THE DESIGN AND ANALYSIS OF EXPERIMENTS. By Oscar Kempthorne. New York, John Wiley and Sons, Inc., 1952. 631 pp. $8.50. This book by a teacher of statistics (as well as a consultant for \"experimenters\") is a comprehensive study of the philosophical background for the statistical design of experiment. It is necessary to have some facility with algebraic notation and manipulation to be able to use the volume intelligently. The problems are presented from the theoretical point of view, without such practical examples as would be helpful for those not acquainted with mathematics. The mathematical justification for the techniques is given. As a somewhat advanced treatment of the design and analysis of experiments, this volume will be interesting and helpful for many who approach statistics theoretically as well as practically. With emphasis on the \"why,\" and with description given broadly, the author relates the subject matter to the general theory of statistics and to the general problem of experimental inference.

The Object Management Group's (OMG) Model Driven Architecture (MDA) strategy envisages a world where models play a more direct role in software production, being amenable to manipulation and transformation by machine. Model Driven Engineering (MDE) is wider in scope than MDA. MDE combines process and analysis with architecture. This article sets out a framework for model driven engineering, which can be used as a point of reference for activity in this area. It proposes an organisation of the modelling 'space' and how to locate models in that space. It discusses different kinds of mappings between models. It explains why process and architecture are tightly connected. It discusses the importance and nature of tools. It identifies the need for defining families of languages and transformations, and for developing techniques for generating/configuring tools from such definitions. It concludes with a call to align metamodelling with formal language engineering techniques.

Model Driven Engineering

Existing tools for building and deploying complex Web sites are inadequate for dealing with the software production process that involves connecting with underlying logic in a unified and systematic way. As a solution, we propose the OO-H method, an object-oriented software approach that captures relevant properties involved in modeling and implementing Web application interfaces.

Conceptual modeling of device-independent Web applications

This article presents OO-HMethod, an extension of the OO-Method conceptual modelling approach to address the particulars associated with the design of web interfaces. It is based on the OO-Method class diagram, which captures the statics of the system. The design of the interface appearance and the navigation paths are driven by the user navigation requirements. To achieve its goal, OO-HMethod adds several navigation and interface constructs to the OO-Method conceptual model, which define the semantics suitable for capturing the specific functionality of web application interfaces. A new kind of diagram, the 'Navigation Access Diagram' (NAD) is introduced. All the concepts represented in the NAD are stored in a repository, and from there a functional interface is generated in an automated way. One of the main contributions of this paper is not the proposal of yet another method for web modelling but the extension of an existing conceptual modelling approach.

Extending a Conceptual Modelling Approach to Web Application Design

The mostly "creative" authoring process used to develop many Web applications during the last years has already proven unsuccessful to tackle, with its increasing complexity, both in terms of user and technical requirements. This fact has nurtured a mushrooming of proposals, most based on conceptual models, that aim at facilitating the development, maintenance and assessment of Web applications, thus improving the reliability of the Web development process.In this chapter, we will show how traditional software engineering approaches can be extended to deal with the Web idiosyncrasy, taking advantage of proven successful notation and techniques for common tasks, while adding models and constructs needed to capture the nuances of the Web environment. In this context, our proposal, the Object-Oriented Hypermedia (OO-H) Method, developed at University of Alicante, provides a set of new views that extend UML to provide a Web interface model. A code generation process is able to, departing from such diagrams and their associated tagged values, generate a Web interface capable of connecting to underlying business modules.

OO-H Method: extending UML to model web interfaces

Business processes, regarded as heavy-weighted flows of control consisting of activities and transitions, play an increasingly important role in Web applications In order to address these business processes, Web methodologies are evolving to support its definition and integration with the Web specific aspects of content, navigation and presentation

This paper presents the modeling support provided for this kind of processes by the Object-Oriented Hypermedia method (OO-H) and the UML-based Web Engineering (UWE) approach Both methods apply UML use cases and activity diagrams, and supply UML standard modeling extensions Additionally, the connection mechanisms between the navigation and the process specific modeling elements are discussed As a representative example to illustrate our approach we present the requirements, analysis and design models for the wwwamazoncom Website with focus on the checkout process Our approach includes requirements and analysis models shared by OO-H and UWE and provides the basis on which each method applies its particular design notation for business processes

Integration of business processes in web application models

This article presents an extension of the OO-H conceptual modelling approach to address the particulars associated with the design and specification of dynamic personalization. We describe how conventional navigation and presentation diagrams are influenced by personalization properties. The main benefit is that personalization specification can be modified without recompile the rest of the application modules.
