PURPOSE: A device for managing space-attribute data by using a space index, is provided to enable an integrated management of space data and attribute data, needed when constructing an internet of a desk top geographical information system, and enable to quickly search a space, in a relational database system of various business or non-business operated under various operation systems. CONSTITUTION: A device for managing space-attribute data by using a space index in a relational database system(60), comprises a space-attribute data integrated manager(10), an attribute table manager(20), a space index manager(30), and a space table manager(40). The space-attribute data integrated manager(10) classifies a space data research and an attribute data research by analyzing a demand of a application system, when the application system demand a search and reading of data through an internet. The attribute table manager(20) searches an attribute data stored in the relational database when the classification of the space-attribute data integrated manager is an attribute data search, and then transmits the search result to the space-attribute data integrated manager. The space index manager(30) divides if a space index operation or a space data search operation when the classification of the space-attribute data integrated manager is a space data search, and then extracts space index information in a file system in case of a space index operation and transmits a message in case of a space data search operation. And the space table manager(40) checks if the space data are a chain type by space index information extracted by the space index manager(30) and a message transmitted form the space index manager(30), and then transmits to the space index manager(30) by extracting a chain table and a dot table, or only a chain table according to the checked result.
