Abstract: Disclosed are an electronic device and a non-transitory computer-readable storage medium. Conventionally, most of institutions, companies, etc. have defined and used their own data standards for the business purposes. Most of the data is stored in relational database in a structured format. Now as convergence between industries, new business and new data increases, an active data management system is becoming necessary. The electronic devices according to the disclosure can provide data hub device providing automatically extendable data management function interworking with an open data reference model management device (an active metadata management). Accordingly, the data hubs can exchange standardized data maps among them so as to quickly adapt to such changes in the open industry environment.

Abstract: A system for recommending data analysis services is provided. The system comprises: a service catalog storing a list of analysis services; a data catalog storing a list of data of targets for analysis; an algorithm catalog storing a list of analysis algorithms; an interactive analytic tool receiving a user requirement in a word form; an analysis helper receiving the user requirement and extracting an analysis service corresponding to the user requirement from the service catalog; an analysis job generator receiving the user requirement, extracting data and an analysis algorithm corresponding to the user requirement from the data catalog and the algorithm catalog, respectively, and defining the extracted data and the extracted analysis algorithm to one job to generate a job, wherein the analysis job generator transmits the generated job to the analysis helper to deliver the job as recommendation analysis service information to a user through the interactive analytic tool.

Abstract: Disclosed herein are an apparatus and method for providing an application for processing big data. The apparatus includes a setting unit, a unified information access unit, a metadata management unit, and a database unit.

Abstract: Disclosed are an apparatus for supporting continuous read/write in an asymmetric storage system, and a method thereof are provided. The apparatus for supporting continuous read/write in an asymmetric storage system that permits continuous reading/writing by providing context identifiers for reading or writing files and requesting reading or writing the files, using the context identifiers. Therefore, it is possible to efficiently process continuous reading or writing, improve performance of data service, and reduce waster of a memory by removing context identifies for reading or writing files when the files are not used any more or not frequently used.
