Dynamically Configurable Distributed Objects - Lewis (2000) (Correct)
....policies for different application requirements. The elements of the DCDO solution are not necessarily unique and fundamentally different from existing techniques to solve related problems. In particular, the model and implementation uses ideas from schema evolution in object oriented databases [6, 7, 8, 19, 22, 54, 55, 56, 62, 63, 64], and from Microsoft s Component Object Model [15, 26, 53] However, these approaches were not designed for distributed object computing systems, which impose different constraints and challenges. High level designs appropriate for this environment have not yet been developed to take advantage of ....

Scaling Access to Heterogeneous Data Sources with DISCO - Tomasic, Raschid, Valduriez (1998) (33 citations) (Correct)
....interface. This statement also creates an object in the MetaExtent type, to be described later. Thus, each Disco extent represents a collection of data in one data source, of some particular type. A more general approach associates an implementation for a mediator type with each data source [36] [50]) The wrapper extent name p0 is used by the wrapper to access data. For a relational database, it will be the relation name. The mediator checks that the mediator type Person is indeed exported by the data source. If the wrapper cannot match (or convert) the type in the mediator to the type in ....

Scaling Heterogeneous Databases and the Design of DISCO - Tomasic, Raschid, Valduriez (1996) (106 citations) (Correct)
....handle the case where there is a mismatch of types, and this is discussed in section 2.2.2. Thus, each Disco extent represents a collection of data in one data source. This intuition is the key to the Disco data model. A more general approach associates an implementation with each data source [5, 27]) At this point, data access from the data source is possible. The following query: select x.name from x in person0 where x.salary 10 returns the answer Bag( Mary ) with respect to the data source defined in the introduction. Several conditions must hold for this answer to be returned. The name ....

Exploiting Structured Data in Wide-Area Information Systems - John Ockerbloom (1995) (1 citation) (Correct)
....such an agent for abstract type services. Rufus creates structured abstract objects as proxies for unstructured data files that encode the abstract objects. The expert agent, known as a classifier , analyzes the file contents to select a type to use for constructing the object. The paper [SS94] describes an algorithm that allows the classifier to learn to classify an arbitrary number of new types. Rufus is designed for a single site, and in its current form does not scale up to Internet wide information systems. Extendable types: Most distributed object systems allow an unlimited ....
