摘要： An object type translator (OTT) determines one or more database object types. The one or more database object types are mapped to a first structural language type definition code. After being generated, the user may add user code to the first structural language type definition code. During regeneration of these files, the first structural language type definition code is then parsed to determine the user code that has been added, based on the start and end markers that the user code segments have been marked with. OTT maps these user-code segments to the corresponding database types and keeps track of the mapping and the user code. When the OTT starts generating the second structural language code, the OTT determines a position where the user code should be inserted into the second structural language type definition code using that mapping. The user code is then inserted in the second structural language code in the position determined. Accordingly, the user code that was added is not lost when the structural language type definition code is regenerated from the one or more database object types.

摘要： A method for providing memory management for objects is described. Specifically, techniques are described for providing common memory management code to objects that are instances of different classes and for releasing a memory management subtree that starts with a particular object in the memory management tree. A memory management template provides common pre-processor memory management code. A specialized version of the memory management template is used to create a specialized template subclass. When a memory management operator of an object that is an instance of the specialized template subclass is invoked the common memory management code in the specialized template is executed. Memory is associated with each object in a hierarchical tree. Data for the memory is maintained that reflects the hierarchical tree relationship between the objects. A subtree and the associated memory can be released without an application program tracking the relationships.

摘要： Schema conversion approaches convert images of complex objects. The schema conversion is performed on images of complex objects belonging to a root class, whether those objects are instances of the root class or instances of a subclass of the root class. A complex object is an object that is comprised of a collection of objects or that has another object as an attribute. The approaches use change vectors to represent changes to make to an image to convert it between the target schema version and source schema version. Change vectors are generated based on schema version records, each of which describes the properties of a schema version, including the attributes in the schema version and the data type of each of the attributes. The approaches evolve changes that includes addition, modification and deletion of object attributes. They convert from an earlier schema version to a later schema version, and vice versa, i.e. from a later schema version to a earlier schema version.

摘要翻译： 模式转换方法转换复杂对象的图像。 对属于根类的复杂对象的映像执行模式转换，无论这些对象是根类的实例还是根类的子类的实例。 复杂对象是由对象集合或具有另一对象作为属性组成的对象。 这些方法使用变化向量来表示对图像进行的更改，以在目标模式版本和源模式版本之间进行转换。 基于模式版本记录生成更改向量，每个模式描述模式版本的属性，包括模式版本中的属性和每个属性的数据类型。 这些方法演变了包括对象属性的添加，修改和删除的更改。 它们将从较早的模式版本转换为较后的模式版本，反之亦然，即从较后的模式版本转换为较早的模式版本。

摘要： One embodiment of the present invention provides a system that facilitates transactional consistency for references in an object-relational database. The system operates by first receiving a reference to an object located in the object-relational database. Next, the system creates a reference object within local storage that includes an object descriptor to indicate whether the object has been loaded into local storage. The reference is stored in this reference object. A pointer within an application program can then point to the reference object, so that the application program can use the pointer to access the object.

摘要： An improved method, mechanism, and system for implementing, generating, and maintaining for implementing session pools is disclosed. A session in a session pool can be customized to with a specific set of affinities and attributes. Tags can be associated with the customized sessions. When a later request is made for a session having a set of desired characteristics, the tags can be used to search for and identify a session in the session pool having the requested characteristics. Also disclosed is a method, mechanism, and system for dynamic sizing of session pools.
