Part 5 - Building Robust Enterprise Systems: An Introduction to Essential Technologies (Database Technologies)
Written by : Sanjay Purohit
As we continue our series on the essential technologies used to build enterprise-level systems, we now turn our attention to database technologies. The database is a critical component of enterprise systems because it's where all of the data is stored and managed.
What is Database Technologies ?
A database is an organized collection of data. It is designed so that it is easy to store, access, and manage data. Databases can hold a vast amount of data and allow multiple users to interact with that data at the same time. In addition to simply storing data, databases also maintain the relationships between different types of data, which is critical for understanding the context and gaining insights.
Database technologies refer to the tools, systems, and software used to create, manage, and interact with databases. They are at the heart of a broad range of enterprise applications and play a crucial role in software development. Different types of database technologies are used depending on the specific requirements of the system, including relational databases, NoSQL databases, in-memory databases, and more.
Here are some popular database technologies that you'll commonly encounter in enterprise systems:
-
MySQLThis open-source relational database is widely used due to its reliability and robustness. It uses SQL (Structured Query Language) for managing and retrieving data.
-
PostgreSQL
This is a powerful, open-source object-relational database system that is known for its proven architecture, reliability, data integrity, and robust feature set.
-
Oracle Database
Oracle DB is a multi-model database management system provided by Oracle Corporation. It is widely used in enterprise applications.
-
Microsoft SQL Server
This is a relational database management system developed by Microsoft. It is widely used in the enterprise for its performance, scalability, and security features.
-
MongoDB
MongoDB is a popular NoSQL database that provides high performance, high availability, and easy scalability.
-
Cassandra
Developed by Apache, this is a free and open-source distributed NoSQL database system designed to handle large amounts of data across many commodity servers, providing high availability with no single point of failure.
-
Redis
An open-source in-memory data structure store, used as a database, cache, and message broker.
-
MariaDB
A community-developed, commercially supported fork of the MySQL relational database management system, intended to remain free and open-source software under the GNU General Public License.
-
DB2
Developed by IBM, this is a database product family that provides flexible and powerful database technology for managing core business data.
-
SQLite
A C-library that provides a lightweight disk-based database. It allows accessing the database using a nonstandard variant of the SQL query language.
-
HBase
An open-source, non-relational, distributed database modeled after Google's Bigtable and written in Java.
-
CouchDB
An open-source database software that focuses on ease of use and embracing the web.
