- Patterns of persistence, Part 1: Strategies and best practices for modern ORM tools by Ryan Senior, Travis Klotz, Jim Majure - [Clicks: 129]
Although many developers use object-relational mapping (ORM) tools for their applications' persistence tier, some are confused about how to use them and duplicate code unnecessarily. The authors' experience constructing many persistence tiers has given them a clear understanding of persistence patterns and best practices. The first part of this two-part article covers the basics of a consistent, concise domain model and persistence tier. Part 2 builds and expands on the concepts covered in this article.

Part 1 of this two-part article covers the basics of achieving a consistent, concise domain model and persistence tier with modern object-relational mapping (ORM) tools. In Part 2, the authors describe base domain entities, behavior in the domain model, and more-advanced features of a generic DAO. They also share strategies for enhancing data-retrieval performance with the domain model.
