A comprehensive, community-maintained collection of design pattern implementations in Java, offering well-documented, educational examples to help developers understand and apply common architectural solutions. All designs should be as simple as possible. You should start with KISS, YAGNI, and Do The Simplest Thing That Could Possibly Work principles. Complexity and patterns should only be introduced when they are needed for practical extensibility. The design patterns are now available as an e-book. Design patterns can speed up the development process by providing tested, proven development paradigms.

BIRT is an open source technology platform used to create data visualizations and reports that can be embedded into rich client and web applications. Developers who use BIRT Designer are able to access information from multiple data sources easily and quickly in order to create reports and applications with stunning data visualizations. Actuate now provides a free report server, BIRT iHub F-Type, to deploy BIRT content so developers don't have to build their own infrastructure. With a flexible Open Data Access framework, developers can write custom data drivers to access data from any source, including Big Data sources like Apache Hadoop, Cassandra, and MongoDB, along with all traditional relational databases, Flat Files, XML data streams, and data stored in proprietary systems. Built for embedding, BIRT includes APIs for data access, chart generation, output formats, content execution, and integration within larger applications.

Design/Reverse Engineer/Generate Scripts/Compare Versions of all major databases with "Apricot DB" ERD- tool "Apricot DB" is a database tool for design and analysis of the relational database structure. It represents the DB- structure in the form of editable Entity/Relationship Diagrams (ERD). "Apricot DB" allows to perform reverse engineering on the existing database, as well as to create a new database structure from scratch. Allows to generate the essential DDL- scripts for CREATE/DROP/DELETE- operations based on the current ERD. "Apricot DB" supports two popular ERD notations: the "Crow's Foot" and "IDEF1x". The databases supported by Apricot DB: Oracle; SQL Server; MySQL; MariaDB; PostgreSQL; DB2/DB2 LUW; H2; SQLite Your feedback is appreciated.

Green, an Eclipse plugin, is an advanced yet simple UML class-diagram tool, developed primarily for student use. It does live round-tripping, so it's easy to move between diagram and code views. It's extensible: users can define their own relations

Fourth generation database designer and code-generator for educational purposes and speeding-up database designing and creating work.

An integrated CASE system that: • Supports multiple views and stages of project development – from keeping track of reference documentation to analysis/design modelling, to project implementation, roll-out and tracking the project-related issues. • Supports distributed development of projects by multiple participants, while proactively enforcing access control rules and auditing changes. • Is available on all platforms where development takes place (Windows, Unix/Linux, MacOS, Solaris, etc.) • Offers ideological and conceptual integrity across all facilities. By adapting a new approach to CASE tool architecture (integration at repository level and developing a component-based CASE system instead of a monolithic tool) an entirely new species of tools can be brought into a useful existence – an integrated environment where all project-related activities can be performed efficiently.

WireMaster is a user interface (UI) tool for creating wireframes in an open, XML based format. A wireframe is a basic visual guide used in web design to suggest the structure of a website and relationships between it's pages.

ConceptBase.cc is a multi-user deductive and object-oriented database system for metamodeling and method engineering. Includes a graphical client that builds upon the logic-based features of the ConceptBase.cc server. The data model is O-Telos. ConceptBase.cc can represent information at the data level (example data, traces of process executions etc.), the class level (schemas, process definitions etc.), the metaclass level (constructs of modeling languages), the meta-metaclass level (constructs for defining modeling languages), and so forth. ConceptBase.cc is developed by the ConceptBase Team at University of Skövde (HIS). ConceptBase.cc supports Linux, Mac OS X and Windows. ConceptBase.cc is free software distributed under a FreeBSD-style license.

Support for more productive Model Based Systems Engineering, following the recommendations in the Cookbook of the INCOSE SE2 Challenge team http://mbse.gfse.de The Plugin for the MagicDraw modelling tool provides support for model based document generation which ties together system model and documents to keep them up to date and consistent, using a AWYSIWYG editor in MagicDraw. It provides basic support to model variants and extract variants from a system model. It provides support to generate organizational structures according to the SE2 Cookbook recommendations. It provides basic pattern based support to reason on a system model, for example to extract numbers like total power, cost, power consumption for a given product tree The MBSE plugin for MagicDraw requires MagicDraw 17.0 SP4 or higher with an installed SysML plugin 17.0 SP5 or higher. Installation instructions can be found in the file ReadMe.txt in the download area as well as the corresponding UMs.
