In the field of data science, data scientists have major roles and responsibilities in managing the data, and that is where databases become one of the important tools for the data scientists, which helps them by collecting all the structured and unstructured data of businesses, companies, governments, and so on.
Different types of databases are used by data scientists to manage their data, which is discussed in this article. Therefore, in this article, comprehensive knowledge has been provided about the databases and the top 7 databases that are in demand and will be mostly used by data scientists in 2024.
What is a Database?
A database is particularly defined as a collection of well-structured data that includes record details, files, and other types of important information for multiple purposes. The data that is being stored in the database is managed by the database management system (DBMS). They are used to store and manage large amounts of data, and the databases also provide support for data management and analysis.
Top 7 Databases for Data Scientists in 2024
There are multiple types of databases available that can be used in scientific organizations, businesses, and many other fields. Some of the popular databases for data scientists are mentioned below:

- It can integrate both transactional processing and data analytics.
- It allows similar running of all cores in a processor, which is mainly important in data science where there are general queries running.
- The server for PostgreSQL can include user-written code.
2. IBM Db2
IBM Db2 is another popular database that is used by data scientists to provide high performance and scalability. This database is used to store and manage structured data. It is a type of relational database management system that further helps in managing and improving data availability. Multiple organizations use this database, whether they are of larger or smaller sizes.
Key Features:
- IBM Db2 provides a data platform for both analytical and transactional operations.
- The main purpose of this database is to store, manipulate, and retrieve data and information.
- It includes an advanced SQL query feature engine and data warehousing types of features.
- Storage optimization, workload management tools, and in-memory computing features are provided by IBM Db2.
- This database consists of physical and logical structures, which the DBMS manages.
3. MySQL
MySQL is a popular database that is used by data scientists as it is an open-source relational database management system that is used to develop website applications. It is used to store the data in the tables that map to objects. It is one of the most widely used databases among all developers and scientists due to its features. This database also provides a database management system with querying and connectivity capabilities.
Key Features:
- With the help of MySQL, data scientists can store the data in an easily accessible format.
- It also helps to store anything from simple numerical data to large amounts of complex information.
- It is a highly scalable and flexible database that provides high performance and compatibility to its users.
- It provides security features such as authentication and authorizations to the data scientists.
- This database helps the data scientists collect, clean, and visualize the data.
4. SQLite
SQLite is another famous simple relational database system, and it has multiple advantages over the other relational databases as it doesn’t need any servers. This database is mainly used to develop embedded software for software developers on multiple devices, such as cameras, televisions, and so on. This database implements a self-contained serverless transactional SQL database engine. The SQLite database has different methods to develop, delete, and excess SQL commands.
Key Features:
- SQLite helps to empower and streamline the workflow.
- It is a portable database and also facilitates work on different databases at the same time.
- SQLite is a cross-platform DBMS, and it is also available on both UNIX and Windows.
- It assists the data scientists in iterating the data process.
- With the help of SQLite, data scientists can analyze unstructured and semi-structured data.
5. Elasticsearch
Elasticsearch is a type of distributed search engine that was built by Apache Lucene, and this database is mostly used for full text search, log analytics, business analytics, and security intelligence use cases. This database allows the data scientist to search, store, and analyze large volumes of data easily.
Key Features:
- This database provides robust analysis and machine-learning capabilities.
- This database provides high performance, scalability, and real-time analysis to the developers.
- It can provide real-time capabilities for big data.
- It is also used for log analytics, operational intelligence, business analytics, and so on.
- Elasticsearch helps data scientists store, analyze, and store large amounts of data.
6. Microsoft SQL Server
Microsoft SQL Server is a famous database management system that mainly stores and retrieves data that is needed by other software applications. It is an ideal database that is used for storing the required information, and it also manages the security of the stored data. This database mainly focuses on providing speed and efficiency to data scientists.
Key Features:
- It handles relational datasets, the SQL server, and can also handle unstructured data.
- The SQL Server database engine includes a variety of services for storing, processing, and securing data, replication, tools, and many more.
- This database helps in handling data integration, data warehousing, data replication, and reporting features.
- It is mainly compatible with Microsoft business intelligence products and Azure.
- The Microsoft SQL Server database is designed to handle big data projects in an organization.
7. Mongo DB
MongoDB is another famous database that is used by data scientists for developing scalable applications with evolving data schemas. It is a cross-platform tool that works well with unstructured data and provides for JSON-like storage. This database consists of a flexible data model that helps store the data and offers full indexing support. Therefore, due to its flexible data model, it is one of the most widely used databases.
Key Features:
- MongoDB is a scalable database that is designed to overcome the relational database approach.
- It provides high availability and also allows for performing operations on the grouped data.
- It consists of replication capabilities through which it can develop multiple copies of data and send these copies to multiple servers.
- MongoDB is a document-oriented and schema-less database that is written in C++.
- It supports load balancing, map reduction, and aggregation tools.
Conclusion
Databases are used by data scientists to manage structured and unstructured data. These data consist of various types of data, which include numbers, files, words, images, and words. These databases can also support a large range of activities, including data analysis, data management, and data storage. Therefore, in this article, detailed knowledge has been provided about the databases and the top 7 databases that will be used by data scientists in 2024.
