NAME

elektra-glossary - glossary of Elektra Introduction Configurations contain user preferences or other application settings. Configuration storage makes this information permanent. The application will read the configuration at every start, but it is only stored if a user changes settings. Key databases are used because of these constraints. They can do fast key lookups and the keys can be structured hierarchically by defining separators in the key names. Unlike SQL databases, the key name is the only primary key; there are no foreign keys, and no query language exists. Global key database provides global access to all key databases of all applications in a system that wants to access a key database.
