 title:  About Cayenne

-Explore  the following pages to learn more about what Cayenne is and how it
-can help your project.
+Cayenne is a Java _object relational mapping (ORM) framework_.  In other
+words, it is a tool for Java developers who need to talk to a database (or
+many databases).  Rather than hardcoding SQL statements through Java code,
+Cayenne allows a programmer to work only with Java objects abstracted from
+the database.  Here are just a few benefits of the Cayenne approach to
+persistence:
 
-* [Why Cayenne?](why-cayenne?.html)
-* [Download](download.html)
-* [Success Stories](success-stories.html)
-* [Commercial Support](commercial-support.html)
+* Portability between almost any [database](/database-support.html)
+ that has a JDBC driver without changing a single line of code in your
+application.
+* No knowledge of SQL is required (while it still can be helpful).
+* Code which validates any data committed to the database is easy to write
+and foolproof in operation.  This might be as simple as ensuring passwords
+have enough characters, or a complex check on the validity of a set of
+accounting operations in a general ledger transaction.  This allows you to
+move common error checking code out of the GUI layer and provides valuable
+protection against programming mistakes.
+* Caching in order to make your application faster and avoid repeated hits
+on the database for the same data.
+* Automatic faulting (lazy loading) of relationships, but easily supports
+prefetching of related data for improved performance when needed.
+* Pagination which reduces bandwidth and query times by only loading the
+contents of objects when they are actually needed.  The classic example of
+paging, which differs from faulting, is when a query returns 97 records,
+and you want to display 10 at-a-time to the user.  With paging, only the
+first 10 records are fully loaded.  Cayenne will automatically load only
+the page of records as they are requested.
+* Configurable optimistic locking to ensure data integrity and prevent
+unexpected data issues when another tool has changed the database behind
+the scenes (such as a maintainer updating a record in the database while a
+Cayenne-based application had the same record loaded to make changes).
+* A GUI-based database/schema modeler to simplify learning Cayenne.  The
+modeler saves to XML-based files, which can be hand-edited if needed.
+
+Also here are a few things that set Cayenne apart from other ORM products:
+
+* Cayenne can also work in three tier (ROP) mode where multiple clients
+connect to the data source not via JDBC but through a remote Cayenne
+controlled service.  This gives much greater control over centralized
+validation, caching and a seamless persistence of objects from the server
+through to the clients.  The clients might themselves be web servers
+delivering a distributed load balancing web farm or a rich GUI client such
+as a desktop Swing/SWT application.
+
+* A persistent object doesn't have to be of a class known at compile time.
+Instead Cayenne can use a generic class with mapping defined dynamically in
+runtime (all without any bytecode manipulation).
+
+* Cayenne supports "nested contexts" allowing an arbitrary number of
+nesting levels for commit/rollback operations. This way a user can create
+"scratch contexts" for working with objects, with the ability to discard
+(or save) those changes without affecting an overall larger set of
+uncommitted changes.

-title:  Why Cayenne
-permalink: /why-cayenne/
----
-
-Cayenne is a Java _object relational mapping (ORM) framework_.	In other
-words, it is a tool for Java developers who need to talk to a database (or
-many databases).  Rather than hardcoding SQL statements through Java code,
-Cayenne allows a programmer to work only with Java objects abstracted from
-the database.  Here are just a few benefits of the Cayenne approach to
-persistence:
-
-* Portability between almost any [database](/database-support.html)
- that has a JDBC driver without changing a single line of code in your
-application.
-* No knowledge of SQL is required (while it still can be helpful).
-* Code which validates any data committed to the database is easy to write
-and foolproof in operation.  This might be as simple as ensuring passwords
-have enough characters, or a complex check on the validity of a set of
-accounting operations in a general ledger transaction.	This allows you to
-move common error checking code out of the GUI layer and provides valuable
-protection against programming mistakes.
-* Caching in order to make your application faster and avoid repeated hits
-on the database for the same data.
-* Automatic faulting (lazy loading) of relationships, but easily supports
-prefetching of related data for improved performance when needed.
-* Pagination which reduces bandwidth and query times by only loading the
-contents of objects when they are actually needed.  The classic example of
-paging, which differs from faulting, is when a query returns 97 records,
-and you want to display 10 at-a-time to the user.  With paging, only the
-first 10 records are fully loaded.  Cayenne will automatically load only
-the page of records as they are requested.
-* Configurable optimistic locking to ensure data integrity and prevent
-unexpected data issues when another tool has changed the database behind
-the scenes (such as a maintainer updating a record in the database while a
-Cayenne-based application had the same record loaded to make changes).
-* A GUI-based database/schema modeler to simplify learning Cayenne.  The
-modeler saves to XML-based files, which can be hand-edited if needed.
-
-Also here are a few things that set Cayenne apart from other ORM products:
-
-* Cayenne can also work in three tier (ROP) mode where multiple clients
-connect to the data source not via JDBC but through a remote Cayenne
-controlled service.  This gives much greater control over centralized
-validation, caching and a seamless persistence of objects from the server
-through to the clients.  The clients might themselves be web servers
-delivering a distributed load balancing web farm or a rich GUI client such
-as a desktop Swing/SWT application.
-
-* A persistent object doesn't have to be of a class known at compile time.
-Instead Cayenne can use a generic class with mapping defined dynamically in
-runtime (all without any bytecode manipulation).
-
-* Cayenne supports "nested contexts" allowing an arbitrary number of
-nesting levels for commit/rollback operations. This way a user can create
-"scratch contexts" for working with objects, with the ability to discard
-(or save) those changes without affecting an overall larger set of
-uncommitted changes.
