PostGIS is open source extension onf PostgreSQL object-relational database system that allows GIS objects to be stored and allows querying for information and location services. The aim of this book is to help you master the functionalities offered by PostGIS- from data creation, analysis and output, to ETL and live edits. The book begins with an overview of the key concepts related to spatial database systems and how it applies to Spatial RMDS. You will learn to load different formats into your Postgres instance, investigate the spatial nature of your raster data, and finally export it using built-in functionalities or 3th party tools for backup or representational purposes. Through the course of this book, you will be presented with many examples on how to interact with the database using JavaScript and Node.js. Sample web-based applications interacting with backend PostGIS will also be presented throughout the book, so you can get comfortable with the modern ways of consuming and modifying your spatial data.
22. Introduction — Spatial Data Management with Earth Engine
A database management system (DBMS) allows users to store, insert, delete, and update information in a database. Spatial databases go a step further because they record data with geographic coordinates.

TigerFS
A filesystem backed by PostgreSQL, and a filesystem interface to PostgreSQL. TigerFS mounts a database as a directory. Every file is a real row. Writes are transactions. Multiple agents and humans can read and write concurrently with full ACID guarantees, locally or across machines. Any tool that works with files works out of the box.
Relational foundations for functorial data migration | Proceedings of the 15th Symposium on Database Programming Languages
In this paper we present a simple database definition language: that of categories and functors. A database schema is a small category and an instance is a set-valued functor on it. We show that morphisms of schemas induce three ''data migration ...
