Form Follows Function Model-Driven Engineering for Clinical Trials
Form Follows Function Model-Driven Engineering for Clinical Trials Jim Davies1, Jeremy Gibbons1, Radu Calinescu2, Charles Crichton1, Steve Harris1, and Andrew Tsui1 1 Department of Computer Science, University of Oxford Wolfson Building, Parks Road, Oxford OX1 3QD, UK http://www.cs.ox.ac.uk/firstname.lastname/ 2 Computer Science Research Group, Aston University Aston Triangle, Birmingham B4 7ET, UK http://www-users.aston.ac.uk/~calinerc/ Abstract. We argue that, for certain constrained domains, elaborate model transformation technologies|implemented from scratch in general- purpose programming languages|are unnecessary for model-driven en- gineering; instead, lightweight configuration of commercial off-the-shelf productivity tools suffices. In particular, in the CancerGrid project, we have been developing model-driven techniques for the generation of soft- ware tools to support clinical trials. A domain metamodel captures the community's best practice in trial design. A scientist authors a trial pro- tocol, modelling their trial by instantiating the metamodel; customized software artifacts to support trial execution are generated automati- cally from the scientist's model. The metamodel is expressed as an XML Schema, in such a way that it can be instantiated by completing a form to generate a conformant XML document. The same process works at a second level for trial execution: among the artifacts generated from the protocol are models of the data to be collected, and the clinician conduct- ing the trial instantiates such models in reporting observations|again by completing a form to create a conformant XML document, represent- ing the data gathered during that observation. Simple standard form management tools are all that is needed. -

While the original proposal would be to assist in SQL optimization and tuning at Company A1, the scope of such project would be very time-consuming and require specific expertise within the research team. The scope of the current project was therefore revised, and the new project would consist in determining the current standards and practices in the field of SQL and database optimization in a number of companies represented on the board. Conclusions would be based on a series of interviews with Database Administrators (DBA’s) from the different companies, and on current literature about the topic. The first meeting took place 6th February 2003, and interviews were held mainly throughout the spring Semester 2003. Results would be presented in a final paper, and a presentation would also be held at the end of the project. Individual summaries of the interviews conducted with the DBA’s are included in Part B. A representative set of questions used during the interviews is also included. -

To Appear in the Ninth International Conference on Data Engineering Vienna, Austria April 1993 Data Quality Requirements Analysis and Modeling Richard Y. Wang Henry B. Kon Stuart E. Madnick Sloan School of Management Massachusetts Institute of Technology Cambridge, Mass 02139 [email protected] ABSTRACT Data engineering is the modeling and structuring of data in its design, development and use. An ultimate goal of data engineering is to put quality data in the hands of users. Specifying and ensuring the quality of data, however, is an area in data engineering that has received little attention. In this paper we: (1) establish a set of premises, terms, and definitions for data quality management, and (2) develop a step-by-step methodology for defining and documenting data quality parameters important to users. These quality parameters are used to determine quality indicators, to be tagged to data items, about the data manufacturing process such as data source, creation time, and collection method. -

Chapter 9 – Designing the Database
Systems Analysis and Design in a Changing World, seventh edition 9-1 Chapter 9 – Designing the Database Table of Contents Chapter Overview Learning Objectives Notes on Opening Case and EOC Cases Instructor's Notes (for each section) ◦ Key Terms ◦ Lecture notes ◦ Quick quizzes Classroom Activities Troubleshooting Tips Discussion Questions Chapter Overview Database management systems provide designers, programmers, and end users with sophisticated capabilities to store, retrieve, and manage data. Sharing and managing the vast amounts of data needed by a modern organization would not be possible without a database management system. In Chapter 4, students learned to construct conceptual data models and to develop entity-relationship diagrams (ERDs) for traditional analysis and domain model class diagrams for object-oriented (OO) analysis. To implement an information system, developers must transform a conceptual data model into a more detailed database model and implement that model in a database management system. In the first sections of this chapter students learn about relational database management systems, and how to convert a data model into a relational database schema. The database sections conclude with a discussion of database architectural issues such as single server databases versus distributed databases which are deployed across multiple servers and multiple sites. Many system interfaces are electronic transmissions or paper outputs to external agents. Therefore, system developers need to design and implement integrity controls and security controls to protect the system and its data. This chapter discusses techniques to provide the integrity controls to reduce errors, fraud, and misuse of system components. The last section of the chapter discusses security controls and explains the basic concepts of data protection, digital certificates, and secure transactions. -
