APPARATUS FOR GENERATING DATA SCHEMA SUPPORTING MULTI TENENT

摘要

PURPOSE: Data schema generation device and method supporting multi-tenant are provided to reduce the waste of a disc by storing data in one general-purpose data table regardless of a user table. CONSTITUTION: A metadata manager(35) determines the number of columns of an universal data table on a basis of the number of columns of basic table schemas corresponding to tenant data, and generates the general-purpose data table according to the number of columns. A metadata generator(31) generates the metadata defining the column attribute information of the columns of the general-purpose data table. A database stores the tenant data and metadata. A tenant execution engine(33) processes the service requested from a tenant user.
