Updating XML data is very wide area, which must solve a number of difficult problems. From designing language with sufficient expressive power to the XML data repository able to apply the changes. Ways to deal with them are few. From this perspective, is this work very closely dedicated only to the language XQuery. Thus, its extension for updates, for which the candidate recommendation by the W3C were published only recently. Another specialization of this work is to focus only on the XML data stored in the object­relational database with that repository will enforce the validity of documents to the scheme described in XML Schema. This requirement, combined with the possibility of updating of data in the repository is on the contradictory requirements. In this thesis is designed language based on XQuery language, designed and implemented evaluating of the update queries of the language on the store and a description and implementation of the store in object­relational database.

Investigou-se neste trabalho a proposta de um Modelo Lógico Gráfico para suporte à fase do Projeto Lógico em BDORs. O Modelo Lógico Gráfico proposto é uma extensão da UML para o Diagrama de Classes. A extensão deu-se por meio da elaboração de um Perfil UML, o qual foi disponibilizado em XMI para ser empregado em ferramentas CASE de diferentes fabricantes. Desenvolveu-se dois módulos para a ferramenta CASE ArgoUML. Esses módulos têm por finalidade a automação do desenvolvimento em BDORs, onde, a partir de um esquema gráfico, projetado utilizando-se o Modelo Lógico Gráfico proposto, gera-se código no padrão da SQL:2003 e no dialeto SQL utilizado pelo Oracle 11g. Foi proposta uma arquitetura baseada na ANSI/SPARC e na MDA para o projeto em BDORs que relaciona as fases do Projeto com as tecnologias empregadas para suportá-las. Por meio dessa arquitetura, destacam-se os pontos onde houve contribuição deste trabalho e os pontos que serão alvos de futuras pesquisas. Esta dissertação difunde os recursos existentes em BDORs e facilita a elaboração do Projeto Lógico em BDORs ao disponibilizar o modelo gráfico proposto e ao automatizar seu desenvolvimento na ferramenta CASE ArgoUML. / A Logical Graphic Model was proposed to support the Logical Design phase in ORDB. The Logical Graphic Model proposed is an extension of the UML Class Diagram. The extension was obtained by the elaboration of a UML Profile, which was released in XMI to be used in CASE tools from different manufacturers. Two modules were developed for ArgoUML CASE tool. These modules were designed to automate the development in ORDB, where, from a logical graphic, projected using the proposed Logical Graphic Model, creates the code standard SQL: 2003 and the SQL dialect used by Oracle 11g. An architecture based on the ANSI / SPARC and MDA for the project in ORDBs was proposed. This architecture associates the Project phases with the technologies used to support them. Through this architecture, the contributions of this paper and the subjects that will be target for future researches are highlighted. This dissertation diffuses the existing resources in ORDBs and facilitates the development of the Logical Design in ORDB, by disposing the proposed graphic model and automating its development in the ArgoUML CASE tool.

本研究以使用者需求導向為設計原則，提出了建構物件與物件關聯資料庫工作量產生器的發展方式，以解決(1)一般績效評估標準規格因只針對特定應用領域，而無法周詳考慮到使用者的特定需求問題；(2)廠商所發展的工作量產生器則因為可能針對其產品的特定領域作設計與測試，而失去了公正性之問題。我們的目地就是希望能以此資料庫工作量產生器的設計方式使測試資料庫效能的工作量，對使用者而言更具一致性、代表性與正確性，如此測試之結果對使用者而言才能更具意義。 我們首先分析SQL3與ODMG標準，以此構成物件關聯與物件導向資料庫之一般化的工作量模式。然後，再著手以使用者需求導向為原則，設計工作量產生器的運作方式。最後，我們實際發展了工作量產生器的雛形系統，以讓使用者能真正依其需求建立工作量並實際作績效測試，並提供給欲建構物件與物件關聯資料庫工作量產生器的人員作參考。 / This thesis provides a method of establishing Object-Oriented and Object-Relational Database Workload Generator, and this method is designed from the perspective of the user's requirements for addressing two problems: (1) the benchmark standards are generally designed to specific domains, so they are unable think comprehensively users' special requirements. (2) the database workload generators that developed by database providers may lose justice, because they might be designed to their products' special domain. Our purpose is that hope this method can make the Workload more consistent, more representative and more accurate and the test result will be more meaningful to users. Firstly, we analyze the SQL3 and ODMG standards to compose the ORDBs' and OODBs' generalized Workload Models. Then, we design our Workload Generator form the perspective of the user's requirements. Finally, we develop the Workload Generator's prototype system, it can allow users to create Workload according to their actual requirements and really do the benchmark test, and furthermore can provide a reference resource to the people who want to develop ORDB and OODB Workload Generator.
