Description: An intermediary database is a temporary storage system that facilitates the transfer of data between different systems or applications. Its main function is to act as a bridge that allows for the integration and exchange of information efficiently. These databases are particularly useful in environments where data needs to be processed or transformed before being sent to its final destination. They are often used in software architectures that require the collection of data from multiple sources, allowing data to be temporarily stored for later analysis or processing. Intermediate databases can handle large volumes of data and are capable of supporting simultaneous read and write operations, making them ideal for real-time applications. Additionally, they tend to be flexible and scalable, allowing organizations to adapt to changing data needs. In the context of NoSQL, these databases can leverage non-relational data structures, enabling them to manage semi-structured or unstructured data more efficiently. In summary, intermediary databases are crucial components in modern data architecture, facilitating interoperability between systems and improving efficiency in information handling.
