Opis

Sometimes we make things more difficult for ourselves than they really need to be. Programmers are no exception to this. For example, those of us of an object-oriented persuasion devote time and expertise to creating a model of a problem domain in terms of objects. We produce solutions that model real-world objects and that are highly extensible and reusable. And then we decide that we need those objects to stick around after the program stops, so we go ahead and create another, totally different model, just so that we can use a database. Our carefully designed objects are then chopped and squeezed to fit this new data model. In fact, most developers would argue that object persistence is a fundamental problem that has yet to be adequately solved. While there are frameworks that hide some of the details of the mismatch between object and data models from the programmer, none of them convi- ingly make what should be a simple job really simple. We held the same opinion, until we found out about db4o. db4o--the database for objects--simply stores native objects. "Native" means that these are the objects that your C# or Java program creates, stored exactly as they are. There's no need to create a database schema, no need to map objects to tables, no need to do anything really, except store objects.

Recenzje

From the reviews:

"The book is a guide to db4o, a tool for building object database management systems. ... This well-designed book covers the programming techniques with Java 1.4 and 1.5 and .NET 1.1 and 2.0; the authors also show that db4o supports both Java and C#. The concepts of object-oriented programming are covered well. ... The position of db4o in the world of relational data is discussed throughout the book. This makes for interesting reading." (S. Balaraman, ACM Computing Reviews, Vol. 49 (2), February, 2008)
