Top 7 Useful Online Database Tools

Let’s discuss some useful tools for designing and developing your database hassle free while saving you money and time.

In the modern software world, database systems play an important role. Most businesses depend on various database systems. Database architects and software engineers design and develop various types of database systems to manage the business. Online database tools have become very well known among database specialists and software engineers for their advantages.

The database design process is not just about drawing an ERD and converting it into a physical database; there is a wider process behind the database design process. That is why we need to use the right tools such as online data modelers, SQL editors, etc., for each phase of this process.

Design Your Concept: In this phase, you gather business and non-functional requirements through discussions with business teams, then you start to model your concept. You will have to go back and forth with the business on your conceptual model. For that reason, you need flexible tools to model your concept. Online data modeling tools are especially suited for the collaborative work with the business team required during this phase. I would like to suggest the following tools for your conceptual model:

Logical and Physical Data Modeling: Next, you will draw your logical and physical data models and present them to the software engineers. This too is a back-and-forth process between the data modeler and the software engineers who will influence each other’s work. To make this process smoother, I recommend a couple of tools that support easy collaboration, change management, version control, automation, etc.

Create Your Physical Database: With modern online database tools, you have many features for creating your physical database from the physical data model without creating it from scratch. For this phase of continuous changes, I recommend the following tools which have many features to help make your project successful.

Create and Manage Your Physical Database: I recommend the following online tool for creating and managing your physical database.

Test Your SQL Queries: During your database designing process, having SQL tools, SQL editors, and online tools for testing SQL queries would be very useful, since we don’t always have the specific database engine at our disposal. There are many online SQL tools and SQL editors available in the market for testing our queries. We will discuss the features of a few of them.

Online Tools for Designing Your Concept

Vertabelo Online Data Modeler

The Vertabelo Data Modeler is one of the best available in the market. It is an online tool which makes many tasks easier than offline tools and provides two modeling options: logical and physical. You can use the logical data model option for your conceptual data model with less information, as shown in the ER diagram below in Vertabelo. Note that there is no clear line between the definitions of conceptual and logical data models, so data modelers can use them as they see fit.

Vertabelo comes with all of the required notations including crow’s foot notations, not just to model your concept but also to model your logical and physical data models. Because it is an online tool, it makes it easy to model your concept while interacting frequently with the business team. You can share your data model with your business team with the sharing feature in Vertabelo. Simply provide the email addresses of your business team members or of any others with whom you want to share the model, and click the button to specify one of the three different access levels: owner, editor, or viewer. You can also share your data model by emailing the public link to your business team members who do not have a Vertabelo account. Read more on collaboration in Vertabelo.

Furthermore, it has a version control feature with Git, with which you can manage the different versions of your model. To learn more about this, read How to Version Control Your Database with Vertabelo and Git.
