OData is quickly becoming the Lingua Franca for data exchange over the web.  The OData standard defines a protocol and a language structure for issuing queries and updates to remote data sources, including (but not limited to) relational databases, file systems, content management systems, and traditional web sites.  It builds upon existing Web technologies, like HTTP and RESTful web services, the Atom Publishing Protocol (AtomPub), XML, and Javascript Object Notation (JSON). SAP and Sybase iAnywhere released SQL Anywhere version 16 in March 2013, and it had many cool new features. This blog post will cover one specific enhancement, the new support for OData access to SA databases. Note:  SA 16.0 is the follow-on release to version 12.0.1. There was no version 13, 14, or 15. Background SQL Anywhere actually introduced support for SOAP and REST-based web services ba... (more)

Source Code Control

Every software development project of any significant size or complexity has a requirement for controlling the source code asset. PowerBuilder is capable of integrating with any third-party Source Code Control (SCC) tool that implements Microsoft's SCC API. However, the fact that PowerBuilder stores its code inside PowerBuilder Libraries (PBLs) and not as individual ASCII text files adds a layer of complexity to that integration. The release of PowerBuilder 8.0 in 2001 brought with it a new set of challenges in the form of a completely redesigned interface with SCC providers, inc... (more)

A Comparison of the Programming APIs Available in SAP Mobile Platform 2.3

When Sybase first released the Unwired Platform in 2008, it was intended to be a complete end-to-end development environment for mobile applications.  SUP developers would create the middle tier components (a.k.a. Mobile Business Objects), and the client application executables from a single, integrated Eclipse-based toolset.  There was a "PowerBuilder-like" 4GL screen painter, called the Device Application Designer (or DAD), that compiled down to native Blackberry 5/6 or Windows Mobile 6.5 applications.  (Yes, it's hard to imagine, but there was a time when iOS devices were not ...

Understanding the SCC Interface in PowerBuilder 8.0

PowerBuilder 8.0 was launched in conjunction with the 10th anniversary of the product and, by all accounts, it has exceeded everyone's expectations (...and there was much rejoicing!). The enhancements in this release focus specifically on three major areas - the Web, EAServer integration, and n-tier development. The introduction of workspaces and targets, and the redesigned IDE have greatly enhanced the overall usability of the tool, especially with regard to these three areas. However, there was one significant revision introduced in 8.0 that is not getting the press I feel it ... (more)

Implement Effective Source Control with PowerBuilder 8.0

Every development shop that is currently managing its PowerBuilder source code with a third-party SCC tool and has not yet migrated to PB8 will need to understand the upcoming changes in methodology before attempting a migration. Even PBNative users will be affected, as that interface has been redesigned to use the SCC interface as well. In my previous article, "Understanding the SCC Interface in PowerBuilder 8" (PBDJ, Vol. 8, issue 11), I outlined the sweeping rewrite of the source code control (SCC) interface introduced in PowerBuilder 8.0. This article walks through some simp... (more)
