A request is issued in order to duplicate the items including the necessary data on a data replication list on order. The data replication request is inputted in a processing list and the data replication process proceeds. Upon a processing completion signal, the request is deleted from a queue and a meta database is renewed reflecting the result of the completed data replication process.

Abstract: PURPOSE: A query defining device for multitenant support and a method thereof are provided to easily define queries about an extended schema only with the selection of a specific item by providing a query defining interface to a tenant manager. CONSTITUTION: A schema generating unit generates a basic schema for executing an application requested by a tenant on an SaaS(Software as a Service) platform. A schema editing unit(20) edits the basic schema according to a request of a tenant manager. If the basic schema is edited, a query defining unit(30) provides a query defining interface for the edited schema to the tenant manger and extracts a corresponding query according to the manipulation of the query defining interface in order to define the query. The query defining interface defines queries corresponding to each item implemented in the interface. [Reference numerals] (10) Schema defining unit; (20) Schema editing unit; (30) Query defining unit; (40) Query processing unit; (50) Manager interface
Abstract translation: 目的：提供用于多租户支持的查询定义设备及其方法，用于通过向租户管理器提供定义界面的查询，来容易地定义关于扩展模式的查询，只要选择特定项目即可。 构成：模式生成单元生成用于执行SaaS（软件即服务）平台上租户所要求的应用程序的基本模式。 模式编辑单元（20）根据租户管理者的请求编辑基本模式。 如果基本模式被编辑，则查询定义单元（30）向租户管理器提供用于编辑的模式的查询定义界面，并且根据查询定义界面的操纵提取对应的查询以定义查询。 查询定义接口定义与接口中实现的每个项目相对应的查询。 （附图标记）（10）模式定义单元; （20）模式编辑单元; （30）查询定义单元; （40）查询处理单元; （50）管理界面

Abstract: PURPOSE: An SaaS(Software as a Service) platform and a service provisioning method for multiple tenant support by using the same are provided to guarantee the provision of an independent service by providing a service by using an SaaS platform based on metadata. CONSTITUTION: A setting environment module(11) sets an environment for converting tenant setting information into metadata. A metadata manager(13) manages tenant metadata and application data. When a service request is received from a tenant user, an execution engine module(12) requests metadata of a corresponding tenant to the metadata manager and generates and provides a service by loading the metadata. A metadata database(14) stores the tenant setting information set by the setting environment module. An application database stores application data to be provided to the tenant user. [Reference numerals] (1) SaaS platform; (11) Setting environment module; (12) Execution engine module; (13) Metadata manager; (14) Metadata DB; (15) Application data DB

Abstract: PURPOSE: An on-line application providing device and a method thereof are provided to support tenants with a single application instance by changing the application to be suitable for each tenant using metadata. CONSTITUTION: A configuration unit(120) receives tenant environment information from a tenant manager. A metadata manager(140) creates the metadata of the tenant and stores the created meta data based on the received environmental information. The metadata manager detects metadata corresponding to the tenant of the user terminal. A service provider(160) individualizes the on-line application to the tenant of the user terminal using the detected metadata.
