The first, termed vertical, analyzes the semantics of the application and distributes it across multiple nodes based on its community of users and how they access the system. The second, termed horizontal, declusters the application's data across multiple nodes with the objective to distribute client requests evenly across these nodes. Hybrid, our third approach, considers a horizontal partitioning of services identified by a vertical partitioning. The paper describes the application of each approach to newsblaster.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.

Traditional version control methods, such as RCS, use edit scripts representing changes in the document to support the incremental reconstruction of different versions. The edit-based approaches have been enhanced with a replication scheme called UBCC (Chien et al., 2000). UBCC is based on the notion of page usefulness and ensures effective management for multi-version documents in terms of both retrieval and storage cost. These improvements notwithstanding, the edit-based representation suffers from limited generality and flexibility-e.g., it cannot represent changes such as rearranging the document or duplicating parts of its content. To solve these problems, the paper proposes a copy-based UBCC versioning scheme, which also provides a simpler format for the electronic exchange of multi-version documents. With the objective of matching the performance of the edit-based UBCC technique, we develop algorithms that enhance the copy-based UBCC scheme with page usefulness management. We also present results of various experiments that test the storage and retrieval performance of the new copy-based approach, and compare it with that of the edit-based UBCC approach.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.

In many applications, specific document type definitions (DTDs) are designed to enforce a semantically agreed-upon structure of the XML documents for management. However, both the data and the structure of XML documents tend to change over time for a multitude of reasons, including to correct design errors in the DTD, to allow expansion of the application scope over time, or to account for the merging of several businesses into one. However most of the current software tools that enable the use of XML do not provide explicit support for such data or schema changes. In this vein, we put forth the first solution framework, called XML Evolution Manager (XEM) to manage the evolution of XML. XEM provides a minimal yet complete taxonomy of basic change primitives. These primitives, classified as either data changes or schema changes, are consistency-preserving, i.e., for a data change, they ensure that the modified XML document conforms to its DTD both in structure and constraints; and for a schema change, they ensure that the new DTD is a valid DTD and all existing XML documents are transformed also to conform to the modified DTD. We prove the completeness of the taxonomy in terms of DTD transformation. To verify the feasibility of our XEM approach we have implemented a working prototype system using PSE Pro as our backend storage system.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.

In such systems, users subscribe to the dissemination service by providing interest profiles. These profiles are then used to determine which information should be delivered to which users, whenever new information is entered into the system. A main shortcoming of existing dissemination systems is the lack of any access control mechanisms, enabling selective information dissemination based for example on security or other regulatory policies. We present an access control model suitable for dissemination systems. The model is based on user profiles containing both user interests and user credentials (i.e., a set of attributes characterizing users for access control purposes). Information is then filtered before being delivered to users on the basis of both the user interests and credentials. To make authorization manageable when dealing with very large information systems, our model supports authorization domains, that allow one to group together information objects to which the same access control policies apply. Finally, in addition to formally defining our model and developing the related access control algorithm, we outline an implementation strategy.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.

Current archival approaches build upon standardized data formats and simple metadata mechanisms for collection management, but do not involve high-level conceptual models and knowledge representations. This results in serious limitations, not only for expressing various kinds of information and knowledge about the archived data, but also for creating infrastructure independent, self-validating and self-instantiating archives. To overcome these limitations, we first propose a scalable XML-based archival infrastructure, based on standard tools, and subsequently show how this architecture can be extended to a model-based framework, where higher-level knowledge representations become an integral part of the archive and the ingestion/migration processes. This allows us to maximize infrastructure independence by archiving generic, executable specifications of: archival constraints (i.e., model validators); and archival transformations that are part of the ingestion process. The proposed architecture facilitates construction of self-validating and self-instantiating knowledge-based archives. We illustrate our overall approach and report on first experiences using a sample collection from a collaboration with the National Archives and Records Administration (NARA).","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.

In such a system, once the XML data is dissembled and loaded into the storage system, XML queries posed against the (virtual) XML documents are processed by translating them into SQL queries against the relational storage. However, for applications which frequently update their XML documents, we cannot afford to reload a complete, possibly large, document for each update, instead we must be able to incrementally propagate document updates to the stored XML data. We address the issue of correctly reflecting updates of external XML documents into the loaded XML data in a relational database system. We describe Clock, a framework for synchronizing the relational storage with updated XML documents by exploiting a metadata-driven technology. First, we propose a set of (DTD preserving) update primitives for XML documents. Second, based on the mapping between XML and the relational model, we describe the propagation of those update primitives. Validation of the updates ensures they will not violate the constraints specified by the DTD. We have implemented a working prototype of the Clock system using the IBM's XML4J parser JDBC 2 and Oracle 81. We report on preliminary experiments conducted using this prototype to analyze our algorithms in a document update setting.","PeriodicalId":368473,"journal":{"name":"Proceedings Eleventh International Workshop on Research Issues in Data Engineering.
