Document Database A record in MongoDB is a document, which is a data structure composed of field and value pairs. MongoDB documents are similar to JSON objects. The values of fields may include other documents, arrays, and arrays of documents. The advantages of using documents are: Documents...
BSON strings are UTF-8. In general, drivers for each programming language convert from the language’s string format to UTF-8 when serializing and deserializing BSON. This makes it possible to store most international characters in BSON strings with ease. In addition, MongoDB$regexqueries support...
After spending the time to design your data schema in an appropriate fashion for your application, one needs to be able to retrieve it. In MongoDB, there are two basic ways that data retrieval can be done: through queries with the find() command, and through analytics using the aggregation...
We use the@Documentannotation to mark our entity class as a MongoDB document, mapping it to theauthorscollection in the database.Additionally, we use the@Idannotation to specify our primary key. By default, the name of the entity attribute is mapped to the document field name.To map our a...
After this introduction to MongoDB Atlas, you’ll learn how to set up a cluster using the M0 free tier, whitelist a connection IP address, and create the MongoDB user which you’ll then use to connect to your cluster through Studio 3T. ...
BSON documents may have more than one field with the same name. MostMongoDB interfaces, however, represent MongoDB with a structure (e.g. a hash table) that does not support duplicate field names. If you need to manipulate documents that have more than one field with the same name, see...

MongoDB -- from humongous -- is an open source, non-relational, document-oriented database. The goal of the MongoDB project is to bridge the gap between key-value stores (which are fast and highly scalable) and traditional RDBMS systems (which provide ri
