Controlling access to a database using database internal and external authorization information

Abstract

Techniques for using both database internal and database external authorization information to control access to a database are disclosed. Corporate accounts which are generally used in many corporate environments (e.g., operating system accounts) can be defined as “external” database accounts with database external authorization information that define database external access privileges for a database. The database external access-privileges are used in conjunction with a set of complementary database “internal” access privileges defined for database internal accounts. An integrated access-privilege set is generated and used as a single source to authorize access to a database regardless of whether database internal or external accounts are used to access the database. As a result, databases can be integrated with various non-database entities (e.g., corporate computing systems).

1 . A computer-implemented method of controlling access to data stored in a computer readable storage medium of a database system that includes a computing system, wherein said computer-implemented method comprises:
 obtaining, by said computing system, external authentication data indicative of an external authentication identifier, wherein said external authentication identifier is associated with a database external account defined for an external system external with respect to said database system;   obtaining, by said computing system, authorization data associated with said authentication data and stored on a computer readable storage medium of said database, wherein said authorization data includes group matching data indicative of one or more group identifiers defined for database external accounts including said database external account;   obtaining, by said computing system and based on said authorization data, an integrated access privilege set that includes both: (a) database external authorization information and (b) database internal authorization information, wherein said database external authorization information (a) includes a plurality of group identifiers each of which are associated with one or more defined access-privileges for accessing said database by said database external accounts, and wherein said database internal authorization information (b) includes a plurality of database internal authentication identifiers that are each associated with one or more defined access-privileges for accessing said database; and   determining, by said computing system and based on said integrated access privilege set, whether to allow access by effectively using said one or more group identifiers or by effectively using said one or more database internal authentication identifier, thereby effectively allowing access with appropriate access privileges as a database external account based one or more matching group identifiers defined for database external accounts or as a database internal account with one or more database internal authentication identifiers defined for database internal accounts of said database.
