Embodiment Construction

[0025] Next, an embodiment of the management device of the present invention will be described in detail with reference to the drawings. However, in this embodiment, an example in which the management device is embedded in an embedded device such as a digital home appliance will be described.

[0026] figure 1 It is a block diagram showing an example of the configuration of the management device 1 of this embodiment. Such as figure 1 As shown, the management device 1 includes: an instruction unit 10, a transaction unit 20, a stream generation unit 30, a buffer control unit 40, a segment processing unit 50, a stream storage unit 60, a temporary storage unit 70, and a log storage unit 80 .

[0027] The instructing unit 10 receives a stream data registration request from an upper layer not shown, and instructs the office unit 20 to start a transaction, or instructs the stream generating unit 30 to register the stream data. In addition, the instructing unit 10 instructs the tr...

Abstract

According to an embodiment a management apparatus includes: a stream storage configured to store a stream constituted by a plurality of pages; a trace information storage configured to store trace information in each stream, a receiving unit configured to receive a request to write the pages constituting the stream; and a management unit. The management unit refers to the trace information; writes the page into the stream storage when the write rule indicates that the page is to be written in the stream storage; writes the page into the temporary storage when the write rule indicates that the page is to be written in the temporary storage; and writes the page that has been written in the temporary storage into the stream storage in units of extents at a predetermined timing.

Description

technical field [0001] The present invention relates to management devices. Background technique [0002] In recent years, database management systems are also used in embedded devices equipped with large-scale storage (storage), such as digital home appliances. In such an embedded device, although the capacity of the main memory is also increased, the capacity is on the order of several KB to several MB, processing can only be performed within a limited resource range, and registration performance and update performance are not so high. [0003] As a technique for coping with insufficient capacity of the main memory, for example, Patent Document 1 discloses a technique related to a shadow page method using a mapping table for recording DB files and temporarily holding page units. The temporarily written file of the updated data of , and the list of updated pages temporarily written in the file. [0004] prior art literature [0005] patent documents [0006] Patent Docu...
