Embodiment Construction

[0052] The present disclosure relates to a database system, including programming semantics that facilitate multi-process between different users or entities. In one example, the database can utilize relationships (eg, SQL), non-relationships (eg, NOSQL), graphics, or other types of database models. In some examples, the database can provide a centralized view of data accessed by multiple users (ie, copy data that is not associated with each user of the database). In other words, in some examples, the database may be a centralized database that does not use a distributed consensus protocol or a replication mechanism, so it is not a DLT. Therefore, as described below, the database can implement multi-party execution program with privacy and appropriate authorization, without being affected by some existing defects of the DLT. Access to data in the database can be provided by allowing users and applications to interact with data interactions included in the database and databases.

Abstract

A database system (1) and a method (100), comprising a database system memory (3) and at least a first database server (9). The database system memory (3) stores a database of data records (7) and shared program instructions (51) between first and second database users (21, 31). The shared program instructions (51) define a privacy model (13) comprising privacy restrictions (14, 23, 33) for the first and second database users (21, 31), respectively, and specify an authorization model (19) comprising a first set of authorizations (25', 35') that permit the first database user (21) to manipulate a first subset (27) of the data records consistent with the first user's privacy restrictions (23', 33') and a second set of authorizations (25'', 35'') that permit the second user (31) to manipulate a second subset (37) of the data records consistent with the second user's privacy restrictions (23'', 33''). The database server (9) includes a processor (11) configured to execute the shared program instructions (51), wherein the shared program instructions (51), when executed by the processor (11): (1) process (110) a transaction (53) submitted by the first or second database user (21, 31); (2) determine (120) whether the transaction (53) conforms to the privacy and authorization models (13, 19); and (3) if the transaction passes step 2, commit (130) the transaction (53) and manipulate (55) the first or second subset of data records (27, 37) consistent with privacy and authorization models (13, 19).

Description

Technical field [0001] The present disclosure relates to database systems and methods for processing transactions using a database system shared with multiple users. Background technique [0002] Business processes, such as multi-party business processes, difficult to implement in databases (such as SQL and NOSQL), especially when multi-process involves private business processes of database users. The database system has always been unsuitable to maintain privacy in the multi-process. Although state machines can be used to implement business models in the database system, state machine and database system access control cannot perform the following: (i) Naturally capture authorization required to evolve in specific constraints, (ii) models Privacy Constraint, (iii) Ensure that database system access control license can prove that database system users have responsible to delegate some of the multi-party business processes to other database system users, and (iv) to ensure that d...
