![]() To add a column to the table, simply click on the + Add Column button in the Columns section. The first thing we are going to do is to provide a name and description for the table: Adding Columns ![]() It allows us to start defining all the details of the new table. The Table properties panel will appear on the right side of the Redshift ER diagram. To add a table to the model, we click on the third icon of the diagram taskbar (marked in red) and then click on any empty space in the diagram: Once we’ve made these selections, we press the Start Modeling button:Īnd now we are ready to start modeling! Adding Tables Then we need to provide a name for the data model and select the desired database engine (here, Redshift). In this case, we need to pick the Physical Data Model, as shown below: We need to select the type of document we want to create. Creating a Redshift Physical Data Model Using VertabeloĪfter logging in into the Vertabelo data modeler (you can request a free trial account if you are not already a user), we’ll create a new Redshift ER diagram by clicking on the Create new document icon on the left section of the taskbar: See the article Converting an Analytics System from Postgres to Redshift to learn how to move your PostgreSQL to Amazon Redshift.Īnd before you start designing your data model, take a look at the article Best Database Modeling Tools for Redshift to review the best tools available for data modeling with Redshift. Since Redshift is based on PostgreSQL 8.0, migrating from PostgreSQL databases to Redshift is quite simple. Redshift is fully managed, meaning that all operations (like backups, patching, etc.) are completely handled by Amazon without requiring user intervention. As with many other data warehouse implementations, data is stored in columnar-based structures rather than row-based ones MPP (Massive Parallel Processing) technologies allow Redshift to process huge amounts of data in a very short time while still using the well-known SQL language. What Is Amazon Redshift?Īmazon Redshift is a Cloud-based, data warehouse oriented implementation of PostgreSQL database engine designed and offered by Amazon. ![]() (Vertabelo also supports other database management systems, but in this article we’ll focus on the Amazon Redshift DBMS). ![]() It allows you to design and implement a database model in a simple way. This article will show you how to use Vertabelo as a database modeling tool for Redshift. See how Vertabelo can help you design a database diagram for Redshift. ![]()
