The demand for real-time analytics is also driving convergence between databases and streaming platforms. The result is a new generation of databases that can ingest and query live data simultaneously, blurring the line between storage and processing.

: Specialized requests sent to the database (usually via structured languages) to filter, insert, modify, or delete data. 2. The Great Divide: SQL vs. NoSQL The demand for real-time analytics is also driving

The first databases used tree-like structures (hierarchical) or web-like structures (network). While innovative, they were rigid. If you wanted to query the data in a way the original structure didn't anticipate, you were out of luck. While innovative, they were rigid

The first relational database management system (RDBMS) was developed in the 1970s by Edgar F. Codd, a British computer scientist. Relational databases, such as IBM's System R and Oracle's Oracle Database, organized data into tables with well-defined relationships between them. This approach provided a structured way to store and manage data, supporting complex queries and transactions. (Examples: Apache Cassandra

Not all databases are created equal. The term "DB" encompasses dozens of different architectures, each optimized for specific use cases. Here are the primary categories:

Organize data into flexible columns rather than rows, optimizing them for large-scale analytical queries. (Examples: Apache Cassandra, ScyllaDB).
