Abstract: It is provided a method and system for selectively separating organization for generating a second database by copying a first database, selecting data by mapping a condition of a deletion subject to a business object of the second database, extracting the selected data from the second database and saving it as a file, and generating a third database to be transferred by deleting data matched with the read data from a table in the second database.

Abstract: Provided are a data processing method and apparatus capable of rapidly searching for data compressed and stored in non-volatile storage means by compressing a data record, stored in a volatile in-memory database, in a partition unit, storing the compressed data record in the non-volatile storage means, and storing, in a table of the volatile in-memory database, a storage key to uniquely identify each of partitions stored in the non-volatile storage means and sorting information used to determine a partition for a data record.

Abstract: Provided are a data archiving method and system capable of reducing the cost of transmitting and retrieving archived data by determining a transmission capacity or a retrieval capacity according to at least one of a characteristic of a storage system and a charging system in a process of transmitting at least some of data stored in a target system for archiving to the storage system or in a process of retrieving data archived in the storage system.

Abstract: Disclosed are a method and system for selecting target data. The method of selecting target data may include steps of grouping data included in a database into objects each being a minimum process processing unit based on dependency between tables within the database, setting a selection criterion for target data based on at least one field of the data included in the database, and extracting target data corresponding to the set selection criterion by taking into consideration dependency between tables included in the object.

Abstract: A method and system for selective transfer of organizational data in case of a divestiture are disclosed. The method includes: exporting a system architecture for a first database of a first organization from a first database of the first organization including data intended for migration from the first organization to a second organization; creating a second database of the second organization, which is a target database to which the intended data is to be transferred, in a system of the second organization by importing the exported system architecture to the system of the second organization; extracting the intended data from the first database; and sending the extracted intended data to the second database of the second organization.

Abstract: There are provided a data archiving method and system, which can process primary archiving capable of rapidly searching for compressed and stored data by compressing and storing, in a table of a database or another database, at least some of data stored in the database included in a target system, and can process secondary archiving for data for which search is no longer requested or for which a search request is low by storing at least some of the data compressed and stored in the table in the form of a file according to a preset condition.

Abstract: Provided is a database archiving method. According to the exemplary embodiment of the present invention, a database archiving method includes: selecting at least one record group including a plurality of records from an original table from which data is archived, based on selection information on at least one of a time and a field value; storing group compression data compressed to be created for every record group and the selection information corresponding to the group compression data in a compression table, with respect to each of at least one selected record group; and deleting a plurality of records included in at least one selected record group from the original table.

Abstract: Provided is a database archiving method for creating index information. According to the exemplary embodiment of the present invention, a database archiving method for creating index information includes selecting at least one record group including a plurality of records from an original table in which data is archived, based on information on a field value; storing group compression data compressed to be created for every record group and a stored key value uniquely assigned to every group compression data, with respect to each of at least one record group, in a compression table; storing the field value and the stored key value corresponding to each of at least one record group, in a group index table; and deleting a plurality of records included in at least one selected record group from the original table.
