Define the term in-memory database and explain its advantages in processing big data In-Memory Database

In-Memory Database

A database which stores data in the main RAM (or memory) of a computer is an in-memory one. This differs from a disk-based, where data is stored on a hard drive. In-memory data bases are made to handle large quantities of data efficiently and quickly. This is in contrast to disk-based databases that store data on a hard drive. Accessing data from the main RAM is much quicker than using a hard-drive. In-memory database are well-suited to real-time analytics and data processing. These databases are able to handle large quantities of data, without the need for complicated indexing or partitioning that can prove costly and time-consuming with disk-based database. In-memory database are ideal for managing large datasets quickly and data from many sources. For example, “In-memory databases can achieve faster query performance and handle larger data volumes with fewer servers, which can reduce hardware, software, and maintenance costs” (Günther, Neumeier, & Lehner, 2015).
