NoSQL databases are a class of database management systems that provide a mechanism for storage and retrieval of data modeled in means other than the tabular relations used in relational databases. They are particularly useful for handling large volumes of unstructured or semi-structured data and are designed to scale horizontally across many servers.

Database Management Systems (DBMS) are software systems that use a standard method to store and organize data, allowing users to perform multiple tasks with ease and efficiency. They provide a systematic way to create, retrieve, update, and manage data, ensuring data integrity, security, and consistency across applications.

storage and retrieval of data

Unstructured data refers to information that does not have a predefined data model or is not organized in a pre-defined manner, making it challenging to analyze using traditional data processing methods. It includes diverse formats like text, images, video, and social media posts, requiring advanced techniques like natural language processing and machine learning for meaningful insights.

Unstructured Data

Semi-structured data is a form of data that does not conform to a rigid schema like structured data, but still contains tags or markers to separate data elements, providing a level of organization. It is often used in scenarios where flexibility is needed, such as in XML or JSON formats, allowing for easier data exchange and integration between systems.

tabular relations

Relational databases are structured systems that store data in tables with rows and columns, using a schema to define relationships between different data entities. They enable efficient data retrieval and manipulation through SQL queries, ensuring data integrity and consistency using ACID properties.

Data modeling is the process of creating a visual representation of a system or database to illustrate the relationships between different data elements. It is essential for designing databases, ensuring data integrity, and facilitating communication between stakeholders and developers.
