Overview of the Certification
MongoDB is an open-source, NoSQL database that provides support for JSON-styled, document-oriented storage systems. It supports a flexible data model that enables you to store data of any structure and provides a rich set of features, including full index support, sharding, and replication.
MongoDB claims to be one of the biggest big data vendors with 400 employees, 2000 customers across the globe, close to 850 technology service partners that are increasing by 70% year-over-year. One-third of Fortune 100 companies are employing a MongoDB NoSQL database for mission-critical big data applications.
MongoDB offers certifications and training through MongoDB University. The program currently embraces two tracks, which the company calls roles:
- Database Administrators (DBAs) are fluent in managing MongoDB, including its run-time configuration, processes, sharding, backup and recovery, monitoring and performance tuning.
- Database Developers are fluent in one or more programming languages, each with its own associated MongoDB driver. They also understand the minutiae of performing MongoDB CRUD (Create, Read, Update and Delete) operations, indexing, aggregation, replication and basic database scaling.
