What is database?

A database is a collection of information or data organized in such a way that it can be easily accessed, managed, and retrieved .

Therefore, its environment involves as main elements the hardware, software, procedure, the data itself and the users.

  • hardware includes physical parts and devices;
  • the software is its operating system and management system;
  • procedures involve a set of rules that govern the design and use of the database;
  • data is a collection of information
  • and users can be administrators or end users who use the database to access certain types of data.

The method of organization can vary based on purpose, type of data, or other factors, but at their core, they all consolidate data into a single digital location.

But a market trend that has been happening over time is database migration to the cloud , an important action for all companies.

What are the main database management systems?

There are many options when it comes to the type of database a company might want to implement. Each has its own benefits that help it perform a specific role. Some can even be used via AWS .

To help you get to know the main ones, let's introduce the 5 management systems .

1. Oracle Database

Oracle Database – or Oracle DB – is a relational database management system from Oracle. Originally developed in 1977, this is one of the most trusted and widely used relational database engines in the world. Since it is cross-platform, it can run on many different operating systems.

This option has several features that have popularized its use over time, such as partitioning, memory caching and Clustering, which allows services to operate without interruption if one or more servers in a cluster fail.

It is noteworthy that companies using Oracle Database will have to change their licensing to the new version, Database 19c, to continue to be supported by Oracle.

2. SQL Server

SQL Server is Microsoft's database management system. It works on the relational model (uses SQL, Structured Query Language), and supports a wide variety of transaction processing, business intelligence, and analytics applications in corporate IT environments.

Microsoft SQL Server is one of the three leading technologies in the market, and includes an engine that processes commands and queries along with another storage engine that manages the database's own files, tables, pages, indexes, data buffers and transactions.

3. MySQL

MySQL database manager, which is why it is quite popular. It works on a client-server model: the computers that install and run the software are called clients, and whenever they need to access data, they connect to the server.

Being an open source manager means you are free to use and modify it. Anyone can install the software and also learn and customize the source code to best suit their needs. The commercially licensed version is available if you need more flexible ownership and advanced support.

4. PostgreSQL

PostgreSQL is another open source database system, and is recognized in the market for being the most advanced among these types (as is the case with MySQL) .

An important feature of PostgreSQL is that it requires minimal efforts to maintain because of its stability. Therefore, if you develop applications in PostgreSQL, the total cost is low compared to other database management systems.

5. FirebirdDB

Firebird source relational database that offers many standard SQL language features that run on Linux, Windows and a variety of Unix platforms. This system offers high performance and one of the best language support on the market.

It even provides many features available to commercial databases, including stored procedures, replication, and backups available while it's running.
