Context: <response>: Database storage na di container wey dey hold di physical materialization of a database. E comprise di internal (physical) level for inside di database architecture. E also contain all di information wey dey needed (e.g., metadata, "data about di data", and internal data structures) to reconstruct di conceptual level and external level from di internal level when e dey necessary. Putting data into permanent storage na generally di responsibility of di database engine wey dem dey call "storage engine". Though typically accessed by a DBMS through di underlying operating system (and often utilizing di operating systems' file systems as intermediates for storage layout), storage properties and configuration setting dey extremely important for di efficient operation of di DBMS, and so dem dey closely maintained by database administrators. A DBMS, while e dey operation, always get im database wey dey stay for different types of storage (e.g., memory and external storage). Di database data and di additional needed information, possibly for very large amounts, dey coded into bits. Data typically dey stay for di storage for structures wey dey look completely different from di way di data dey look for di conceptual and external levels, but in ways wey dey try optimize (the best possible) di reconstruction of these levels when e dey needed by users and programs, as well as for computing additional types of needed information from di data (e.g., when querying di database).
