According to the 2023 Stack Overflow Developer Survey, PostgreSQL has achieved a significant milestone by overtaking MySQL as the most admired and desired database system among developers. This shift reflects a growing appreciation for PostgreSQL's robust feature set, reliability, and extensibility in the developer community.
This changing landscape has sparked innovation in the database-as-a-service space, particularly evident in the competition between two cutting-edge platforms: PlanetScale, built on MySQL, and Neon, powered by PostgreSQL. Both services are reimagining how developers interact with databases in the cloud era. These developments should be of interest to Navicat users, as both are fully supported by Navicat's comprehensive database development and management tools.
This blog will provide a comparison of the two services and offer some tips for choosing between them.
Range Types
It's no secret that PostgreSQL is one of the most flexible databases on the market. In fact, PostgreSQL's extensibility and rich feature set recently propelled PostgreSQL ahead of MySQL as the most admired and desired database system among developers. In this series on creating custom data types in PostgreSQL using Navicat Premium 17 we've explored a few options so far, including custom Domains, as well as Composite and Enumerated types. The topic of this week's blog will be Range types, which are particularly useful when you need to work with continuous intervals or ranges of values.
Enumerated Types
In this series on creating custom data types in PostgreSQL using Navicat Premium 17 we've explored a couple of options so far. In part 1, we learned how to create a custom Domain for the free DVD Rental database. Last week, we created a Composite Type to return complex data from a user-defined function. Today's blog will cover Enumerated Types, which limit values a set of predefined options.
Composite Types
Welcome to the second installment of this series on creating custom data types in PostgreSQL using Navicat Premium 17. In part 1, we learned how to create a custom Domain for the free DVD Rental database. A Domain is a user-defined data type with constraints such as NOT NULL and CHECK. In today's blog, we'll create a Composite Type to return complex data from a user-defined function.
Domains
Storing data in proper formats ensures data integrity, prevents errors, optimizes performance, and maintains consistency across systems by enforcing validation rules and enabling efficient data management. For these reasons, top tier relational databases like PostgreSQL offer a variety of data types. In addition, PostgreSQL enables custom data type creation via the "CREATE DOMAIN" and "CREATE TYPE" statements, allowing developers to extend data types for enhanced application-specific data validation, integrity, and consistency. In today's blog, we'll learn how to create a custom Domain for the free DVD Rental database using Navicat Premium 17. Part 2 will cover Types.
