We all use several different websites on a daily basis, right? Mostly all of them use databases to collect and store the data. Have you ever asked yourself how do database servers work? Every budding programmer or computer geek might stumble upon this database server working model. Here is a startup guide for you to track the working mechanism of Database Servers.

The best part: It is a good visual treat, a visual representation well covered with Text. So without wasting any time, let’s begin.

What are Database Servers?

Let me start with the basic definition of a Database and Database Server.

Definition: A database is a collection of information that is organized so that it can easily be accessed, managed, and updated.

A database server is a computer program that provides database services to other computer programs or computers using a client-server model. The term may also refer to a computer dedicated to running such a program.

Also, you should know that there are many different types of database server software. Some are open source (ie. MySQL, MongoDB, PostgresSQL) and some are commercial software (ie. MSSQL, Oracle).

Now that we know what the Database Server term means, let’s explore the communication process of the client-server model.

The process is not that complicated. Imagine that some computer has a contently running program that can understand some special language (SQL or Structured Query Language), but only listens to someone specific (security measure) rather than everyone who tries to talk to it.

Now when someone who is allowed to talk to Database Server sends it a command, the command will be processed and necessary data selected or updated from/to database storage and result sent back to the requester.

Do you want to SQL the fun way: Try this!

Different types of database servers use different data storage techniques (also called engines) and usually can utilize multiple engines at the same time depending on your needs. In most cases, all data is physically stored as files on the same computer where the database server is running, or on any remote storage.

Top Enterprise Database Software & System

Database Software & system is a highly competitive market, as mare minutes of downtime can mean millions in losses for any enterprise. Enterprise database systems enable features like hot backups to scalability & high availability. This database ranges in prices, some are free of cost while others cost tens of thousands of dollars.

There is no single correct solution for each data problem. Each of these enterprise database solutions offers its own set of features and shortcomings.
