## Abstract

In an open environment, a consensus building means for maintaining dependability throughout the entire life cycle of a target system between stakeholders is provided, thereby appropriately operating the target system in accordance with the content of an agreement between the stakeholders. A consensus building support tool provides a support for consensus building through an argument regarding an ordinary operation state of a target system. History obtained in the process of the consensus building is recorded in a database layer as an agreement graph. A monitoring node tool detects deviation from the ordinary operation state of the target system based on an actual operation state of the target system and the agreement graph. A contract generating tool extracts information data regarding the consensus building from the agreement graph when the deviation from the ordinary operation state is detected in the target system.

## Claims

### Claim 1

A database system, comprising:
a consensus building unit configured to provide a support for consensus building through an argument regarding an ordinary operation state of a target system;
an agreement graph storing unit configured to store history obtained in a process of the consensus building as an agreement graph;
a detecting unit configured to detect deviation from the ordinary operation state of the target system based on an actual operation state of the target system and the agreement graph; and
an extracting unit configured to extract information data regarding the consensus building from the agreement graph when the deviation is detected in the target system.

### Claim 2 (depends on 1)

The database system according to claim 1,
wherein the consensus building unit generates the agreement graph as a base with a plurality of models that define the target system, and
wherein the respective plurality of models uniquely define a meaning of a word regarding the target system, uniquely define an effect of an operation regarding the target system, and uniquely correlate logical definition with physical definition of data regarding the target system.

### Claim 3 (depends on 1)

The database system according to claim 1, further comprising a document storing unit configured to correlate and store the agreement graph and a document regarding the target system generated through action of a plurality of stakeholders at plural stages constituting a life cycle of the target system.

### Claim 4 (depends on 1)

The database system according to claim 1,
wherein the agreement graph is accessed in bilateral cycles, which are made up of a change accommodation cycle for continuously changing the target system with respect to an objective of the target system or a change in an environment and a failure response cycle for handling a failure in the target system.

### Claim 5

A database system control method, comprising:
a consensus building procedure configured to provide a support for consensus building through an argument regarding an ordinary operation state of a target system;
an agreement graph storing procedure configured to store history obtained in a process of the consensus building as an agreement graph;
a detecting procedure configured to detect deviation from the ordinary operation state of the target system based on an actual operation state of the target system and the agreement graph; and
an extracting procedure configured to extract information data regarding the consensus building from the agreement graph when the deviation is detected in the target system.
