SOA in the Cloud It's Thursday morning, you're the CEO of a large, publicly traded company, and you just called your executives into the conference room for the exciting news. The board of directors has approved the acquisition of a key competitor, and you're looking for a call-to-action to get everyone planning for the next steps. You talk to the sales executives about the integration of both sales forces in three months time, and they are excited about the new prospects. You talk to the HR director who is ready to address the change they need to make in two months. You speak to the buildings and maintenance director who can have everyone moved that needs to be moved in three months. Your heart is filled with pride. However, when you ask the CIO about changing the core business processes to drive the combined companies, the response is much less enthusiastic. "Not... (more)

Mobile Business Objects: MBO Concept and Creation

The design cornerstone of the Sybase's MEAP the Sybase Unwired Platform is the Mobile Business Object (MBO). The MBO encapsulates the business process logic and data into a reusable unit that can be accessed from a variety of clients. The development can take two approaches,  firstly the Top-Down approach, which creates the MBO based upon how the client wants to use it... eventually binding to the data source. Secondly, the Bottom-UP approach which uses the data source to automatically bind and create the MBO. Both use the Unwired tooling and are easy to create, with similar steps listed below Connect to the back-end data sources that need to be mobilized, via the Unwired tooling Connect the Unwired tooling to the Unwired Server Create a Mobile Application Project Create the MBO from the data source via wizards or Create the MBO attributes and Create, Update, Delete...

Showplan Basics, Optimize your SQL

As developers, we often focus on code and give less attention to the database than we should. Developers on large development teams, who can usually rely on the database programmers and/or DBA to write and optimize their SQL, tend to shy away from anything database related. On smaller teams the developers are responsible for the schema and DML, but typically don't understand the nuances and complexities of the specific database they're working with. A very important yet undervalued feature in PowerBuilder's database painter, "Explain SQL," takes advantage of the database engine's query analyzer (Showplan report) to show pathing and performance information about a SQL statement. Every developer should know how it works and how to use it. In this article I'll describe the report and show you how to use it to optimize your SQL. Before you can begin to tune your SQL, y...

A Current Row Indicator for HTML DataWindows

One of the typical problems developers face when using the HTML DataWindow (HTML DW) is that there's no SetRowFocusIndicator() method to allow users to see which row is the current one. This can confuse the user and lead to errors. For example, without a current row indicator users may not know which row will be deleted when they press a Delete button. This article describes a simple and effective technique for addressing this problem. The Solution Figure 1 shows an HTML DW with a current row indicator pointing at the second row. The key to the proposed solution is that it avoids the need for a round-trip to the server. It simply uses the RowFocusChanged event to set the text in a Pointer computed column to "<<<" for the current row and to a blank (" ") for all other rows. Changes to the DataWindow Object As a first step, open your DataWindow object in the DataWindow... (more)

Handling Aborted Transactions in Jaguar

In this article we'll examine how to handle a Jaguar CORBA_TRANSACTION_ROLLEDBACK exception that is thrown when a Jaguar transaction is aborted. We'll use the BTFBank sample application developed in an article I wrote for PBDJ in October 1999 (Vol. 6, issue10). This example is written in PowerBuilder, but the technique covered here is relevant for any Jaguar client (Java, Web, etc.) or Jaguar component that's involved in a transaction. When developing a Jaguar component that uses Jaguar transactions, a CORBA_TRANSACTION_ROLLEDBACK exception is generated each time a transaction managed by the Jaguar server is aborted and rolled back. A transaction is marked as requiring a ROLLBACK by a PowerBuilder component's invoking the SetAbort function on the TransactionServer object. This exception is thrown when the method that's called on a Jaguar component causes the trans... (more)

Concepts in Graphing

When I sit down to write this column I always ask myself, "What can I write that will be the most help to DataWindow programmers?" At the moment I'm also in the final production stages of my new book, The Definitive DataWindow. This morning, while glancing at my chapter on "Graphing," I remembered that this is an area not well understood by many people. In addition, an awful lot can be said about graphing, maybe enough for a series of articles. My goal right now is to make sure you're an expert at creating graphs. I'm going to show you how to create them, how to use computed columns to make the data "fit" into your graph and how to make them interactive. I probably won't be able to fit it all into just one article - but I'll try. We're going to develop an application that holds examples of graphs. Actually, this is my typical test application. I write one for every ... (more)

Things Are Looking Up

I have been disappointed by the last few Sybase conferences. Overall they were fine, but Sybase didn't successfully use them to alleviate fears that the company was in decline. The stock price was down, analysts and press were negative, Sybase's vision was a mystery and phantom marketing was successfully keeping the Sybase products hidden from the market. Nashville in '97, LA in '98, Orlando in '99...we saw a steady decline in the quantity of vendors as well as the waning interest of industry press and analysts. At its worst, last year's press day was canceled without reason. I think it was because so few press and analysts showed up that Sybase was embarrassed by the low turnout. Things are looking up. At TechWave 2000 there were so many press and analysts that it was standing room only at the press events. I counted over 50 people, and they were a very internation... (more)

