This tag is for issues pertaining to databases that are embedded in an application.
The term "embedded" is used to characterize databases that were built to support exactly one application. There are other usages of "embedded", but this is the main one. When a database is embedded in an application, the requirements on the database are driven by the overall requirements on the application.
Questions arise about whether the design principles for databases in general apply to databases that are embedded in one application. There are also questions that arise about when and how embedded databases ought to be administered, and about whether access to the data via a language like SQL ought to be allowed or denied.
When a question about databases applies specifically to an embedded database, this tag will group the question together with other similar questions.
