Today's database management systems implement sophisticated access control mechanisms to prevent unauthorized access and modifications. For instance, this is an important basic requirement for SOX (Sarbanes‐Oxley Act) compliance, whereby every past transaction has to be traceable at any time. However, malicious database administrators may still be able to bypass the security mechanisms in order to make hidden modifications to the database. This paper aims to address these issues.

In this paper the authors define a novel signature of a B⁺‐tree, a widely‐used storage structure in database management systems, and propose its utilization for supporting the logging in databases. This additional logging mechanism is especially useful in conjunction with forensic techniques that directly target the underlying tree‐structure of an index. Several techniques for applying this signature in the context of digital forensics on B⁺‐trees are proposed in the course of this paper. Furthermore, the authors' signature can be used to generate exact copies of an index for backup purposes, thereby enabling the owner to completely restore data, even on the structural level.

For database systems in enterprise environments, compliance to regulatory standards such as SOX (Sarbanes‐Oxley Act), whereby every past transaction has to be traceable at any time, is a fundamental requirement. Today's database management systems usually implement sophisticated access control mechanisms to prevent unauthorized access and modifications. Nonetheless malicious database administrators would be able to bypass the security mechanisms in order to make modifications to the database, while covering their tracks.

In this paper, the authors demonstrate how the tree structure of the underlying store engine can be used to enhance forensic logging mechanisms of the database. They define a novel signature for B⁺‐trees, which are used by the InnoDB storage engine. This signature stores the structure of database storage files and can help in reconstructing previous versions of the file for forensic purposes. Furthermore, the authors' signature can be used to generate exact copies of an index for backup purposes, thus enabling the owner to completely restore data, even on the structural level. The authors applied their concept to four real‐life scenarios in order to evaluate its effectiveness.

To report the highlights of the annual Library and Information Technology Association (LITA) Top Technology Trends program at 2007 American Library Association Annual Conference in Washington, DC.

Provides a brief review of the conference program on technology issues in libraries.

This summary of LITA section Top Technology Trends program with presentations and information. The presentations focus is on new technologies and their applications in a variety of library environments. The program offered a wide variety of timely presentations that were on new and emerging technologies and the application to the library environment.

Provides descriptions of opinions on technological trends in library and information services from industry professionals.

BRS Five databases on BRS are now updated weekly: Medline, the Institute for Scientific Information's Arts and Humanities Search and Social SciSearch, and Information Access Company's Magazine ASAP III and Magazine Index. With this enhancement, subscribers to BRS's Selective Dissemination of Information (SDI) can get updates more often. SDI lets users enter a specific search strategy in a particular database. Each time the database is updated any new references are automatically mailed to the subscriber.

Focuses on the year 2000, reviewing the periodical literature of information and library services management, and of the relevant literature from the field of management in general. Notes the themes of major conferences in the field of information and library services management, and of reference tools for library managers.