Two Heads Are Better Than One

After careful consideration I've come to the conclusion that having two heads is better than having just one. While it may sound like I'm simply stating the obvious, in fact, most people have only one head.1 However, those who are blessed with two heads enjoy a measurable advantage over their single-headed rivals. This conclusion was affirmed in a headline-grabbing paper by two Princeton economists for the National Bureau of Economic Research entitled "Are Two Heads Better Than One?"2 Having multiple heads is most beneficial when performing work that requires multitasking, such as speaking on two phones at the same time. Though that may seem like an inconsequential skill, how would your life change if you never had to put anyone on hold? Or you could speak to both your children at the same time? Or you could see behind you? Or never lose at a game of Trivial Pursui... (more)

EAS and DHTML Tab Controls

After years of considering what types of controls to put in a Web page, the main technologies that work are ActiveX, Java and DHTML. I thought only Java or ActiveX could provide the types of controls I needed, until I saw the game Asteroids, written in DHTML. If you haven't seen it, here's the link: http://msdn.microsoft.com/workshop/Author/dhtml/tutorial/asteroids/asteroids.htm. Although this is an old link now (in Internet terms), it's still impressive. DHTML (Dynamic HTML) is lightweight compared to Java and ActiveX. Taking this into account, along with a few other considerations, I lean toward a DHTML solution for creating controls inside a Web page. Recently, middle-tier server software has added another dimension to the process of creating dynamic content. EAS from Sybase provides Jaguar and Dynamo, which can combine to drive a rich Web site. The reality of Web ... (more)

Getting from PowerBuilder to the Web (Revisited)

There seems to be a lot of "sound and fury" concerning the move from PowerBuilder to the Web. I'm convinced, however, that the majority of PowerBuilder developers don't know how to get there. Many of those who have taken that course have found it more difficult than they first anticipated. If you're in the latter boat, perhaps this article won't be of much interest to you - you've already earned your battle scars. For those of you who have yet to venture into the minefield, perhaps I can guide you along the way. I believe one of the problems PowerBuilder developers face when trying to move to the Web is the variety of options on how to get there. There's the DataWindow plug-in, the window plug-in and ActiveX, and the PowerBuilder Web Deployment Kit. Other options include generating HTML pages from PowerBuilder using the SaveAs() and GenerateHTMLForm() methods, access... (more)

IMHO - On Starting a PBUG

Several years ago I realized that the Tulsa PBUG (PowerBuilder Users Group) was defunct. After talking to those involved it became clear that interest had waned and there was little officer support - the group died of starvation. It seemed that here was a great opportunity. Since I had taught a couple of semesters of Advanced PowerBuilder at Tulsa Community College, I knew there was an increasing number of PowerBuilder developers in Tulsa. Most of them would enjoy the chance to network with fellow developers and pick up some much needed PB gossip and techniques. Information Gathering and Organizing I attended the 1999 TechWave in Orlando, and (plot brewing in my mind) went to the PBUG Presidents meeting to listen to the various points of view, find out what a PBUG could be and what was working and failing across the country. It was an informative meeting and there see... (more)

What do you get when you combine Big Data technologies….like Pig and Hive? A flying pig? No, you get a “Logical Data Warehouse.” In 2012, Infochimps (now CSC) leveraged its early use of stream processing, NoSQLs, and Hadoop to create a design pattern which combined real-time, ad-hoc, and batch analytics. This concept of combining the best-in-breed Big Data technologies will continue to advance across the industry until the entire legacy (and proprietary) data infrastructure stack will be replaced with a new (and open) one.
While unprecedented technological advances have been made in healthcare in areas such as genomics, digital imaging and Health Information Systems, access to this information has been not been easy for both the healthcare provider and the patient themselves. Regulatory compliance and controls, information lock-in in proprietary Electronic Health Record systems and security concerns have made it difficult to share data across health care providers.

Everyone talks about a cloud-first or mobile-first strategy. It's the trend du jour, and for good reason as these innovative technologies have revolutionized an industry and made savvy companies a lot of money. But consider for a minute what's emerging with the Age of Context and the Internet of Things. Devices, interfaces, everyday objects are becoming endowed with computing smarts. This is creating an unprecedented focus on the Application Programming Interface (API) as developers seek to connect these devices and interfaces to create new supporting services and hybrids. I call this trend the move toward an API-first business model and strategy.
We live in a world that requires us to compete on our differential use of time and information, yet only a fraction of information workers today have access to the analytical capabilities they need to make better decisions. Now, with the advent of a new generation of embedded business intelligence (BI) platforms, cloud developers are disrupting the world of analytics. They are using these new BI platforms to inject more intelligence into the applications business people use every day. As a result, data-driven decision-making is finally on track to become the rule, not the exception.
