Infostructure Inc, San Francisco, California, has introduced Structure, an object-oriented graphical application development tool for Unix and Microsoft Windows NT. According to Infostructure, the software is designed to enable users to write applications graphically without writing code manually. To do this, it provides an application framework (a template), which enables users to develop applications from a set of C++ class libraries including graphics, icons and scrollers. Structure comprises three layers. At the top, there is an application class level, which enables users to define object notations and the behaviour of an object itself. From here, a series of subset objects called documents are created (users can decide how many documents they require), which controls corporate data. Documents can control database systems, communications between different hardware and software systems, networks and applications, Infostructure says. At the client level, a graphical user interface object-based front-end enables users to view, modify and manipulate information. Structure is available now on Hewlet-Packard Co and Sun Microsystems Inc systems – and support for Windows NT will be added by the end of the year. It is priced at UKP1,650.
