MongoDB is one of the most popular NoSQL databases.
It is a nice and refreshing alternative to traditional relational databases (SQL databases).
Each represented entity is stored as a single document instead of being split into multiple tables.
Whether it will be better / simpler to use MongoDB compared to MySQL or a similar database server depends on the specific data.
Overall it is simple to start working with MongoDB and it is definitely a good tool to add to the toolbox.
At this point it is recommended to go over MongoDB manual: https://docs.mongodb.com/manual/introduction/
To start with MongoDB you need to:
1. Download and install: https://www.mongodb.com/download-center?jmp=docs
2. Create the default data folder (can be changed): c:\data\db
3. Run mongod from the command line.
In most cases you will use a three tier configuration where the clients access a B4J server and the B4J server communicates with the local MongoDB server.
I will post more examples next week. An example based on Alexa sites ranking data is available here:
www.b4x.com/b4j/files/MongoDBAlexaExample.zip
The data is loaded from a CSV file and then analyzed with different kinds of queries.
The library is attached.
It depends on an additional jar: https://repo1.maven.org/maven2/org/mongodb/mongo-java-driver/3.12.11/mongo-java-driver-3.12.11.jar
Copy the library and the jars to the additional libraries folder.
