Transparent persistence in object-relational mapping
In object-relational mapping products, the
ability to directly manipulate data stored in a relational database using an object programming
language is called transparent persistence.
This is in contrast to a database sub-language used by embedded SQL or a call
interface used by ODBC or JDBC. See transparent
persistence vs. JDBC call-level interface (new window).
Using an object-relational mapping product means
you will have less code to write and, depending on how you use your data, you might have higher
performance over an embedded SQL or a call interface. See caching
for object-relational mapping (new window).
With transparent persistence, the manipulation
and traversal of persistent objects is performed directly by the object
programming language in the same manner as in-memory, non-persistent objects.
This is achieved through the use of intelligent caching as this animation shows.
For coding examples, see how
to access data in a relational database.

Foundation for Object / Relational Databases: The Third Manifesto by C. J. Date, Hugh Darwen Average Customer Review: based on 4 reviews. Customer Review: Mr. Data and Mr. Darwen have much to say in this book. The question is will community of "database" people read it, assimilate it, and get to sufficient mass to discuss the merits of the concepts described in this book? And, if that does happen, will it be too late to implement any of the concepts in a real DBMS? There is no question...

Customer Review: Al Stevens, C++ Database Development (MIS Press, 1992) Two questions come to mind as to why anyone would be reading a ten-year-old book on database development in an outdated edition written to cater to an operating system that (almost) no longer exists in any meaningful way. (Or why they would be reading a review of such a book.) Tho...
