An Object-Relational Database (ORD) combines both entity-relationship modelling and object-oriented mapping techniques to enable the efficient organization of data from a limited set of data types. As a result, this database model is often referred to as an intermediate solution between object-oriented and relational databases. Using Object-Relational Database Management Systems (ORDBMS), organizations can implement inheritance, enable complex data types that enable useful data manipulation and extend existing data models.
PostgreSQL is one free, open-source ORDBMS that is popularly used to manage the primary back end databases of dynamic websites, web applications and geospatial databases. OpenEBS LocalPV devices offer the perfect solution to orchestrate Kubernetes storage for PostgreSQL databases, which often deal with heavy loads. OpenEBS includes a number of storage engines that can be chosen according to the storage available on physical devices and application needs. This post demonstrates how to deploy PostgreSQL Kubernetes operators using OpenEBS LocalPV devices.
