    • A method and system are disclosed for efficiently storing and viewing data in a database. Data is stored in a nested data model which includes a plurality of nodes. A plurality of edges connect the plurality of nodes. Each edge has a unique edge name. A plurality of instances of data objects are associated with the nested data model. Each instance is associated with one of the edges such that the instance is also associated with that edge's name. An instance ordinal is associated with each instance which represents the number of times the edge associated with each instance is encountered during a traversal of the nested data model. The data stored utilizing the nested data model is accessed utilizing the instance ordinal and edge name associated with each of the plurality of instances, such that the data is accessed as being flat without flattening the nested data model.
    • 公开了一种用于在数据库中有效地存储和查看数据的方法和系统。 数据被存储在包括多个节点的嵌套数据模型中。 多个边缘连接多个节点。 每个边缘都有一个独特的边缘名称。 数据对象的多个实例与嵌套数据模型相关联。 每个实例与其中一个边缘相关联,使得实例也与该边缘的名称相关联。 实例序数与每个实例相关联,表示在遍历嵌套数据模型期间遇到与每个实例相关联的边的次数。 使用嵌套数据模型存储的数据使用与多个实例中的每个实例相关联的实例序数和边缘名称被访问,使得数据被访问为平坦而不使嵌套数据模型变平。
