Databases are a great way to add data persistence to your project or application. You can write data in one session and it’ll be there the next time you want to look. A well-designed database can be efficient at looking up data in large datasets, and you won’t have to worry about how it looks, just what you want it to find. It’s fairly simple to set up a database for basic CRUD (create, record, update, delete) applications, which is a common pattern, and it is useful in many projects.
Why PostgreSQL, commonly known as Postgres? It’s considered to be the best open source database in terms of features and performance. It’ll feel familiar if you’ve used MySQL, but when you need more advanced usage, you’ll find the optimization in Postgres is far superior. It’s easy to install, easy to use, easy to secure, and runs well on the Raspberry Pi 3.

Stop breadboarding and soldering – start making immediately! Adafruit’s Circuit Playground is jam-packed with LEDs, sensors, buttons, alligator clip pads and more. Build projects with Circuit Playground in a few minutes with the drag-and-drop MakeCode programming site, learn computer science using the CS Discoveries class on code.org, jump into CircuitPython to learn Python and hardware together, TinyGO, or even use the Arduino IDE. Circuit Playground Express is the newest and best Circuit Playground board, with support for CircuitPython, MakeCode, and Arduino. It has a powerful processor, 10 NeoPixels, mini speaker, InfraRed receive and transmit, two buttons, a switch, 14 alligator clip pads, and lots of sensors: capacitive touch, IR proximity, temperature, light, motion and sound. A whole wide world of electronics and coding is waiting for you, and it fits in the palm of your hand.
