> Derby currently provides a very simple permissions scheme, which is quite
> suitable for an embedded database system. End users of embedded Derby do not
> see Derby directly; they talk to a application that embeds Derby. So Derby
> left most of the access control work to the application. Under this scheme,
> Derby limits access on a per database or per system basis. A user can be
> granted full, read-only, or no access.
> This is less suitable in a general purpose SQL server. When end users or
> diverse applications can issue SQL commands directly against the database,
> Derby must provide more precise mechanisms to limit who can do what with the
> database.
> I propose to enhance Derby by implementing a subset of grant/revoke
> capabilities as specified by the SQL standard. I envision this work to
> involve the following tasks, at least:
> 1) Develop a specification of what capabilities I would like to add to Derby.
> 2) Provide a high level implementation scheme.
> 3) Pursue a staged development plan, with support for DDL added to Derby
> first.
> 4) Add support for runtime checking of these privileges.
> 5) Address migration and upgrade issues from previous releases and from old
> scheme to newer database.
> Since I think this is a large task, I would like to invite any interested
> people to work with me on this large and important enhancement to Derby.
