Databases

In-memory database

An in-memory database (IMDB) is a type of database system that stores and manages data primarily in the system's main memory (RAM), rather than on disk or other storage devices. This allows for extremely fast data access and retrieval, as there is no need to read from or write to a physical disk.

CrateDB

CrateDB is a distributed SQL database management system that integrates a fully searchable document-oriented data store.

CRUD

Create, Read, Update, Delete. The acronym CRUD refers to all of the major functions that are implemented in relational database applications. CRUD is also sometimes used to describe user interface conventions that facilitate viewing, searching, and changing information; often using computer-based forms and reports.

CSV

A simple file format used to store tabular data. CSV is supported by a huge number of tools, from spreadsheets like Excel, OpenOffice and Google Docs to complex databases.

Database

A collection of digital information, that is organized in such a way that it can be easily managed. The information is stored and processed on a computer with or without human assistance. Traditional databases are organized by areas, records, and files.

Database as a Service

Database as a Service (DBaaS) is a cloud computing service model that provides users with access to a fully managed database system. In this model, the cloud service provider takes care of all the administrative tasks related to database management, including maintenance, backups, updates, and scaling. Users can focus on utilizing the database for their applications without the need to worry about the underlying infrastructure or operational tasks.

Database administration

Database administration is the function of managing and maintaining database management systems software.
