Syntax tree editor for rapid annotation of existing text
Linguistic Tree Constructor (LTC) is a tool for drawing lingusitic syntax trees of already-existing text. It is a syntax editor, not a text editor, so the text has to exist already. It is best suited for large-scale, rapid creation of hand-annotated treebanks. The user can define their own node categories, and can label each node with labels, also definable by the user. LTC supports "generic", X-Bar and RRG trees. Supports interlinear texts in SIL SFM format.

** ATTENTION ** THIS PROJECT HAS MOVED TO: https://github.com/pgmodeler/pgmodeler New releases only will be available on GitHub. PostgreSQL Database Modeler, or simply pgModeler is an open source project of a CASE tool for modeling PostgreSQL that merges the classical concepts of modeling using entity-relationship diagrams with specific features that only PostgreSQL implements. The pgModeler translates the models created by the user to SQL code and apply them onto database clusters from version 8.0 to 9.1. Please, let me know how the pgModeler is working on your computer! Help to improve this project, give your feedback about the software or report any bug at "Tickets" page. Do not forget to detail the bug and if possible attach a screenshot or model database which expressed the bug. Follow the pgModeler profile on Facebook/Twitter and be up-to-date with new features, fixes and releases. https://www.facebook.com/pgmodeler https://twitter.com/pgmodeler
A tool for creating data models and databases for Microsoft SQL Server
Welcome to the page for "Data Modeler"; a free tool to create Microsoft SQL Server databases. If you use Microsoft SQL Server and are in search of a clean and intuitive (and free!) data modeler, search no further. With object-level DDL previews, schema support, real-time model validation and DDL regeneration, sub-models, bulk undo/redo, drag 'n' drop foreign key creation, a data dictionary, update/delete foreign key automation, and customizable fonts and colors, this data modeler is an indispensable tool in any DBAs toolbox. I've used a lot of data modelers, from open-source free software to expensive modelers like Embarcadero ER/Studio. None of them come close for me in terms of ease-of-use and productivity gains. select * from DataModelers where Indispensable='true'; (1 row(s) affected) Google+ https://plus.google.com/+datamodelertool Facebook https://www.facebook.com/DataModelerTool/
