built-in mechanism of live validation that checks your model all the time and gives you hints on how to improve it. Every error, warning or tip is flagged by a dedicated icon that you cannot fail to notice. Within your workspace, the problems are indicated in two places. In the left panel you can review all problems found in your model, while on the right side you’ve got information on problems detected in the currently selected object only.

Tip #21 – How to quickly find a table in a diagram

Do you know the quickest way to find a single table even in the largest diagram you can imagine? The answer is to double click the table’s name in the navigation tree! In the Model structure panel on the left, you’ve got a navigation tree with groups of all elements used in your diagram, including database objects such as tables, references and views, as well as other subsidiary elements like subject areas and text notes.

Tip #20 – How to configure Vertabelo printouts

Sometimes you may want to export your database model to a PDF file, especially for documentation purposes. It often happens that your diagram is larger than the default page size set in Vertabelo. If that's the case, you should configure the printout options in the Format section. Make sure that no element in your diagram is selected. Go to the Model properties panel on the right and expand the Format section which provides some basic formatting parameters.

24 Database Modeling Tips for Vertabelo

In our previous Tip #16 and Tip #17 you could have learned that using table shortcuts makes it easier to create a well-laid-out database model. Do you know that references between shortcuts may be shown in the diagram too? Let’s go back to our example from Tip #16. Assume that we have already created all necessary subject areas. Now, we want to put shortcuts of all purchase-related elements in the Purchase subject area.

Tip #17 – Drag a table from the navigation tree and drop it in your diagram to create a shortcut

In our previous Tip #16, we showed you how to create shortcut tables using copy and paste. But did you know that you can create a shortcut of a table with only one move of your mouse? Just find the table in the navigation tree and then drag and drop it in the desired place in your diagram. Let’s assume that you want to create a reference line between two tables that are located quite far away from each other in your database diagram:

Tip #16 – Can I put the same table in the diagram twice?

Yes, you can! Shortcuts combined with subject areas might completely change your approach to database modeling. They allow you to make your diagram much more structured, logically divided and readable. Let’s look at an example. At the beginning, we have a really standard database model for a shop. Open your database model in Vertabelo: Now, we’re going to use subject areas in the model. To start, let’s put the whole model in a subject area:

Tip #15 – How to visually group tables and organize large database models using subject areas

Large models often happen to be quite messy. Using subject areas, you can improve the readability of your model and make it easier to work with. The idea behind subject areas is to group tables inside them according to their purposes – it allows you to create some logical structure in your model and makes navigation through it more natural. Open your database model in Vertabelo: To create a subject area, choose Add new area from the toolbox or press 7 on your keyboard:

Tip #14 – How to create a model preview link and embed the model in a website

When it comes to sharing things like documents or photos with other people, sending files to each other is becoming less and less common – we usually prefer to send links. They are quick, convenient and neither use up disk space nor make a mess in our file system. At Vertabelo, we know how inconvenient it can be to send files and that’s why we created public links for models.

Tip #13 – How to export selected tables as an image

Probably you have already generated a PNG image for your model, but did you know that the image may be generated for chosen elements only? Open your database model in Vertabelo: Select the desired objects with Ctrl + Click or using Select area from the toolbox: Click Export model as PNG image in the top toolbar: And this is your PNG image:

Tip #12 – The quickest possible way to create a new column

From our previous Tip #2 you could learn how to move between columns in your table using just arrow keys. Now, we will show you how to use the Down arrow to create one or even more new columns. Probably, this is the fastest way of creating new columns in this part of the galaxy. You really have to learn this. Open your database model and select the table in which you want to create a new column.

Tip #11 – Vertabelo reports that my data type is not supported. What can I do?

Sometimes you may want to use a data type that is so new that Vertabelo doesn’t recognize it. In such cases, the application displays a warning that the data type is not supported. If you find these warnings too distracting, you can turn them off. In this post, we will show you how to do it. Let’s take a look at the following example. Assume that you have a database model for MySQL 5.

24 Database Modeling Tips for Vertabelo

This one is frequently asked on our support: “In the data types panel, I can’t find the data type I need. Does this mean I cannot use it in Vertabelo?” Of course, you can. Vertabelo will never let you get stuck in a data type dead end. Even if the type you need is not listed, it doesn’t mean you cannot use it. Data types you can find under the button are just the most popular ones.

Tip #9 – How to create multiple references between two tables

Relationships in the real world may not be as easy as we would like them to be. Sometimes we want to model a situation where one table is refering to the other more than once. Luckily, with Vertabelo, this is a piece of cake. Let’s say we want to model a rental agreement between two people: landlord and tenant. In this situation, the rental_agreement table would need to refer to the person table twice – first for the landlord and second for the tenant.

Tip #8 – Setting Your Own Names for Primary Key

Sometimes the naming convention you use requires a specific pattern for the primary keys’ names. That’s why you may want to set your own names for each primary key in your database model instead of using default ones. Go on reading to get to know how to do this in Vertabelo. To give your own name to a primary key, select the table that contains the primary key you want to name:

Tip #7 – How to include comments in SQL script

You can comment on your database objects (tables, columns, views) in Vertabelo. You can also include this metadata in your database, where it can be accessed by your SQL developers or DBAs. Here’s how you can do it. Go to your database model: Click SQL generation settings in the Model properties panel on the right: Check the Include comments for database objects option: Let’s try out how it works.

Tip #6 – How to Create a Multicolumn Primary Key

Primary keys may contain more than one column. Multicolumn primary keys are frequently used for junction tables, which are used to model many-to-many relationships. Select a table: In the Table properties panel on the right, check all the columns that you want inside the key: Now, you have a multicolumn primary key created: You can check out your SQL code by clicking the SQL preview button in the top right corner:

Tip #5 – How to quote table names in generated SQL script

Sometimes, you want all identifiers in your SQL script to be quoted. For example, you want them to have a particular case. Luckily, Vertabelo allows you to quote all SQL identifiers in your generated script to prevent you from any SQL name conflicts. Go to your model: Click the SQL generation settings tab in the Model properties panel on the right: Check Quote all SQL identifiers:

Tip #4 – How to Make a Column Unique

Sometimes there are columns in a table that don’t belong to primary key, but are still unique. To mark them as a unique, you have to create an alternate (unique) key containing it. Single-column alternate (unique) key Select the table with the column you want to make a unique. Then, click the Alternate (unique) key tab in the Table properties panel on the right: Click Add key:
