pgintcl is a pure Tcl interface to the PostgreSQL database system. It provides an alternative to pgtcl and pgtcl-ng but does not require a compiled Tcl extension (libpgtcl) or PostgreSQL client library (libpq). This allows developers to create Tcl utilities and applications that are platform neutral. Trade-offs are slower performance and PostgreSQL protocol version dependency.
SQLScreens is a simple relational database screen form generator written in TCL/TK. It will let you create query screens very quickly by specifying what data (tables and columns) you want to see and what operations should be allowed (query/update, etc.). It will take care of creating the user interface and the behind-the-scenes SQL. SQLScreens can be used with different backend database systems, and includes direct support for MySQL, SQLite, and INFORMIX, and ODBC for others.
Berkeley DB (libdb) is a programmatic toolkit that provides embedded database support for both traditional and client/server applications. It includes b+tree, queue, extended linear hashing, fixed, and variable-length record access methods, transactions, locking, logging, shared memory caching, database recovery, and replication for highly available systems. DB supports C, C++, C#, Java, PHP, and Perl APIs. It supports key-value pair (NoSQL), SQL, and Java Object formatted data. It is available for a wide variety of Unix platforms as well as QNX, Android, Mac OS X, and several varieties of Windows.
Berkeley DB XML is a native XML database engine for use within your product. Made available as a C++ library with language bindings for Java, Perl, Python, PHP, and Tcl, it integrates directly into your application (it is not a standalone database server). It provides XQuery access into a database of document containers. XML documents are stored and indexed in their native format using Berkeley DB as the transactional database engine.
SQLite is a small, fast, embeddable SQL database engine that supports most of SQL92, including transactions with atomic commit and rollback, subqueries, compound queries, triggers, and views. A complete database is stored in a single cross-platform disk file. The native C/C++ API is simple and easy to use. Bindings for other languages are also available.
Riteway-Reorgs is a Tcl/TK GUI and Batch program to reorganize ISAM data files that are exclusive to the Synergy/DE product of Synergex International Inc. It lets you maintain peak Synergy/DE ISAM file and application performance. It requires an operational installation of Synergy/DE. It is built as a Tcl DevKit wrapped stand-alone executable, and requires the ActiveState Tcl DevKit to build.
WordNet® is an on-line lexical reference system whose design is inspired by current psycholinguistic theories of human lexical memory. English nouns, verbs, adjectives and adverbs are organized into synonym sets, each representing one underlying lexical concept. Different relations link the synonym sets.
