Abstract: Authentication and authorization can be performed with a bundled token, which encapsulates two or more security tokens in a single security token. The bundled token can be supplied in response to a request for a token from a token service, for example. Subsequently, the bundled token can be sent in conjunction with a request for resource access, wherein more than one token is required to access the resource.

Abstract: A system, method, and computer program product are provided for determining at least potentially duplicate records. In use, when a new record is received, a first entry of a first predetermined field of the newly received record is identified, and a data structure is selected, based on the first entry. Further, a second entry of a second predetermined field of the newly received record is identified, and the second entry is compared to entries already stored in the data structure, where the entries stored in the data structure are associated with a plurality of other received records. Still yet, it is determined whether the newly received record is at least potentially a duplicate of at least one of the other received records, based on the comparison.

Abstract: A system, method, and computer program are provided for sending a response to a client based on a replication message received from a master server. In use, a replication message is received at a replication server from a master server. Further, a response is sent from the replication server to a client based on the replication message received from the master server.

Abstract: A data structure, method, and computer program provide a linked list in a first dimension and a plurality of linked lists in a second dimension. In use, a linked list in a first dimension is provided. Further, the linked list in the first dimension includes a plurality of nodes. Additionally, each node includes a head pointer and a tail pointer. In addition, a plurality of linked lists in a second dimension is provided. Furthermore, the tail pointer of one of the nodes in the linked list in the first dimension points to a first node in one of the linked lists in the second dimension.
