This document compares the NoSQL databases MongoDB and OrientDB. MongoDB was created in 2009 and uses a document data model, while OrientDB was created in 2010 and uses both document and graph data models, making it a hybrid database. The document discusses the key features and uses of each database, such as MongoDB being best for large amounts of non-relational data without transactions, while OrientDB supports transactions, relationships between data, and a SQL-like query language. Examples of data modeling in each database are also provided.
