内容説明
This book was written for professional database administrators who are considering the implementation of ODBMS products. Loomis provides a no-hype perspective that lays out the pro's and con's, while also debunking myths rampant in the industry. This is a hands-on book for the DBA's, which uses a collection of case studies to offer real world experiences of database administrators who have already implemented O-O databases, what worked and what didn't.
