The MIT Libraries provide access to databases and electronic journals via the online catalog and the web. The Vera database was created in order to improve public access to a growing number of resources listed on web pages and also to help the staff more easily maintain these pages. Details of the database, called "Vera" (Virtual Electronic Resource Access), are described, including field definitions and how the database is used by both staff and public. The development of the database helped to improve access and made it easier to maintain a growing number of resources. It has also led to many further questions and discussions among the staff of the MIT Libraries about the scope of the OPAC and how tools like Vera should be related to it. / Co published simultaneously in The Serials Librarian, Vol. 41, no. 3/4, 2002, pp. 227-254; and: E-Serials Cataloging: Access to Continuing and Integrating Resources via the Catalog and the Web, ed. by Jim Cole and Wayne Jones, The Haworth Information Press, 2002, pp. 227-254.

abstract: This thesis addresses the problem of online schema updates where the goal is to be able to update relational database schemas without reducing the database system's availability. Unlike some other work in this area, this thesis presents an approach which is completely client-driven and does not require specialized database management systems (DBMS). Also, unlike other client-driven work, this approach provides support for a richer set of schema updates including vertical split (normalization), horizontal split, vertical and horizontal merge (union), difference and intersection. The update process automatically generates a runtime update client from a mapping between the old the new schemas. The solution has been validated by testing it on a relatively small database of around 300,000 records per table and less than 1 Gb, but with limited memory buffer size of 24 Mb. This thesis presents the study of the overhead of the update process as a function of the transaction rates and the batch size used to copy data from the old to the new schema. It shows that the overhead introduced is minimal for medium size applications and that the update can be achieved with no more than one minute of downtime. / Dissertation/Thesis / M.S.

In establishing the impact of formal data management practices on systems and systems development auditing in the context of a corporate data base environment; the most significant aspects of a data base environment as well as the concept of data management were researched. It was established that organisations need to introduce a data management function to ensure the availability and integrity of data for the organisation. It was further established that an effective data management function can fulfil a key role in ensuring the integrity of the overall data base and as such it becomes an important general control on which the auditor can rely. The audit of information systems in a data base environment requires a more "holistic" audit approach and as a result the auditor has to expand the scope of the systems audit to include an evaluation of the overall data base environment. / Auditing / M.

Image processing systems have typically exhibited a high degree of application specificity. This makes it unlikely that any of the processing tasks for one application can be applied to another. Research has also found that such systems had not made use of knowledge about human perception although, it can be argued, such knowledge is independent of the application. This thesis takes the view that the structures which people perceive in pictures are of considerable importance to supporting picture-based human computer interaction. However, the design of systems which process pictures based on knowledge of human perception presents two major challenges. The first relates to determining the appropriate psychological knowledge that the computational modelling effort will be based upon. The second relates to the testing and evaluation of systems that aim to generate perceptually-valid structures, which poses significant problems because such systems are concerned with perceptual structures rather than semantic interpretations. An approach to developing picture processing systems is proposed that overcomes these problems. The approach represents a development strategy that exploits psychological theory in constructing image processing algorithms. The aim of these algorithms is to generate structures that match those perceived by humans. The approach enables new algorithms to be developed as additional psychological knowledge becomes available. Given appropriate training, users of such systems are able to see in images the structures that are generated by the system. The thesis presents the results of a study of perceptual and computational approaches to the processing of pictures. Motivations for and the development of a computational model based on perceptual grouping are described. A thorough evaluation of the computational model is performed which highlights both its value and limitations. Specific applications of the computational model in areas such as shape emergence in design, and pictorial databases, are then considered.
