Top 5 Popular Databases in 2019: Advantages and Disadvantages
What comes to your mind, when you think of data storage – with no doubt, it would be a database. Storing information and related contents for everything, including product catalogs, and repositories of customer information are what constitutes the main functionalities of a database. With database management systems, understanding, accessing and using the stored data becomes easier.
Organizing the information and linking databases to one another, while also providing reports on changes and trends within the data stored in the database can be managed only by database management systems. But before we provide you with an understanding of what are the different kinds of databases and what features each offer, it is important to have a clear understanding of a database.
A brief overview
Database management systems are capable of performing similar basic tasks, including creating, altering and accessing the data/information stored in databases, these systems differ from one another in how these activities are performed. The features, support and even the functionalities supported by each of these systems might differ from one another. The first and foremost thing that you need to take into account is the user-friendliness offered by a DBMS and to what extent it can be scaled along with its integration capacity with those products with which it will come in contact.
Apart from these factors, it will also be great if you can have a clear picture of the cost of these management systems and the support that each of them can offer you with. As your organization expands, these database management engines also need to be enhanced and improved. Regardless of your business size, even if it is a start-up, which requires only limited functionalities owing to the small amount of data that it needs to manage, it is important to consider how the database can be altered to incorporate the changes that pop up over time. In some situations, even switching over to another database management system would be one of the best solutions.
We have listed out some of the best and popular databases with their features, which will help you decide which of them would fit exactly well into your business requirements.

Like MySQL, Mongo DB is another database that has both a free version and a paid version. The apps designed using Mongo DB rely upon or can use both structured and unstructured data. Mongo DB has a database engine, which is adaptable and flexible, and works by connecting database apps through Mongo DB database drivers. It is a hassle-free task to find a driver that fits exactly or can be integrated well with the programming language as it offers a complete set of sophisticated drivers. One of the latest versions of Mongo DB is Mongo DB 3.2. This comes with new and pluggable storage engines.
It is best to avoid using Mongo DB to manage relational data model though it can deal with these as it might lead to performance issues. But the database engine has been designed such that it can handle variable data, which is not relational and is capable of performing well in such situations where other databases might not perform better.
It provides you with the provision of improvising search functions. Also, the documents can be validated by using updates and inserts. If you shrink the size of indices, you would create a new partial index capability, which leads to enhanced performance.
