Using and Understanding Java Data Objects
JAVA DATA OBJECfS (JDO) specifies a transparent persistence service for Java objects. The specification describes a general framework for storing and retrieving the per sistent state ofJava objects. The JSR-12 expert group defined JDO using the Java Community Process. JDO includes a specification, a reference implementation, and a technology compatibility kit (TCK). All three can be downloaded from the JavaCommunityProcessWebsite (http://W~M.jcp.org/jsr/detail/12.jsp). Anumber of vendors have created implementations of JDO and provide versions of their products that you can download from the Web. URLs to some of these vendors are found near the end of this introduction. Java programmers use tools to make their projects successful. Most applications and server-side components involve moving data between objects in memory and persistent storage. JDO promises to change the way that Java programmers store and retrieve object state. JDO simplifies the application's code, increases the appli cation's portability, and helps to separate concerns in the application's design. Compared to existing alternatives, JDO makes persistence easier to understand, easier to model, and easier to code. Who Should Read This Book This book is intended for Java programmers and application architects. It assumes that you know how to program in Java, and it assumes that you want to use JDO and understand how it works. This book emphasizes what you need to know to use JDO effectively.
Java Persistence for Relational Databases
Java Persistence for Relational Databases is chock full of best practices and patterns, for those of you who want to connect to databases using Java! Coverage includes various database-related APIs for Java, like JDO, JDBC (including the newest 3.0 APIs), and CMP (“Container Managed Persistence” with EJB). All those things you developers have wanted to know—but were afraid to ask—are featured inside this book. It offers a realistic and multi-angled look at persisting Java objects. Whether your environment requires you to use JDO, CMP, Castor, or to hand-code a persistence layer using JDBC, the answers all lie inside this book.
Objects, Abstraction, Data Structures and Design Using Java Version 5.0
This version of the book uses the latest Java technology, Java 2 Standard Edition Version 5.0 (J2SE V. 5.0), or otherwise known as "Version 5.0." This revolutionary book intertwines problem solving and software engineering with the study of traditional data structures topics. The book emphasizes the use of objects and object-oriented design. Early chapters provide background coverage of software engineering. Then, in the chapters on data structures, these principles are applied. The authors encourage use of a five-step process for the solution of case studies: problem specification, analysis, design, implementation, and testing. As is done in industry, these steps are sometimes performed in an iterative fashion rather than in strict sequence. The Java Application Programming Interface (API) is used throughout the text. Wherever possible, the specification and interface for a data structure follow the Java Collections Framework.
