Uncle Unc is a framework for working with trees of objects. Existing services such as filesystems, code libraries, networks, log files, mailboxes and directories can be mapped onto this object tree, as can some traditional desktop applications. User interfaces work directly with the object tree, offering best of breed interface design (e.g. filtering, breadcrumb bars, paging, sorting, and file-explorer-like views) across the full range of services. The framework promotes clean design, completeness of representation, and reusability of both front end and back end code.
MaVerick is a MultiValue database management system. MultiValue databases are said to be one of the computer industry's best kept secrets. First appearing over 30 years ago as PICK, they have continued to evolve through various commercial vendors, and are still in active development today. They are very resource friendly, are incredibly fast, feature a very user friendly data retrieval and reporting language (variously called ACCESS or English), and a rapid application development language based originally on Dartmouth Basic. The MaVerick project is an attempt to create an open source variant, written in Java.
Apache Cayenne is a persistence framework that provides object-relational mapping (ORM) and remoting services. It has a wealth of unique and powerful features and can address a wide range of persistence needs. Cayenne seamlessly binds one or more database schemas directly to Java objects, managing atomic commit and rollbacks, SQL generation, joins, sequences, and more. With Cayenne's Remote Object Persistence, those Java objects can even be persisted out to clients via Web Services. With native XML serialization, objects can be even further persisted to non-Java clients.
