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 allowed to play in the Enterprise Mobile Application playground...)
Several market forces emerged around that time and started to cast doubts on the wisdom of the "complete end-to-end" strategy. Those were (in no particular order or importance):
- The release of the iPad, and overall growth of iOS in the enterprise mobile space;
- The subsequent struggles of RIM and Blackberry to maintain their place in a market they had been dominating;
- The fact that there were hundreds of thousands of developers already proficient in languages like C#, Java, and Objective-C;
- The emergence of OData as the primary protocol for data exchange over the web and HTTP;
- The rise of HTML5 as a cross-platform alternative to native mobile application development;
- The introduction of the Google Android platform, and it's ascendence in the mobile marketplace;
- The acquisition of Sybase by SAP, which infused the product with fresh new ideas (and a lot more development resources...)
It became fairly evident that the DAD was very dependent upon market trends and an ever-expanding variety of mobile platforms that were outside SAP's control, and was not the best long-term direction for UI tooling. As a result, the DAD got sent straight to the bit bucket with the release of SUP 2.0. The direction then became one of "openness", and embracing alternative development platforms and open industry standards.
This blog post will cover the four major API's that have been released into SMP since then. We'll cover how to generate them, what their characteristics are, when to use them (and when not to). The API's we'll cover here are:
- The Hybrid App API
- The Native Object API
- The OData SDK
- The HTTP REST API
Note: There is a 4GL programming tool for HTML5 development in SUP/SMP, called the Hybrid App Designer. I'm not discussing that tool here, because it's integrated with the platform and doesn't require the specific generation of the API libraries. And developers are hard at work crafting a new HTML5/UI5 programming tool for SMP 3.0 that will deploy hybrid apps into the Kapsel container. This tool will be called AppBuilder.
Hybrid App API
To generate the Hybrid App API from an MBO diagram, right-click the top level folder in the Workspace Navigator, and select "Generate Hybrid App API...". Figure 1 below shows where this option is located.
This opens a wizard which has two panels. The first prompts for the MBOs to include in the generation, and the second allows you to construct the message template for any Server-initiated start point.
Native Object API
The Object API can be thought of as the "native" equivalent to the Hybrid App API, in that it exposes the MBO object model to the client UI developer, but there are two major differences:
- The Native Object API is generated into the native language of the targeted mobile platform. This list includes Objective-C and Xcode for the iOS platform, Java for both the Android and Blackberry platforms, and C# for the Windows/Windows Mobile platform. The app developer is responsible for crafting the user interface and business logic layers in the native IDE for that platform. If you plan on developing multiple versions of a mobile app, one for each popular mobile platform, then it is required to generate the Object API, and develop a separate UI/logic layer, for each of those targeted platforms.
- The Native Object API also enables full offline access to the mobile application data, because it uses Replication-based Sync (RBS) when communicating with the SMP server.
To generate the Object API for a specific language and platform, right-click the Mobile Business Objects folder in the Workspace Explorer, and select "Generate Code...". This opens a wizard with three panels. The first prompts for a saved configuration profile (if there is one). The second prompts for the MBOs to include in the generated code. The final panel is the important one, and is shown below.
Even though it’s now Microservices Journal, long-time fans of SOA World Magazine can take comfort in the fact that the URL – soa.sys-con.com – remains unchanged. And that’s no mistake, as microservices are really nothing more than a new and improved take on the Service-Oriented Architecture (SOA) best practices we struggled to hammer out over the last decade. Skeptics, however, might say that this change is nothing more than an exercise in buzzword-hopping. SOA is passé, and now that people are ...

In the midst of the widespread popularity and adoption of cloud computing, it seems like everything is being offered “as a Service” these days: Infrastructure? Check. Platform? You bet. Software? Absolutely. Toaster? It’s only a matter of time. With service providers positioning vastly differing offerings under a generic “cloud” umbrella, it’s all too easy to get confused about what’s actually being offered. In his session at 16th Cloud Expo, Kevin Hazard, Director of Digital Content for SoftL...

For those of us that have been practicing SOA for over a decade, it's surprising that there's so much interest in microservices. In fairness microservices don't look like the vendor play that was early SOA in the early noughties. But experienced SOA practitioners everywhere will be wondering if microservices is actually a good thing. You see microservices is basically an SOA pattern that inherits all the well-known SOA principles and adds characteristics that address the use of SOA for distribut...

Microservice architectures are the new hotness, even though they aren't really all that different (in principle) from the paradigm described by SOA (which is dead, or not dead, depending on whom you ask). One of the things this decompositional approach to application architecture does is encourage developers and operations (some might even say DevOps) to re-evaluate scaling strategies. In particular, the notion is forwarded that an application should be built to scale and then infrastructure sho...

Microservices are the result of decomposing applications. That may sound a lot like SOA, but SOA was based on an object-oriented (noun) premise; that is, services were built around an object - like a customer - with all the necessary operations (functions) that go along with it. SOA was also founded on a variety of standards (most of them coming out of OASIS) like SOAP, WSDL, XML and UDDI. Microservices have no standards (at least none deriving from a standards body or organization) and can be b...
