In the last MongoDB example, How documents are represented in MongoDB Java Driver?, we’ve seen how MongoDB JSON documents are represented in MongoDB Java driver. Using this knowledge it is time for us to learn how to insert documents into MongoDB collections. We will create a code snippet that will insert documents into the teachers […]
MongoDB’s documents are stored inside a collections as a JSON (JavaScript Object Notation) document. It’s a string of key-value pairs data. JSON is a lightweight data-interchange format. It is easy for humans to read and write. It is easy for machines to parse and generate. When we are working in the MongoDB shell we can […]
In the previous post you have seen how we installed the MongoDB database server and try to use the MongoDB shell to manipulate collections in the database. You also have been introduced how to obtain and setup the MongoDB Java Driver that we can use to manipulate the MongoDB database from a Java program. Starting […]
In the past post Installing and Running MongoDB in Windows 7, you’ve seen how to install and running MongoDB database server. Now we are going to learn how to use the MongoDB Java Driver to access collections from the MongoDB database. To demonstrate this I am going to use Maven and IntelliJ IDEA. You can […]
What is MongoDB In this post you will see how to install and running MongoDB database server on Windows 7. What is MongoDB? MongoDB is a NoSQL database. MongoDB is a non-relational JSON document store, a document oriented database. Non-relational means that it does not support the relational algebra that most often expressed in SQL […]
Using Spring Expression Language (SpEL) we can filter a collection based on some criteria. We can also create a projection of a collection by collecting only a particular property from the collection objects. Now you know that you have two good features of SpEL that are really powerful to use when working with collection objects […]
