Document

Mongodb: MongoDB is a free and open-source cross-platform document-oriented database program. Classified as a NoSQL database program, MongoDB uses JSON-like documents with schemas.

To run this project a MongoDB instance is required, so you can use either a local instalation or using Docker.

Check the code

This part has 2 configuration files and 8 classes

• src/main/resources/META-INF/beans.xml: CDI configuration file

• src/main/resources/diana-mongodb.properties: Database connection configuration file

• column/src/main/java/org/jnosql/demo/document/DocumentCollectionProducer.java: Connection handler

• column/src/main/java/org/jnosql/demo/document/Person: This class is a org.jnosql.artemis.Entity to model a Person

• column/src/main/java/org/jnosql/demo/document/Address: This class is a org.jnosql.artemis.Entity to model an Address

• column/src/main/java/org/jnosql/demo/document/Job: This class is a org.jnosql.artemis.Entity to model a Job

• column/src/main/java/org/jnosql/demo/document/PersonBuilder: builder to create a Person entity

• column/src/main/java/org/jnosql/demo/document/PersonRepository: Artemis Repository for Person entity

• column/src/main/java/org/jnosql/demo/document/App: This class will be used to make the exercises.

  • This class creates and persist into MongoDB one person with address and job and 2 telephone numbers and then queries it:

   Person person = Person.builder().
                   withPhones(Arrays.asList("234", "432"))
                   .withName("Name")
                   .withAddress(address)
                   .withJob(job)
                   .withId(id).build();

• column/src/main/java/org/jnosql/demo/document/App2: This class will be used to make the exercises.

  • This class creates and persist into MongoDB one person with 2 telephone numbers and then queries it:

   Person person = Person.builder().
                   withPhones(Arrays.asList("234", "432"))
                   .withName("Name")
                   .withId(id)
               .build(); 

Start the workshop

1. Run the MongoDB Docker instance

   docker run -d --name mongodb-instance -p 27017:27017 mongodb
   

2. Compile the project via Maven

   mvn compile
   

3. Run the project via Maven

   mvn exec:java -Dexec.mainClass="org.jnosql.demo.document.App"
   
   mvn exec:java -Dexec.mainClass="org.jnosql.demo.document.App2"
   

Time to practice

Now, It is time you explore the code: add new persons, more relationships, and create new queries. Also you can try to an create your own entities that can be used to respond some questions, next some ideas:

• Implement some searches against a MongoDB
• Search JUG members in a given city
• Search JUG members of legal drinking age
• Search JUGs in a region
