At least one integrated server is installed between a plurality of terminal devices and service servers of a plurality of types. A session establishment processing unit and service linking processing unit are mounted in the integrated server. The session establishment processing unit establishes multimodal service session between terminals and service servers. After the establishment of multimodal service session, the service linking processing unit provides new service obtained by linking and integrating service to be provided by service servers, that is, multimodal service to terminal devices.

Abstract: The database system of the present invention decides a fragment length responding to a unit of a data process of a parallel arithmetic unit, and stores tuple data containing variable-length data into a fragment and metadata of the fragment into a fragment header, respectively, in a column store database. The database system refers to the metadata when executing a process for data stored in the column store database, decides the fragments to be assigned to each thread that is executed by the parallel arithmetic unit, assigns the fragments to each thread based upon the decided content, and causes each thread to execute a parallel arithmetic operation.

Abstract: Provided is a non-shared type database system capable of efficiently manipulating data in a distributed database. A distributed database management system has a query receiving unit (load balancer) that receives a query; and, plural storage processing units that manipulate data in the distributed database in a cooperative manner on the basis of the received query. Each of the storage processing units includes: a storage device that stores one of partial databases constituting the distributed database; and, a data manipulation unit that manipulates data in the partial databases stored in the storage device on the basis of the received query.

Abstract: Provided is a database system capable of efficiently and rapidly updating data in a database. The database system has a data processing unit that performs, to the database, data processing base on a query. The database includes an identifier table storing data identifiers each having a fixed length and uniquely representing entity data themselves and a conversion table. The conversion table shows a correspondent relationship between the data identifiers and position data each indicating a position of a storage area of the entity data. The conversion table has a metadata area Fidx, and the metadata area Fidx stores a tuple identifier uniquely designating a tuple that stores each of the data identifiers in the identifier table.
