MATLAB® Interface for MongoDB

This is a MATLAB® interface that implements basic functionallity for MongoDB using the mongo-java-driver (https://github.com/mongodb/mongo-java-driver).

This library requires:

• MATLAB release R2017b or later
• Database Toolbox (for MongoDB API)

The original MongoDB API provided by MathWorks is implemented in the Microsoft® Azure Cosmos DB™

Getting started

To install the MongoDB API be sure the mongo-java-driver is added to MATLAB® Java class path variables.

javaaddpath('mongo-java-driver-3.12.0.jar','-end');

javaclasspath('-dynamic')

  DYNAMIC JAVA PATH

MongoDriver/mongo-java-driver-3.12.0.jar 

You should now be able to use the mongo command to open a connection. In addition to the MathWorks version the aggregation pipeline command was implemented to allow complex queries. Since the implementation is not tested, there is no guarantee for correct functionality.

MongoDB API

The following sample code connects to a database and inserts some sample data.

%% Create connection to Cosmos DB Mongo API
% Use valid values for localhost, testdb, myusername & mypassword
conn = mongo("localhost",27017,"testdb","UserName","<myusername>","Password","<mypassword>");

% Create a collection
myCollectionName = 'product';
conn.createCollection(myCollectionName);

% Check if there are anything in the collection already, there should not be
dataCount = count(conn, myCollectionName);

% Create some sample data
[insertcount, documents] = insert(mongodbconn,myCollectionName,'{"key1":"value1","key2":"value2"}')
[insertcount, documents] = insert(mongodbconn,myCollectionName,'{"key1":"value1","key2":"value3"}')

% Run some aggregation pipeline
result = aggregate(mongodbconn,myCollectionName,'[{"$group": {"_id": "$key1", "count": {"$sum": 1}}}]')

% Close the connection when finished
conn.close();
