Schema-less databases

Schema-less databases, often called NoSQL databases, are designed to store and manage data without a fixed structure or format. Unlike traditional databases that require a predefined schema (a detailed blueprint of data organization), schema-less databases allow users to store various types of data together, such as documents, key-value pairs, or graphs. This flexibility enables developers to adapt to changing data requirements easily and quickly. As a result, schema-less databases are particularly useful for handling large volumes of diverse and unstructured data, making them popular in modern applications like social networks and big data analytics.
