Provided is a mechanism wherein key-value structure data are effectively combined, and dynamic changes in the data structure and amount of data are coped with flexibly, and wherein the throughput in frequent reading of simple tables is improved with this mechanism. A flexible data model is built by making a referring mechanism for referring to attributes, and a referred to mechanism wherein references to attributes are made, to be a "referring- referring" element and a "referred to referred to "element; making a component by sandwiching key-value-store structure data; and combining components having multiple attributes with each other, as a "referring referred-to" relationship. Furthermore, receiving search results as a key-value-store structure cache will contribute in simplifying accesses by conventional application programs to the aforementioned flexible data model, which by extension will contribute in making the whole application program more high-speed. [There is a continuation] [Subject] It is a Subject of this invention to offer the means to construct a more advanced, more complex system from which it is requested to unite a key-value structural date effectively, and to correspond to a dynamic in the data structure and volume of data flexibly. In this invention, 'Reference mechanism to refer to the attribute' and 'Referred mechanism because of the reference as the attribute' add to a key-value structural data. [Solution] This Key-Value structural data refers to another one towhich 'Reference mechanism to to the attribute' and 'Referred mechanism because of the as the attribute' are added as an attribute, and this data is referred to from another one to which 'Reference mechenism to refer to the attribute' and Referred mechanism because of the reference as the attribute' are added as the attribute. The problem is solved by such a mechanism's being offered. |
