Our aim with this book was to place, under the same roof, two distinct but intertwined aspects of the use of fingerprinting for personal identification and criminal investigation: (1) the aspects associated with the visualization, detection, and recording of friction ridge skin impressions and (2) the issues regarding the identification or individualization of unknown marks when compared with known prints. In 1978, Robert Olsen (1978) published one of the rare books where both aspects were covered with equal weight. Two of us published an overview of fingerprint detection techniques, putting significant emphasis on detection sequences (Margot and Lennard 1994); however, the identification process was only briefly covered. In recent years, we have all been involved in various research projects on fingerprint detection techniques as well as identification issues. We have tried to reflect these dual aspects through our mandate to regularly update the forensic community on the field for the triennial Interpol Forensic Science Symposiums in Lyon (Margot and Lennard 1993; Champod and Margot 1997b, 1998; Meuwly and Margot 2001). We have observed a field that is in rapid progress on both detection and identification issues and, in light of the recent debate on the admissibility of fingerprint evidence in U.S. courts, we have decided to bring together both sides of this discipline within the same volume and to give them the evenhanded critical analysis they deserve.

Any organization that uses the Oracle relational database management system (RDBMS) these days needs to use multiple databases. There are many reasons to use more than a single database in a distributed database system:

• Different databases may be associated with particular business functions, such as manufacturing or human resources.
• Databases may be aligned with geographical boundaries, such as a behemoth database at a headquarters site and smaller databases at regional offices.
• Two different databases may be required to access the same data in different ways, such as an order entry database whose transactions are aggregated and analyzed in a data warehouse.
• A busy Internet commerce site may create multiple copies of the same database to attain horizontal scalability.
• A copy of a production database may be created to serve as a development test bed.

In a distributed database environment, data in two or more databases is accessible as if it were in a single database. Usually, the different databases are on different servers, which may be located at the same site or a continent away. Communication between the servers takes place via SQL*Net (for Oracle7) or Net8 (for Oracle8). Distributed database environments offer a number of benefits over single- database systems, including:

• Tunability
• Platform autonomy
• Fault tolerance
• Scalability
• Location transparency
• Site autonomy

This book describes how you can use multiple databases and the distributed features of Oracle to best advantage. It covers: Table of contents: Part I: The Distributed System

• Introduction to Distributed Database Systems
• SQL*Net and Net8
• Configuration and Administration
• Distributed Database Security
• Designing the Distributed System
• Oracle's Distributed System Implementation
• Sample Configurations 8. Engineering Considerations

Part II: Replication

• Oracle Replication Architecture
• Advanced Replication Option Installation
• Basic Replication
• Multi-Master Replication
• Updateable Snapshots
• Procedural Replication
• Conflict Avoidance and Resolution Techniques

Part III: Appendixes Appendix A: Built-in Packages for Distributed Systems Appendix B: Scripts

Discusses the many tools Oracle provides for designing, developing, administering, and securing distributed database systems. Covers both Oracle8 and Oracle7 syntax, and includes a complete API reference for Oracle's built-in distributed system packages. Softcover. 3 1/2 inch disk included.

The bestselling Java in a Nutshell has been updated to cover Java 1.1. If you're a Java programmer who is migrating to 1.1, this second edition contains everything you need to get up to speed on the new features of Java 1.1. Or if you are just now jumping on the Java bandwagon, Java in a Nutshell still has all of the features that have made it the Java book most often recommended on the Internet. An advanced introduction to Java for C and C++ programmers teaches you everything you need to know about the language, while the complete quick-reference contains descriptions of all of the classes in the Java 1.1 API, with the exception of the Enterprise APIs. Java in a Nutshell also fully describes the syntax of the Java language, making it the only quick reference that a Java programmer needs.

The second edition of Java in a Nutshell covers Version 1.1 of the Java Development Kit (JDK). It includes all of the material from the first edition, as well as the following updated information for Java 1.1:

• A detailed overview of all of the features in Java 1.1, both on a package-by-package basis and in terms of overall functionality.
• A comprehensive tutorial on "inner classes" that explains how to use all of the new types of inner classes: static member classes, member classes, local classes, and anonymous classes.
• Practical, real-world example programs that demonstrate the features in Java 1.1, including object serialization, the new AWT event handling model, internationalization, and a sample Java Bean.
• A complete quick reference for all of the classes, methods, and variables in the core Java 1.1 API. The quick-reference pages include indicators that make it easy to find the 1.1 material. In addition, cross-reference material is now provided directly on each reference page.

With the 1.1 release, Java has grown too large to fit in a single book, even in quick-reference form. Thus, we see the need to splitJava in a Nutshell into multiple volumes. This volume, the "original" Java in a Nutshell, documents the most commonly used features of Java and is an indispensable reference for all Java programmers. We may publish a separate volume that will cover the Java "Enterprise APIs", which include the database connectivity, remote method invocation, and security features, as well as other forthcoming components, such as CORBA IDL support and the electronic commerce framework. And as other new Java APIs are developed and released, we may consider adding new volumes to the Java in a Nutshell series.

One weakness of Java has been its graphics capabilities. Java 1.0 and 1.1 only included simple primitives for line drawing: lines could only be one pixel wide, they could only be solid, and there wasn't any good way to draw curves. Font management and color management were also weak. Java 2D (collectively called the "2D API") signals a major improvement in Java's graphics capabilities. It covers many of the classes in Java 1.2 that address graphics handling and improves on many weaknesses that were present in the previous versions of Java. The 2D API allows you to produce high-quality, professional images on a screen or printer. Java 2D Graphics describes the 2D API from top to bottom, demonstrating how to set line styles and pattern fills as well as more advanced techniques of image processing and font handling. You'll see how to create and manipulate the three types of graphics objects: shapes, text, and images. Other topics include image data storage, color management, font glyphs, and printing. Java 2D Graphics assumes no prior knowledge of graphics. Chock full of detailed explanations and examples, this book provides beginning Java programmers with a solid foundation in 2D graphics and helps more advanced programmers create and use high-quality images in their applications. Topics covered in the book include:

• The rendering pipeline
• Shapes and paths
• Geometry
• Painting with solid colors, gradients, and textures
• Stroking paths, including dashed lines
• Transformations: translation, rotation, shearing, and scaling
• Alpha compositing
• Clipping
• Rasterizing and antialiasing
• Fonts and text
• Font metrics
• Glyphs
• Colors and color spaces
• sRGB and CIEXYZ
• ICC color profiles
• Images, image color models, and image data
• Image processing
• Image data storage
• Graphics devices
• Printing
