In basic terms, what we understand from a database is an assortment of data that is organized to be easily accessed, managed and updated to be accessible in a number of ways. To manage this data, we require Data Base Management System (DBMS) which helps in interacting with the end users, applications and the databases itself in order to capture and analyze the assorted data.
In other words, a DBMS is a collection of programs for managing data and support different types of users to create, manage, retrieve, update and store information.
The database management is highly competitive and complex as there is no single correct answer for every database problem. Since database management is an essential part of any software/website development, we own expertise in managing the databases in an efficient and effective manner. The databases can be categorized into various types:
Hierarchical database systems
Network database systems
Relational database management system
Object-oriented database systems
NoSQL or non-relational database systems
The most commonly used databases are the relational DBMS and the NoSQL DBMS. To understand what kind of data they manage, let us provide you with a little more detail.
Relational Database Management System
RDBMS is an information management system which is oriented on a data table where all the entities are stored in a tabular form. These databases are used where management of data is very large or huge information needs to be stored. Maintaining records with Relational DBMS offers you the following features:
A number of users can access the information together managed by a single user.
Indexes are required to retrieve the information.
Data is always saved in rows and columns.
Virtual tables are available for storing the data.
Examples of relational DBMS are Oracle, MySQL, MariaDB, MSSQL etc.
No SQL/Non-relational DBMS
The NoSQL database came as a solution over relational databases and allowed the users to store massive amounts of structured, semi-structured and unstructured data in real time. It is a highly scalable and flexible database management system. The NoSQL databases provide the following features:
NoSQL is agile as it does not create schemas and defines the data models.
Deployed over multiple cheap servers.
Suitable and equipped with big data operations, cloud, mobile and web technologies.
Instead of tables, it uses objects and collections.
Examples of non-relational DBMS are Mongo DB, H Base, Amazon Simple DB, Cassandra etc. Today most of the world famous firms like Google, Facebook, and Amazon are using this kind of database.
Our teams of experts work both on RDBMS as well as NoSQL databases in the enterprise level applications which we develop at Talentelgia. In fact, in some of our enterprise level solutions, we have also used a mix of RDBMS and NoSQL databases for different purposes to ensure optimum performance of the application.
