Is MongoDB a Key to Getting a Job in NoSQL World?

Many corporations are still sticking to the traditional database management system. One of the reasons for that is the belief and difficulty in shifting. With that said, NoSQL is gaining momentum in recent years.According to the recently released report, NoSQL is expected to touch $4.2 billion by 2020, and,i.e., CAGR of 35% (2014-2020). We can expect NoSQL database usage to grow at a steady rate for times to come. Why? Here is an eye-opening graph.

It is much more convenient to handle unstructured data with NoSQL. The most preferredNoSQL database is MongoDB. There is a steady increase in the demand for NoSQL professionals.

An average MongoDB employee charges well over $95k annually (Source). If you want to getinto the field of NoSQL, you should enroll for online MongoDB certification training course.Proper training will walk you through all the theoretical and practical knowledge that you need toperform efficiently for your employers.If you want to get into the NoSQL industry, you must be able to separate facts from myths.

7 NoSQL Myths that Could Push You Back :

After you go through the myths about NoSQL that I am about to mention, you will be surprisedto see what people think about NoSQL. You may also have heard about some of the myths thatI’m about to reveal.

Here are the seven common myths about NoSQL:

1. NoSQL is all about one type of database

The truth is that NoSQL consists of common types of the database with common architectural approaches. It does not mean that NoSQL is only about one type of database. It is not for managing related rows and column table. The tables spread across many servers, and they do not have a hard time addressing data structure changes.Here are the different types of database that you will find under NoSQL:

● Key-Value: To offer quick and straightforward storage of simple data via a key.

● Column: To make users able to compute via large tables (not relational tables).

● Document: To make NoSQL able to process XML and JSON hierarchical formats.

● Triple/Graphs: To offer flexibility to document for a relationship.

2. ACID Principle is an alien term in NoSQL

ACID (Atomicity, Consistency, Isolation, Durability) compliance is a synonym to data safety.Many people believe that NoSQL does not follow the ACID principle. However, they are wrong. Aerospike, OrientDB, and so on are ACID compliant. They are either read-commit or fully sizable ACID compliant.Other NoSQL database technologies can use sensible setting to provide ACID-like compliance.MongoDB, Riak, and Microsoft Documented are some examples of those NoSQL databases.

3. NoSQL Database are not for enterprise applications

Here is one more myth that keeps people away from using NoSQL for enterprise applications.With that said, we can find many organizations that are using a NoSQL database for many critical projects:

● There are defense agencies that use NoSQL database.

● Many media companies save their digital assets in the NoSQL database.

● The media companies distribute searchable metadata catalogs with the help of theNoSQL database.

● There are banks that use NoSQL for managing primary trade information and also forimportant back-office purposes, such as risk-assessment systems.

● Even governments use NoSQL for their healthcare systems’ primary backends.

4.Only Web 2.0 make use of NoSQL

Here is one more big myth that is around NoSQL space. It is true that the web 2.0 and newmobile application stack contributed to the popularity of NoSQL. However, it is not limited tothese spaces. The startups use NoSQL, as it is easy to get started and one can use it for no cost under for free agreement.
The social media applications use NoSQL for extracting web published data and bundling it forfinding new insights. Many other applications besides web 2.0 use NoSQL where they need todeal with a substantial volume of unstructured data.

5. NoSQL=Open-source technologies

There is a massive volume of open-source NoSQL database technologies today. There are a lotof companies that are allowing users to use a NoSQL database under the open-sourceagreement after observing the success of RedHat.However, the companies that allow users to use their technology for free do not follow the openstandards. These companies create most of the codes. The users can only handle limitedfeatures under an open-source license. In no way, we can call it opensource technologies.Most of the people are not aware of many commercial companies that are revolving aroundNoSQL space after an exponential growth of NoSQL. Some of the thriving commercialcompanies that are offering NoSQL database technologies as a service are AeroSpike,Microsoft, MarkLogic, and Franz.We ought to observe many other commercial companies if it keeps on growing at a steady rate.

6. NoSQL is a fad that will go away shortly

I have seen people, claiming that NoSQL will fade away shortly. They perceive NoSQL asanother fad technology. However, that is further from the truth. If it were a fad technology, therewould have been no attention towards NoSQL from huge tech corporations.The huge corporations, such as IBM, Oracle, and Microsoft have their version of the NoSQLdatabase on the market. These companies are keeping a close eye on NoSQL growth and willbe focusing a lot on it once it meets their requirements.MarkLogic is an established company that has been around for years. It proves that NoSQL isnot only an exciting technology.Some people also believe that advanced RDBMS technology will kill NoSQL. However, that isalso not an accurate prediction. There has been a combination of RDBMS and NoSQL, knownas NewSQL, for overcoming RDBMS criticisms. However, it also revolves around RDBMS datastructures.There is still a considerable value for NoSQL database technology, as it is the only type oftechnology that addresses specific data problems and to handle different data structures.

7. NoSQL Developers have no clue about Relational Database

There is a rumor in a database community that NoSQL developers have no idea about thefundamentals of RDBMS. However, that is only a myth. NoSQL took birth after carefully goingthrough the problems that RDBMS could not address.In general, you can expect NoSQL developers to understand the fundamentals of RDBMS. Theonly thing is that NoSQL addresses problems that RDBMS cannot solve. NoSQL will not replaceRDBMS. RDBMS will be around and will have its importance. NoSQL will have its place forsolving different data problems and handling specific data structures.

Over to You

At times, we could be motivated to do something, but a misconception about that thing could hinder us from taking actions. The seven NoSQL myths that I’ve mentioned in the above section of this article have deceived many people into believing it.Now that you know about the seven common myths about NoSQL, you see the truth and can spread awareness. It will also enable you to take actions, and these lies will no longer affect you. There are many myths in the world today. One must research before believing any pieces of information.Have I missed out on any myths? If yes, do let us know by commenting below.
