It is hard to imagine that, for more than 50 years, companies did not know about Database Management System (DBMS) and used to store relevant customer information on schedules and files. This was the real scenario. Until, in the early 1970s, they began to emerge the first DBMSs, ensuring more consistency, safety, and accessibility of data.
It is true that small businesses still use Excel or Access to store data, but face it, no longer makes sense to many DBMSs available.
Before we go into details about the available DBMSs, it is important to understand the difference that exists between the two languages, SQL and NoSQL. The first data structure in table form. It is, therefore, a relational model. In turn, the NoSQL language uses a non-relational model, in which data is distributed horizontally.
After this brief introduction, it’s time to evaluate four types of DBMS:
MySQL is a relational database management system (open source), i.e., it runs as a server and allows multiple users to manage and create numerous databases. WordPress, for example, requires MySQL to store and retrieve all your data, including content posts, user profiles, and so on. Most hosting providers already have MySQL installed on their web servers, since it is widely used in many open source web applications.
Therefore, it makes sense to use MySQL for web projects, such as e-commerce sites.
Created in 1988, the SQL Server is Microsoft’s database management system and, therefore, it only runs on Windows operating systems. This program is widely used on sites that need records and stores systems, which are launched products, prices, brands, and other information. It is recommended also to create a database in structured systems outside the web.
MongoDB, established in 2007, is a more complex database management system, which uses MongoDB language. Being very robust, the learning curve is very large.
As for projects, MongoDB is more compatible with the sites that get a lot of hits and you need quick answers since it is not attached to the modeling and offers scalability. MTV, EasyTaxi, Foursquare, and Bit.ly are some of the main users of this database.
PostgreSQL is an extremely robust database system capable of supporting a large volume of data. In addition, it has low maintenance cost and high stability. To get an idea, Apple, NASA, Skype, Metro-SP, among others, use PostgreSQL as DBMS.
With its features, all presented DBMSs help to organize and manipulate information of the companies. Now you can evaluate your projects and technical expertise to decide what DBMS can be implemented.
