The world of technology is becoming increasingly complex and advanced, meaning that every student in the technology field has to do whatever it takes to stay relevant in this ever-changing field, and learning a database is one of the best ways to do that. Learning databases can open you up to a world of data-driven opportunities. However, the kind of database you learn depends on factors such as the requirements of your academic program, your career goals, and the job market among others. If you are wondering, “What database should I learn as a student?” I have compiled a list of the popular databases that you can choose from depending on the above factors.
Relational databases
These are the database management systems that use a structured approach when it comes to storing and managing data. These are the most widely used database management systems (DBMS) because of their efficiency.
MySQL
MySQL is one of the open-source relational databases that is commonly used for a wide range of applications. MySQL is popular because of its speed and efficiency when it comes to retrieving and manipulating data, meaning that it can handle a large volume of users and transactions. MySQL is also quite compatible with various programming languages, meaning that it is a relevant skill to have. If you are looking to become a software developer, data administrator, or data engineer, then MySQL is the perfect choice for a relational database to learn.
SQLite
SQLite is one of the most versatile relational databases that is known for its lightweight and self-contained nature. SQLite is quite lightweight since it is just a small library that can be embedded directly into an application. This means that SQLite does not need a standalone server, which adds to its simplicity. SQLite is also quite easy to not only transport but also manage since the entire database is self-contained in a single file. SQLite can be used in mobile and desktop applications. It is also excellent for prototyping and development, which makes it a great choice for applications that require easy deployment and minimal resource consumption.
PSQL
PostgreSQL is an open-source relational database known for its robustness and compliance with SQL. PSQL is also one of the most customizable databases, making it a suitable database for most applications. PSQL also complies with ACID (atomicity, consistency, isolations, durability) which increases its data reliability. PSQL is also quite crucial since it can run on various operating systems such as windows, Linux, and MacOS. This database is crucial for full-stack developers, data analysts, database administrators among others.
NoSQL databases
The NoSQL databases are an alternative to the traditional relational databases. These databases are crucial for handling unstructured data that is often evolving.
MongoDB
This is a document-oriented NoSQL database. This database uses the BSON format to organize collections and document these collections into different fields. This kind of database is a great choice for content management systems, e-commerce platforms, social media platforms, the Internet of Things (IoT), and other applications with ever-evolving schema requirements. MongoDB can be easily integrated with various programming languages, which means that as a student, you get to work with familiar technologies. Learning MongoDB in school is also quite crucial since there is an increased demand for professionals with MongoDB skills.
Cassandra
Cassandra is a distributed NoSQL database that is meant to handle large volumes of data. Cassandra is crucial in big data and real-time analytics applications since these applications require scalability, fault tolerance, and high availability. Cassandra has a masterless architecture, meaning that there is no possibility for failure, a crucial requirement for most applications. Learning Cassandra allows a student to design systems that can withstand any kind of hardware and network failure. Cassandra can also easily handle time series data, which is crucial for applications that use data that changes over time. Learning Cassandra can also help a student to learn how deploy, monitor, and manage databases in the cloud. Like other NoSQL databases, Cassandra can provide you with excellent job opportunities in the data-driven world.
Redis
Redis is an in-memory NoSQL database that is known as a key-value store. This is a great database for caching, session management, and real-time data processing. Redis has exceptional speed, meaning that it can easily handle high loads. More than that, it can also be used as a standalone database and it can also be used as a cache, working as a front for the traditional database. Learning Redis can help you to learn how to design systems for high-performance data storage. It can also teach you how to leverage in-memory databases for applications requiring rapid data retrieval. Learning Redis can also help a student make the right decisions when it comes to trade-offs between performance and data safety.
Graph database
This is a kind of NoSQL database that stores and manages data as a graph. In a graph database, data is represented as nodes, edges, and properties. This makes graph databases crucial when it comes to dealing with complex relationship modeling such as social networks, recommendation engines, and fraud detection. Graph databases can be used in various applications, making it such a valuable tool for students to learn. This skill is also crucial since it will put you in the front seat of emerging trends. Learning graph databases will help you tap into opportunities for innovation and startups, which will only help enhance your career prospects.
Final thought
The database you learn in school is not just for fun, which means that you need to be careful about the database you choose to learn. Learning a database is a crucial part of your academic and professional journey. The right choice of database will depend on your career goals, your academic interests, and even your academic field. You can choose to either go the traditional way with the SQL databases or the unconventional way with the NoSQL databases. Whichever database you choose, remember that the world of technology is ever-changing, meaning that you need to be quite adaptable to any changes that come your way. One of the changes that you need to be adaptable to is learning more than one database. Keeping an open mind can help you explore various databases since you need to be diverse in the data world. The good news is that as you begin your database learning journey, Paper per Hour will be with you every step of the way, helping pick up the slack when things seem a bit tough for you.
