Praise for Core JAVA Data objects "Core JDO is packed with valuable information and provides a strong foundation for building JDO-based Enterprise applications." ” Dan Malks, Author, Core J2EE Patterns "All Java developers working on business applications should understand the implications of JDO. This book helps them to do just that." ” Scott W. Ambler, Author, Agile Database Techniques "Core JDO is a must read book for those interested in Java Data Objects.The authors provide a solid introduction to the JDO standard but then focus on how to use JDO in the real world, reflecting their experiences as members of the spec team as well as application developers." ” Neelan Choksi, President, SolarMetric "Core JDO probes the innards of JDO and explains everything lucidly, from the fundamentals to its most advanced features (using JDO with EJB, JCA, Security, Transactions, etc). The book stands out as an excellent JDO resource for both Architects and Developers alike. Congratulations and thanks to the Authors, Sun, and Prentice-Hall for bringing out such a great book on JDO." ” Gopalan Suresh Raj, Chief Architect, hywy Software Corporation "Core JDO is a clear and detailed treatment of JDO. The JDO and EJB chapter is essential reading for anyone involved in Enterprise Java development." ” David Tinker, Hemisphere Technologies "The Core JDO Book provides the reader exceptional in-depth information about JDO. What I like in particular is that the book doesn't stop by just explaining the technology in a vaccuum. It provides plentiful guidance how to use it in real world application environments such as J2EE, it includes a very helpful comparison with JDBC and helps the reader to make a more informed decision on his application database architecture, and almost all topics are accompanied with extensive code examples that help learning JDO the easy way." ” Dirk Bartels, General Manager, JDOcentral.com "When JBoss Group looked at the available APIs for orthogonal persistence, JDO emerged as a finally mature standard. It was clear we needed to implement JDO in JBoss. This book is very well written, with a balanced mix between specification coverage and practical tidbits. A must read." ” Marc Fleury, President and Founder, JBoss Group, LLC. "As a JDO vendor we are very keen on this book.This is a book that Java architects and programmers can use to save weeks when they want to build and deploy critical J2EE transactional applications." ” Eric Samson, President, LIBeLIS  |
