  • Publication number: 20230418826
    Abstract: A computer system for searching for a candidate for an environment in which an object is to be deployed, the computer system is coupled to a plurality of infrastructure systems each of which provides the environment. The computer system receives a search request including an environmental requirement being a condition required for the environment in which the object is to be deployed and a constraint being a condition to be complied with in deployment of the object; executes first environment search processing for searching for the environment that satisfies the constraint and the environmental requirement; changes the environmental requirement in a case where the environment in which the object is deployable does not exist; and executes second environment search processing for searching for the environment that satisfies the constraint and the changed environmental requirement.

  • Patent number: 11650988
    Abstract: The database management system (DBMS) receives a first instruction specifying anonymization rule information corresponding to a column of the relation table, among anonymization rule information that is present for each column included in the relation table and shows a plurality of generalization rules. The DBMS reads the column from the relation table in response to the first instruction, and generates a temporary result obtained by generalizing each attribute value of the column based on any of a plurality of generalization rules. The DBMS generates an aggregate result obtained by aggregating the temporary result. The DBMS generates an anonymization method including generalization information indicating a correspondence relationship of each attribute value of the column and any of the plurality of generalization rules when the aggregate result satisfies a disclosure rule. The DBMS generates anonymization information as a result of processing the relation table based on the first anonymization method.

  • Publication number: 20220358135
    Abstract: Systems and methods described herein involve a meta-graph management configured to link external data source to another external data mart through a data management platform which can involve managing characteristics of one or more tables of the data source and the data mart and a temporary table based on columns, managing characteristics of one or more Input data and Output data of data processing from the data source to the data mart based on columns; managing relationships of characteristics between data and data processing for the data source and the data mart based on the columns; managing one or more data flows between the data source and the data mart that include data, data processing, and relationships; and providing data, data processing, and relationships between the data source and the data mart for each data flow.

  • Patent number: 11176092
    Abstract: There is provided a database management system (DBMS) in order to make anonymization processing of the database efficient. When receiving a query including a conversion rule, the database management system is configured to process a relationship table in the database based on the conversion rule. At that time, the DBMS is configured to acquire data from a processing result table (result of processing the relationship table) stored in the past for tuples the number of which for each value appearing in a predetermined attribute satisfies a condition required for the anonymization processing. On the other hand, for tuples the number of which for each value appearing in a predetermined attribute does not satisfy the condition required for the anonymization processing, the DBMS is configured to acquire data from the database or from a result of processing the relationship table, the result being stored in rather than the processing result table.

  • Patent number: 11061907
    Abstract: If a query indicates joining of N (N is an integer of no less than 3) relation tables, a database management system calculates a query cost that is based on a power consumption amount for query execution, for each of a first query plan candidate in which a temporary table is generated and the temporary table is stored in a storage device unit with a first access cost, a second query plan candidate in which a temporary table is generated and the temporary table is stored in a storage device unit with a second access cost that is higher than the first access cost and a third query plan candidate in which the N relation tables are joined in a pipelined manner without generation of a temporary table, selects a relatively low-query cost query plan candidate and executes the query based on the query plan candidate.

  • Patent number: 10747446
    Abstract: Since storage devices are activated in the issuance order of I/O commands, the time required for processing of a plurality of I/O commands based on one or more I/O requests may become long. When issuance destinations of two or more I/O commands are two or more storage devices in a non-activated state from among a plurality of storage devices, a computer system determines an activation order of the two or more storage devices on the basis of two or more I/O quantities which respectively correspond to the two or more storage devices. Each of the I/O quantities of the two or more storage devices is an I/O quantity in accordance with one or more I/O commands for the relevant storage device from among the two or more I/O commands. The computer system activates the two or more storage devices in the determined activation order.
