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.

Remote Collaboration on Database Design Just Got Easier

As an SQL consultant, I often work with others to create new database models from scratch or modify existing schemas. Aside from the technical aspects, collaborations on database models can be tricky. Moving from environment to environment poses its own challenges: security restrictions sometimes prevent direct access to SQL instances, and technical resources from across the globe can be difficult to seamlessly integrate. Deterrents these may be, but they are not insurmountable.

Defining Identifying and Non-Identifying Relationships in Vertabelo

Various data modeling tools allow modelers to define relationships in a data-model as identifying or non-identifying. We can define a relationship as identifying or non-identifying in Vertabelo as well. This article will explain the way to do so. Introduction Before moving ahead with the article, I’d like to explain what identifying or non-identifying mean. Let’s take a real time example of a book storing system. In the system, a book belongs to an owner, and an owner can own multiple books.

How to Convert a Data Model Between Two Database Management Systems

Even though Vertabelo doesn’t provide a direct conversion of a data model from one database engine to another, this can be easily done in a few simple steps. The user’s question We’ve been developing a web application for a while. Initially, we wanted to use MySQL for our database but finally we decided to choose Postgres. Unfortunately, the entire data model was created for MySQL. How can we quickly migrate it to the new database type?

That’s why we provide our users with some useful tools on our website and in our GitHub repository.

How to Color ERD Diagrams in Vertabelo

If you’ve ever had to design a database model with hundreds of tables, views and references, you know very well how difficult is to make such huge diagram readable and comprehensible. One of the possible solutions is to use some colors to distinguish different groups of tables or subject areas. See how Vertabelo allows you to do this quick and easy. To illustrate how you can color your entity relationship diagram to increase its readability, we will use a sample uncolored database model for a simple online store:

How I Use the Vertabelo API With Gradle

What is Gradle? Gradle is an open source build automation system. It can automate the building, testing, publishing, deployment and more of software packages or other types of projects such as generated static websites, generated documentation or indeed anything else.

One of the exciting moments in a programmer’s life is to leave legacy code behind and have fun with some new, fresh and cool tools.

Data Dictionary Support: Generate Comments for Your Database

Most relational databases allow you to define comments for their tables, columns, views, and so on. These additional pieces of information are called database meta data or data dictionary. Meta data may be useful for developers or other database users. Meta data allow the development team to understand what various tables or columns are for without having to ask database designer what their intentions were. Generating meta data in SQL scripts is one of the most often requested Vertabelo features and it’s finally here.

Now You Can Print a Diagram

We hadn’t planned on adding a feature to print diagrams. Our original idea was that Vertabelo would supersede paper diagrams. Nevertheless, some of our users pointed out that they rely heavily on printouts (Export to PDF topic). So, I’d like to announce a new feature called “Export to PDF” also known as “Printing.” Note that exporting a database model to a PDF file is available for Premium and Team account plans only (see the comparison of the plans’ features in our Pricing).

Vertabelo XML version 2.1

Vertabelo internally stores your model in an XML format. You can download the XML file and use it to extract some information by using a script. Let’s take a look at the structure of this XML file. if (typeof VertabeloEmbededObject === 'undefined') {var VertabeloEmbededObject = "loading";var s=document.createElement("script");s.setAttribute("type","text/javascript");s.setAttribute("src", "https://my.vertabelo.com/js/public-model/v1/api.js");(document.getElementsByTagName("head")[0] || document.documentElement ).appendChild(s);} Here is the XSD file and an example of the XML file for the above sample database model created in Vertabelo.

How to filter tables in the Vertabelo reverse engineering tool

Sometimes you don't want the reverse engineering tool to extract all of the tables in your database. For example, the database may contain technical tables which are logically are not part of the model. This is when the -regexp option comes in handy. Use the -regexp option and the tool will extract all tables and views with names matching the regular expression. The tool prints the regular expression it uses so you can verify that your shell parsed the expression correctly.

How to import an existing database into Vertabelo: Reverse Engineering

The newest Vertabelo feature is Reverse Engineering: a way to import an existing database into Vertabelo.
