Types of Databases

This work presents a concise and visually structured mind map of different types of databases, classified on the basis of data types, data models, database distribution, number of users, and data usage. It covers major database categories such as structured, semi-structured and unstructured databases; centralized, distributed, homogeneous and heterogeneous databases; single-user and multi-user databases; and data models like relational, hierarchical, network, object-oriented, and multidimensional databases. The mind map also includes operational, transactional, analytical, and production databases based on usage. This resource is useful for students, teachers, researchers, and library & information science (LIS) learners for quick understanding, revision, and academic presentation purposes.
