Difference between Oracle and PouchDB

1. Oracle :
Oracle is a relational management system. It is developed by Oracle Corporation in 1980. It is the first database designed for grid computing that provides the most flexible and cost-effective way to manage information and application. It runs a major platform like WINDOWS, UNIX, LINUX and MACOS. It will relational database in which data accessed by the user through the application or query language called SQL.

PouchDB is an open-source, NoSQL, in-line database. It is designed after CouchDB, which is a NoSQL database that powers npm. It is written in JavaScript language. There is no need to perform queries over the network as PouchDB resides inside the browser and thus it makes it extremely faster. It stores data locally using IndexedDB and WebSQL in the browser.
