Abstract: A method, device, and non-transitory computer-readable storage medium are provided for efficiently registering a relational schema. In co-compilation and data guide approaches, a subset of entities from schema descriptions are selected for physical registration, and other entities from the schema descriptions are not physically registered. In the co-compilation approach, a first schema description references a second schema description, and the subset includes a set of entities from the second schema description that are used by the first schema description. In the data guide approach, the subset includes entities that are used by a set of structured documents. In a pay-as-you-go approach, schema registration includes logically registering entities without creating relational database structures corresponding to the entities. A database server may execute database commands that reference the logically registered entities. A request to store data for the entities may be executed by creating relational database structures to store the data.
Abstract translation: 提供了一种用于有效地注册关系模式的方法,设备和非暂时计算机可读存储介质。 在共同编译和数据指南方法中,选择了来自模式描述的实体的子集用于物理注册,并且来自模式描述的其他实体没有物理注册。 在共同编译方法中,第一模式描述引用第二模式描述,并且该子集包括来自第一模式描述使用的第二模式描述的一组实体。 在数据指南方法中,子集包括由一组结构化文档使用的实体。 在现收现付方式中,模式注册包括逻辑注册实体,而不创建与实体相对应的关系数据库结构。 数据库服务器可以执行引用逻辑注册实体的数据库命令。 可以通过创建关系数据库结构来存储数据来执行用于存储实体的数据的请求。
