A Canadian Perspective with an Aussi Twist

I have been asked many times by various clients, students, and the IT curious about PowerBuilder: When did Sybase develop the product and how did it evolve? I keep telling this story and answering e-mails on the subject. I am now to the point where I have decided that I should have PBDJ formally publish this story for posterity. This story is solely from my own personal perspective and I'm sure that I may have a somewhat distorted view of time and space (which keeps getting worse at my age). But anyway, here is a perspective of how life (as a DataWindow) began.
In 1984, when I was the technical support manager for Cullinet Canada, Cullinet started their Personal Computer ADSO prototype, which would later become PowerBuilder. The project leader was Dave Litwack, who was in charge of the ADSO product and IDMS-DC (data communications - teleprocessing system and CICS equivalent product). Dave had a great understanding of RAD development tools and telecommunications because of his Cullinet experience. The new product was to have the same key functionality as ADSO (interesting that ORCA was basically working in 1985 in the PowerBuilder prototype because ADSO/IDMS had it), but also added a real key feature: "a smart data aware object." At that time Cullinet was experimenting with a feature called LRF (Logical Record Facility) and DB stored procedures. This object would encapsulate data handling away from the application, but would be a client piece, so there was no dependency on any DBMS. For the first part of the prototype, Dave chose a real keen "C" programmer named Kim Sheffield. John Griffin - a friend of mine from Ottawa, Ontario - was also recruited by Dave. John was an excellent mainframe assembler programmer and wanted to cross over to C. Dave had him build the "Menu" painter. In later years, John married Julie, another Cullinet developer, and she would help rewrite the Menu Painter and add Remote Debugging to PB for EAServer. Dave also wanted to have the new tool that was fully OO - object oriented. The C++ language was coming on strong and SmallTalk was the "talk of the town" for serious OO programmers. Dave wanted PowerBuilder to adopt the SmallTalk OO principles but make it easy for the business developer to use. In 1985 a crude prototype was shown to the Cullinet inside circle. The product's potential was immediately expounded by senior management (one of those being Bobby Orr - the hockey legend [another good story I can tell you sometime] - who was on the board of directors of Cullinet at that time). Unfortunately, Cullinet had serious challenges for various takeover bids by different companies, including CA (Computer Associates). CA at that time had already purchased DataCom and wanted Cullinet for IDMS. CA's mentality then was to buy out the competition, sell off any non-key products, and milk the maintenance contracts of key clients. With little or no development personnel (fired), there was no overhead and all profit. In 1986, CA was successful on a hostile takeover of Cullinet. The new PC product was considered non-essential and all developers were let go (that is why today I will never buy a CA product)!
Episode II - The Little Droid that Could In 1988, three years after the original concept prototype, PowerSoft had the code and Dave (now hired by PowerSoft) was able to hire the other programmers who worked on the original prototype (what a fluke) as they were looking for some challenging work at that time as well. PowerSoft then christened the new product "PowerBuilder" and began to enhance the code. Since they were a business solutions developer, they used PowerBuilder internally to recode and replace their VAX products. Testing was "hands-on" and very intensive under real-world developer scenarios. To get funding for this intense effort, PowerSoft partnered with HP. HP gave them a blank check after seeing a demonstration (they are also responsible for the Tilde "O" format [~Onn] for "octal" as HP was an 8-bit machine in those days). PowerBuilder became an internal standard at HP. At Microsoft's Redmond office, the people in charge of internal systems were faced with the same problems PowerSoft was trying to resolve - they needed a tool for business developers. They contacted their friends at HP and were told that PowerBuilder was the only up-and-coming tool they should look at. In early 1989, Microsoft purchased licenses for PB and was the second worldwide user. The "Royal Australian Air Force" was the first official user - makes me proud as I'm an Australian from Cooma, NSW. When I was four years old my dad took me to the University of Sydney where he was using the SILLIAC I (Sydney version of the Illinois Automatic Computer) - the first commercial computer ever built (http://members.iinet.net.au/~dgreen/silliac.html) to do the stress and strain calculations on the Snowy Mountains Hydro Electric power dams (largest hydro generation in the world even today: www.snowyhydro.com.au ), which is where I met the first "debugger" in the world ... but that's another story. The Snowy Hydro is still an active PowerBuilder site even today. Even Microsoft used PowerBuilder for their Inventory Management System, MS University Scheduling System, etc., and was "blown" away with its data prowess - especially this new object called the "DataWindow" (thanks Kim).
