MongoDB training
Audience
Developers, Automated
Testing Engineers, operations professionals and anybody interested in deep
knowledge of MongoDB.
Preface
MongoDB (from
"humongous") is a document-oriented NoSQL database with JSON-style
documents written in C++ and using JavaScript for internal purposes. Designed
for the data and scalability requirements of modern internet applications,
MongoDB features dynamic queries and secondary indexes, fast atomic updates and
complex aggregations and support for replication with automatic failover and
sharding for scaling horizontally. MongoDB is an open-source and very popular
among both developers and operations professionals given its agile and scalable
approach.
Necessary knowledge
Software
engineering. JavaScript core (ECMA-262 standard). Basic concept of databases.
Relational
database management system (RDBMS) and SQL will be advantage.
Training Description
The training
describes base concepts, features and syntax of MongoDB. It gives theoretical
and practical information about MongoDB, observe best practices and typical
issues and give you the way to develop horizontally scalable and highly available
web applications with automated failover, working with humongous set of data.
Training goals
The training
go over basic installation, «schema design», querying, inserting and updating data,
indexing and working with aggregation framework. It also covers working in
sharded and replicated environments and observe the latest MongoDB features
like Geospatial Indexes, Grid FS, Text search, Time To Live (TTL) and Caped
collections.
After
completing this course attendee will be able to do everything from «Training Agenda» as well as using
documentation for reference and further education.
