Trailing Oracle Corp and Informix Corp announcements by several weeks, Sybase Inc says it will offer an application development for web.works, its planned Internet architecture. It promises database and middleware details in the coming weeks. The firm recommends using the forthcoming PowerBuilder 5.0 release with web.works, plus a web.sql module being readied for use against System 10 and 11, enabling developers to embed SQL statements in HyperText Mark-up Language pages, with support for Common Gateway Interface and Netscape Communications Corp Navigator application programing interfaces. A Solaris release is due this quarter, with other systems supported from next quarter. Prices start at $1,200. Sybase has also announced Powersoft Optima++, a C++ Object Linking & Embedding automation tool that uses the Watcom C/C++ compilers, plus Microsoft Corp controls and Netscape browser plug-ins. Later versions will support Java and Corba 2.0. PowerBuilder and Optima++ will share data windows, reports and a PowerBuilder repository. Optima++ supports Open Data Base Connectivity, Sybase SQL Anywhere, Data Pipeline for data migration and InfoMaker query and reporting tools. It is expected in the next 90 days.
