San Francisco, California, Karlsruhe, GermanyﾑDecember 1, 1995:
theta group and dtF Americas, Inc. announced dtF version 1.6 for C/C++, Peregrine, HyperCard, SuperCard, SmalltalkAgentsｪ and Apple Media Toolkit developers of the most powerful relational database system for Apple Macintosh computers. dtF provides a premier choice for developers who want to create high powered database centered applications with no performance trade-offs. dtF features native PowerPC, SQL, binary large objects, full transaction control, error recovery, client server architecture, OpenDocｪ and multi-platform support. Third-party vendors supporting dtF will be able to offer a wide variety of advanced features and benefits to their customers royalty-free.
"dtF v1.6 is an important milestone in our database components strategy" stated Hans Martin Kern, Vice President of Product Management & Engineering, theta group, "Our unique direct integration technology ensures a seamless integration with innovative development environments like Metrowerks CodeWarrior, Peregrine, SmalltalkAgents or the Apple Media Toolkit. dtF's early adoption of OpenDocｪ technology allows software developers and end-users to take advantage of component software benefits within their client/server database environments today."
dtF v1.6, which will ship at MacWorld San Francisco '96, includes the following improvements and features
･ Numerous SQL-enhancements
DISTINCT-clause, order by ASC/DESC, full parenthesis-support in
where-clause, LEFT/RIGHT/FULL OUTER JOIN, INNER JOIN, UNION JOIN, KEY JOIN,
NATURAL JOIN support up to SQL3-level, ON-statement, complete ANSI92
datatypes implementation, IS NULL/IS NOT NULL clause, about 40 new
stack-functions for calculations, string-manipulation, automatic type
conversion, ORDER BY number for ordering by terms in the SELECT clause,
COMMENT ON table statement
･ Referential integrity (PRIMARY/FOREIGN KEYs) for built-in support of data
consistency rules including cascading updates and deletes
･ Column constraints NOT NULL REFERENCES
･ Delimited field/table/index names for inclusion of special charachters
in identifiers
･ Enhanced self-learning query optimization
･ New and revised dtF/SERVER application also available as a library for
easy customization and OEMing
･ New dtF/ADMIN application for convenient administration of dtF databases
including full table, user and index administration.
･ ODBC driver for industry-standard access to dtF/SERVER and dtF Stand-alone
･ OpenDocｪ part editors for easy frontending of dtF Databases
･ Special OpenDocｪ compatible libraries for creation of OpenDoc database part

dtF was designed specifically for personal computers in single user and client/server environments, so applications created with dtF are compact, requiring minimal hard disk space and main memory. dtF includes full transaction control and high level error recovery to guarantee maximum data protection even after sudden system crashes. dtF databases are compacted and encrypted to protect against unauthorized access. With dtF's unique direct integration technology, stand-alone database system and multi-user clients are directly contained in the application, allowing the developer to build double-clickable applications without additional INITs, drivers or other system extensions. DataScriptｪ for dtF and the dtF ODBC driver allow industry-strength productivity applications and client/server development systems to access dtF databases while ensuring that all directly integrated applications deliver the full power of dtF. Full CD-ROM support for both multimedia applications and dtF databases makes dtF an ideal choice for multimedia application developers.
dtF is targeted towards the professional application developer. There are no end-users features which raise the price and slow down the speed. dtF allows the database developer to use his favorite tools to provide the best user interface possible including HyperCard, SuperCard, SmalltalkAgents, DataScript/ AppleScript, Apple Media Toolkit, Macromind Director, MacApp, TCL, PowerPlant etc. dtF is also an integral component of the innovative Peregrine client/server development system from Pictorius Inc.
dtF tools are included for importing, exporting, creating and managing databases and users. dtF is currently available for Mac, DOS, Windows, OS/2. The C/C++ API is identical across all platforms.
Headquartered in Cupertino, California, dtF Americas, Inc. markets the dtF relational database software for multiple platforms and offers consulting services to implement client/server solutions.
Headquartered in Karlsruhe, Germany, theta group develops the dtF relational database system for the Apple Macintosh and markets dtF in Europe and the Pacific area.
