Why Should You Learn MongoDB?

In this world of technology, data is very important and plays a crucial role in the industry. Almost every company in the IT industry is heavily dependent on data. However, these companies do not make use of data as it is, the data has to be processes and arranged in a particular manner before it can be used for a specific purpose. The raw and unprocessed data, isn't very useful.

They say now that ‘data is the new oil’ and rightly so because nowadays almost all businesses irrespective of their size or reach, use data to execute their daily operations. Their main aim is to drive their daily business by attracting a huge variety of customers. The task of structuring data has an entire industry dedicated to it. The huge amount of data is managed by various experts in this field. The data industry or database administrators have become hugely popular because there are growing number of businesses realising the power of data. If you are looking for a career in technology, handling and working with data using various tools, technologies and languages like MongoDB (the one we are going to talk about today) can be very lucrative career option.

In the database industry, most people are switching to the MongoDB database. Although there are many people who still prefer using a traditional relational database, but today we are going to discuss what is MongoDB and why you should choose. MongoDB is basically a document-oriented database program and is classified as a NoSQL database program. One important thing to consider is that MongoDB makes use of JSON-like documents with optional schemas. However, just like anything, MongoDB also has its own set of benefits and limitations. In this blog, we are going to understand this database in more detail and explore the reasons to learn MongoDB. Let’s get started with our blog where we try to answer ‘Why Should You Learn MongoDB?

Exploring MongoDB

There are a lot of reasons why you should choose MongoDB over others. The database boasts a worldwide popularity as more and more beginners are turning to this database and hence more applications are made which uses MongoDB. In this segment, we explore MongoDB and understand some of the reasons why MongoDB is popular.

One major benefit of MongoDb is Aggregation Framework which can be used it in a very efficient manner by MongoDB. One aggregation operation is MapReduce. It can also be used for batch processing. It is a process, in which large datasets is used and results are generated with the help of parallel and distributed algorithms on clusters. Map () and Reduce () are two sets of operations consisted in it. The Map function performs operations like filtering the data and sorting the dataset. The Reduce function, on the other hand, performs the operation of summarizing the data after the map () operation is applied.

Another feature of MongoDB is that it uses a BSON format. The BSON format is Binary JSON- like storage format. It is a serialization of JSON like documents which is binary encoded. It is used in MongoDB to store documents in collections. In this format, we can also add data types like date and binary that JSON doesn’t support. BSON format also enables to internally index and map the properties of a document. it also increases the read and write throughput of MongoDB as it is designed to be more efficient in both size and speed.

Scaling is a major problem with any web or mobile application. MongoDB has a solution for this as well that goes by the name of sharding. It is a feature or a method in which, data is distributed across multiple machines. Horizontal scalability is present with the feature of sharding. The process is complicated and is executes with the help of various shards in which each shard holds a part of data and functions as a separate database. A single database is formed by combining all the shards together. Sharding can also help us do horizontal scaling which is not possible even with relational database.

MongoDB also supports a wide range of queries, regular expressions and many more types of searches. These queries also include user-defined Javascript functions. However, MongoDB also supports ad hoc queries by using a unique query language.

Another attribute of MongoDB is that it is written in C++ and is a schema-less database. Hence, it is more flexible compared to the conventional databases and thus data in MongoDB does not require much to set up for itself.

MongoDB has a fixed size of collections as it supports capped collection. MongoDB maintains the order of insertion and once the limit is reached it starts functioning like a circular queue.

MongoDB also makes use of Indexing in order to improve the performance of search queries and hence the database engine is able to efficiently resolve queries.

MongoDB also supports Replication by distributing data across different machines. The replica set has one primary node but more than one secondary nodes. There is a concept of master-slave sets where the master set performs read and write operation but the slave can only copy data from a master as a backup and can only perform a read operation.

One powerful feature of MongoDB is the MongoDB Management Service. This feature can track our databases or machines along with backing up the data if required. MongoDB also tracks hardware metrics for managing the deployment along with providing custom alerts which helps us to discover issues before hand.

These were some of the major features of MongoDB. It is these features that helps the database stand out amongst so many others conventional and even new databases. These features help developers and programmers to work efficiently with data.

Now that we have a strong knowledge of MongoDb and its prominent features, it time to move on to our next segment where we talk about some of the benefits of using MongoDB database. These benefits will help you clearly answer the question, why learn database?

Benefits of Using MongoDB

The major benefit of MongoDB is load balancing. It is particularly useful when you have a large set of data. This data can be processed and then the traffic can be distributed amongst different machines with the help of load balancing. Load balancing is useful because it helps the user to continue their work even if one of the nodes or machines has stopped working due to some reason because the other nodes will keep working the processing will not stop.

Another major feature of MongoDB is flexibility as it does not require data structures. The flexibility of MongoDB makes it easier for everyone to use it. Also, the database is fast and it is easy to process data in it. MongoDB is efficient in handling a large amount of unstructured data within seconds and that is why it is the favourite amongst so many upcoming developers and computer science engineers.

Drawbacks of MongoDB

We have talked a lot about MongoDB, its features, benefits and why you should use it. However, there are some limitations of using MongoDB also. In this segment, we talk about the drawbacks, disadvantages or limitations of MongoDB.

One major disadvantage of MongoDB is the usage of memory. The database stores the key name along with every document and hence consumes a large amount of memory in the process.

Another disadvantage is that there are No Joins that are heavily and easily in other relational databases. However, it is not possible to apply joins in MongoDB and instead developers have to write many complex queries to perform operations of join. The absence of joins makes it very difficult to work with duplicate data.

Lastly, MongoDB is still under development as it had emerged only in 2009 and hence it is not yet fully documented or even tested. This is a major reason why MongoDB lacks the support from veterans and experts in the field.

This blog was an answer to the question why you should learn MongoDB. We hope the blog helped you can get an idea of the database and answered your question regarding it. We discussed its advantages and disadvantages which would hopefully help you choose the right database for you. However, if you have any doubt, please feel free to contact us as we would love to help you and build an enthusiastic community of technocrats.

Apart from playing with data and handling data, if you want to learn to develop web applications and websites, we encourage you to go ahead.
