Types of databases: a guide for data enthusiasts

This article provides an overview of ten types of databases, including their features, applications, and strengths. These include relational databases (MySQL, PostgreSQL, Oracle, Microsoft SQL Server), NoSQL databases (document model, key-value, columnar, graph, time-series), in-memory databases (Redis, SAP HANA, Memcached, Oracle TimesTen), NewSQL databases (Google Spanner, CockroachDB, NuoDB), and object-oriented databases. Each type of database is designed to handle specific data structures and requirements, such as managing relationships in graph databases or efficiently processing time-stamped data in time-series databases. The choice of a suitable database depends on the nature of the data and the application's needs.
