    • A method and apparatus for generating references to a set of objects which reside in a plurality databases is described. Each object is associated with a table from a plurality of tables that are contained in the plurality of databases. An object id is associated with each object; the object id uniquely identifies the object relative to the objects in the set of objects. A table id is associated with each table; the table id uniquely identifies the table relative to tables in the plurality of tables. A table containing an object is located based on the table id associated with the table, and the object is located in the table based on the object id associated with the object. A table mapping is generated. The table mapping maps a set of tables to databases associated with the set of tables. The set of tables are from the plurality of tables. References to objects from the set of object are generated. Each reference comprises data that identifies an object. The reference contains data representing the object id of the referenced object, the object referred to by the reference. The reference also contains data representing the table id of the table containing the referenced object. An object is located based on the table mapping and the reference referring to the object. The table containing the object is located based on the data in the reference, the data representing the table id associated with the table containing the object.
    • 描述了一种生成对驻留在多个数据库中的一组对象的引用的方法和装置。 每个对象与来自多个数据库中包含的多个表的表相关联。 对象id与每个对象相关联; 对象id唯一地标识相对于对象集合中的对象的对象。 表id与每个表相关联; 表id唯一地标识相对于多个表中的表的表。 包含对象的表基于与表相关联的表id来定位,并且该对象位于表中,基于与对象相关联的对象id。 生成表映射。 表映射将一组表映射到与该组表相关联的数据库。 表的集合来自多个表。 生成来自该对象对象的引用。 每个引用包括标识对象的数据。 引用包含表示引用对象的对象标识的数据,引用对象所引用的对象。 该引用还包含表示包含引用对象的表的表id的数据。 基于表映射和引用对象的引用来定位对象。 包含对象的表根据引用中的数据定位,表示与包含对象的表相关联的表id的数据。

    • A method and apparatus for presenting and modifying data from a set of tables in a database is provided. A view that is defined is based on a set of one or more tables that may include relational tables or object tables. The view defines a presentation of data from the one or more tables as a set of objects that reside in the database. Data is read from the one or more rows of the tables based on the view, and is presented as a set of objects that reside in the database. An object id that is based on data from the one or more rows is generated and associated with each object presented. The view may specify which columns from the one or more tables contain values used to generate the object ids. A trigger may associated with the view. The set of objects presented may be presented as objects having an attribute that is a column object. Column objects include user specified object types, collection objects (e.g. nested tables and variable arrays), or references to objects.
    • 提供了一种用于从数据库中的一组表格呈现和修改数据的方法和装置。 定义的视图基于可以包括关系表或对象表的一组或多个表的集合。 该视图将来自一个或多个表的数据的呈现定义为驻留在数据库中的一组对象。 基于视图从表的一行或多行中读取数据,并将其呈现为驻留在数据库中的一组对象。 基于来自一行或多行的数据的对象id被生成并且与呈现的每个对象相关联。 视图可以指定一个或多个表中的哪些列包含用于生成对象ID的值。 触发器可能与视图相关联。 所呈现的对象集可以被呈现为具有作为列对象的属性的对象。 列对象包括用户指定的对象类型,集合对象(例如嵌套表和变量数组)或对象的引用。

    • A method and apparatus are provided for handling within a database system data items that are associated with data types whose native structure is not known to the database system. The data items are stored within the database system in their native structure, even though it is not understood by the database system. To store the data items, the database system calls a pickling routine that is provided by the user, or by the runtime subsystem of the programming environment that is native to the data item. To retrieve the routine from storage, the database system calls an unpickling routine, also provided by the user or the appropriate runtime subsystem. Because the database maintains the data items in their native format, no conversions are required as the data items are passed between the database system and external routines that manipulate the data items. Techniques are also provided for declaring attributes of the data item that can be accessed within the database system. The user provides routines for the database system to call in order to access the declared attributes, which may be different than the actual attributes that the data item has in its native environment.
    • 提供了一种方法和装置,用于在数据库系统内处理与其本身结构对于数据库系统不知道的数据类型相关联的数据项。 数据项以其本机结构存储在数据库系统中,即使数据库系统不了解。 为了存储数据项,数据库系统调用由用户提供的酸洗程序,或者由数据项原生的编程环境的运行时子系统。 要从存储中检索该例程,数据库系统调用由用户或适当的运行时子系统提供的unpickling例程。 由于数据库以其本机格式维护数据项,因此数据项在数据库系统和操作数据项的外部例程之间传递时,不需要转换。 还提供了用于声明可在数据库系统中访问的数据项的属性的技术。 用户提供数据库系统调用的例程,以访问声明的属性,这可能与数据项在其本机环境中具有的实际属性不同。
