The spelling of the term "contained database" can be explained through its International Phonetic Alphabet (IPA) transcription. The first sound is the "k" sound (/kənˈteɪnd/), followed by the "t" sound (/t/). The middle syllable includes the "ei" sound (/eɪ/) and the "n" sound (/n/). The final syllable starts with the "t" sound (/t/) and then has the "ɪdʒ" sound (/dʒ/), followed by the "b" sound (/b/) and ending with the "eɪs" sound (/eɪs/). This spelling represents the English pronunciation of the term.
A contained database refers to a self-contained unit within a database management system that encapsulates all the necessary information, data, and metadata required for its proper functioning. It is a concept implemented in modern database systems to enhance portability, scalability, and security.
In a contained database, all the essential elements are stored within the database itself, including data files, log files, and security credentials. This implies that the database can be easily moved or deployed across different instances or platforms without the need for external dependencies or configurations. Consequently, contained databases are highly portable and can be readily shared or copied among different environments.
Contained databases are designed to be self-sustaining, meaning they can function independently without relying on external resources or specifying server-level configurations. This allows for seamless migration and deployment of databases across different systems and ensures consistent behavior regardless of the hosting environment.
Furthermore, contained databases offer enhanced security by isolating their resources and metadata within a well-defined boundary. By encapsulating database credentials and access controls, contained databases reduce the risk of unauthorized access and improve data privacy. This isolation also simplifies the management of user permissions and reduces potential misconfigurations or conflicts with other databases or server settings.
Overall, a contained database is a self-contained and portable unit that offers increased flexibility, security, and consistency, making it a valuable feature in modern database management systems.
The etymology of the term "contained database" can be traced back to the combination of the words "contain" and "database".
- "Contain" originates from the Latin word "contenere", which means "to hold together". It evolved into the Old French word "contenir", which means "to hold or contain". This led to the Middle English word "conteinen", which has the same meaning.
- "Database" is a combination of the words "data" and "base". "Data" comes from the Latin word "datum", which means "thing given". "Base" traces back to the Old French word "bas", meaning "low or lowly".
When these words are combined, "contained database" refers to a self-contained or self-sufficient database that is isolated and independent from external dependencies, making it easier to manage, move, and deploy.
