Using a visual designer such as DbSchema will make your work even easier by enabling you to do everything visually, without having to write a single line of code.We have been using Visual Studio Database projects for a while now and they work great for deployments. Understanding the concepts listed above will help you to easily manage your PostgreSQL schemas. If a change appears in development and you want to implement it over the other two schemas, you can just compare and synchronize the two project files. For example, if you work in a team, it may be the case that there are multiple schemas (production, testing, development) each with its own project file. The same thing can be done between two different versions of the same project file. After reconnecting to the database, you can compare the project file with the database and choose what actions to keep or drop. While offline, you can do all the actions presented above and more, but without data. This means that the project file can be opened without database connectivity (offline). Work OfflineДbSchema stores a local image of the schema in a local project file. Each layout has one schema associated with it, so if you are on the schema_1 layout, the tables will be automatically created there. A layout can be compared to a drawing board on which you can add the tables and edit them. Using DbSchema, you wonвЂ™t need to use the show_path syntax because you can create the tables right in the layout. To add another schema from the database, choose Refresh From Database. The schema can be dropped by right-clicking on its name from the left menu. To create a new table in the schema right-click on the layout and choose Create Table. To create a new schema, just right-click on the schema folder on the left menu and select Create Schema. The selected schema or schemas will be reverse-engineered by DbSchema and showed in the layout. From the beginning, you can select on what schema to work. Connecting to the database will only take a few seconds. Using DbSchema you can execute all the queries above from an intuitive GUI with just a few clicks. There is a simpler way to do all the schema management tasks, without having to write any line of code. A new schema can be created by executing the next query: When you create a new database in Postgres, the default schema is public. The classic way of managing PostgreSQL schemasДЄll the queries below will be executed from inside the PostgreSQL shell. A common example is when each database user works on its own schema, without interfering with other users and avoiding conflicts. Besides this, schemas are often used to allow different users to work with the database without interfering with each other. Schemas are very useful to organize database objects into logical groups and avoid name collision. For example, we can have two tables both named table1 present in public and in postgres schemas. ItвЂ™s not allowed to create two tables with the same name in one schema, but you can do it in two different schemas. It is used to identify and differentiate certain objects in the database (tables, views, columns, etc.). The namespace can be associated with a family name. In Postgres, the schema is also referred to as a namespace. What is a PostgreSQL Schema?ДЇirst, to lay the groundwork for the article, letвЂ™s clear off some terminology. In this article, we are going to look at the traditional way of managing a Postgres schema and at a newer, more effective way to do it visually, without having to write any line of code. Getting to understand the basics of schema management is crucial for building and maintaining an effective PostgreSQL database.
