When I started working on mongoDB the challenge was to train my team on mongoDB and we had to create a workshop so that people could seamlessly transition to MongoDB. I am going to share few pointers and tools that you can use if you are working on mongoDB.
I assume you are familiar with some RDBMS.If you have worked with Oracle or any other RDBMS then it is not quite difficult to pick a NoSQL database like MongoDB. Oracle is an object-relational database system that comprises of table-column-row (TCR) structure. The data in oracle database is stored logically in tables. These tables are then logically grouped in table-spaces. Oracle database physically stores data in data files. Table-spaces contain segments. These segments are made of one or more extents. An extent is the collection of contiguous data blocks. Thus data blocks are basic units of data storage in Oracle.
In comparison to Oracle mongoDB is a NoSQL document-oriented database. It is basically a class and object (CO) structured database. mongoDB contains multiple databases. Each database comprises of collections. A collection is formed of one or more documents. These documents contain fields where data is stored in the form of key-value pair.
I have shared a quick reference table to relate Oracle/RDBMS and mongoDB. In the next post I will share some sample code to understand how data is accessed in mongoDB as compared to RDBMS and it is quite different from the plsql code you have been used to.
