New! SimpleORM 3.0 released with the new DataSet architecture
SimpleORM is a full featured Java object relational mapping system that avoids
exotic technologies such as byte code generation.
framework that can use SimpleORM to implement Java web applications
very easily. Simple applications should not be complex to
SimpleORM/Web's extensive use of meta data also enables applications to
be deeply customized by external jars. This enables more
applications to be delivered as core services and separate but deeply
integrated plug in modules.

SimpleORM Version 3.*
SimpleORM provides similar functionality to Hibernate
mapping data in a relational database to Java objects in
Queries can be specified in terms of Java objects, object
identity is aligned with database keys, relationships between objects
are maintained and modified objects are automatically flushed to the
database with optimistic locks.
unlike Hibernate, SimpleORM uses a very simple
object structure and architecture that avoids the need for complex
parsing, byte code processing etc. SimpleORM is small and
transparent, packaged in two jars of just 79K and 52K in size, with
only one small and optional dependency (Slf4j). (Hibernate is
over 2400K plus about 2000K of dependent Jars.) This makes
SimpleORM easy to understand and so greatly reduces technical risk.
SimpleORM version 3.* is a major upgrade that provides a distinct
DataSet component while simplifying record definitions.

No JSPs, no XML at all. There are two styles of usage,
procedure based or a component model. The easiest and quickest
way to build simple web applications.

It provides reusable templates that encapsulate standard user
list, view and update data (CRUD). SimpleWebApp also cut
the layers to integrate interfaces with databases. This means
that the only code you needed to write is real application logic rather
than large quantities of repetitive glue code. And the code
did write is plain old Java code with minimal reflection etc. because

uses JSP technologies to render the templates. Ultimately, it
just became too hard to use JSPs with all their bugs and limitations,
so the move to Simplets.

"SimplestOrm" Is NOT SimpleOrmWe
are annoyed that someone has recently created a project called
"SimplestOrm", which has no relationship to SimpleOrm. It is
fine for people to create new projects, or even to fork SimpleOrm, but
it it is not fine to copy other project's names and thereby cause
confusion. In fact, "SimplestOrm" is everything that
SimpeOrm is not -- it is riddled with reflection and annotations while
being slopy with semantics. We certainly do not endorse it.
Many programmers are clever enough to write clever code, a few programmers are clever enough not to.
XML, no reflection, no annotations. It's simply typesafe java code.
It's easy to use. Because it is open source and the amount of
source code is rather small, there will be always somebody who will
maintain the software. The dataset component is independent
from the jdbc-component. -- Thomas Leichner
