摘要:
A logging method of reducing a log size by using a log entry when a log record is generated by an update, and an apparatus therefore, is provided. The method includes storing log information of a data page being updated; when the update of the data page is completed, reading the stored log information; generating a log record by using the read log information; and writing the generated log record in a log page. According to the method, the log size due to logging is reduced and the times of disk input and/or output operations decrease, thereby improving the updating speed of a database system.
摘要:
A system and a method for managing log information. The system includes an input module that receives log information on a data renewal and a control module that stores a renewed data image based on the received log information when a page area where the renewed data exists is a hotspot, wherein the control module manages a hotspot control list (HSCL) including hotspot managing information and address information on a storage area in which the renewed data image is stored.

Provided are an apparatus and method of componentizing a legacy system that reconstructs software components, which are included in the legacy system, as abstract or logical modules according to the association between the components. An apparatus for componentizing a legacy system includes a legacy code analyzing unit which analyzes the association between one or more legacy codes, which are included in the legacy system, a component generating unit which generates data for defining one or more components by referring to the analyzed association, a component analyzing unit which analyzes the association between the components, and a data updating unit which updates the data by referring to the association between the components.
摘要:
A method and system for contextual association discovery to conceptualize a user query. The system includes a user input unit receiving an input of a user query from a user, an attribute extraction unit extracting one or more attributes that materialize the meaning of the input query, a related attribute selection unit selecting one or more related attributes among the extracted attributes, and a content classification unit classifying specified content in accordance with the selected related attributes and the query.

摘要:
Provided are a distributed file system and a method of replacing cache data in a distributed file system capable of replacing cache data based on the degree of network instability between a server and a client. The method includes monitoring network instability between the first apparatus and the second apparatus, determining whether an empty space exists in a storage space of the second apparatus if the second apparatus needs data of the first apparatus, if an empty space does not exist in the storage space, deleting at least one cache data item already stored in the second apparatus according to the monitored network instability, and storing data obtained from the first apparatus in the empty space generated by deleting the cache data.

摘要:
An apparatus and method for developing component-based software, and more particularly, an apparatus and method for developing component-based software in order to define an identified component in a component language and reuse the identified component. The apparatus includes a component division module to analyze source code and a build file and to divide the analyzed source code and build file into a build-level component and a functional-level component; an integrity check module to check the integrity of languages defining the build-level component, the functional-level component, and an interface of the functional-level component; and a component combination module to combine one or more build-level components corresponding to one or more functional-level components that form an architecture.
