Setting the Scene and Overview of a MEAP

Sybase Unwired Platform Article Series #1

As I said in the initial article SUP is a Mobile Enterprise Application Platform (MEAP), which in my opinion and also of folks like Gartner, is the only way forward in multiple application mobilization and multiple device support. SUP abstracts the data access and Business Logic into Mobile Business Objects (MBO's) that take care of accessing, updating and deleting back end data. That data could be from files, corporate RDMS and other 3rd party systems such as SAP. If you are on LinkedIn and interested in MEAPs be sure to join the Mobile Enterprise Application Platforms group and take part in the discussions.

Below is a high level architecture diagram of Sybase's MEAP the Sybase Unwired Platform.

SUP Architecture

I can hear you all now... 'But what application was project going to build?

What I decided to code was something that was created four years ago in Sybase PocketBuilder called PocketSurvey, or as I have renamed it, following in the way of iOS applications... iSurvey. Basically iSurvey is a Survey or Lead Retrieval system, which allows the synchronization of many Surveys, into a SQLite database on the iOS device. These Surveys are created in the back-end database containing many questions, and a number of possible answers to each question. Once synchronized to a device the user can approach leads etc and get contact information from them (name, email) and iSurvey will also capture where the contact was approached (via Apple's Core Location Framework). Once the contact is captured in the system, then the appropriate survey can be performed and answers captured, to be synchronised back to the back-end SQL Anywhere database.

Here is a video showing iSurvey

It is a simplistic application, that has a few limitations (such as its single choice answer format), but works and shows the capabilities of SUP and iOS together. if I wanted to take the project further I could additionally develop a client for Windows Mobile and Blackberry.

WebRTC sits at the intersection between VoIP and the Web. As such, it poses some interesting challenges for those developing services on top of it, but also for those who need to test and monitor these services. In his session at WebRTC Summit, Tsahi Levent-Levi, co-founder of testRTC, reviewed the various challenges posed by WebRTC when it comes to testing and monitoring and on ways to overcome them.
DevOps is being widely accepted (if not fully adopted) as essential in enterprise IT. But as Enterprise DevOps gains maturity, expands scope, and increases velocity, the need for data-driven decisions across teams becomes more acute. DevOps teams in any modern business must wrangle the ‘digital exhaust’ from the delivery toolchain, "pervasive" and "cognitive" computing, APIs and services, mobile devices and applications, the Internet of Things, and now even blockchain. In this power panel at @...

For basic one-to-one voice or video calling solutions, WebRTC has proven to be a very powerful technology. Although WebRTC’s core functionality is to provide secure, real-time p2p media streaming, leveraging native platform features and server-side components brings up new communication capabilities for web and native mobile applications, allowing for advanced multi-user use cases such as video broadcasting, conferencing, and media recording.
Web Real-Time Communication APIs have quickly revolutionized what browsers are capable of. In addition to video and audio streams, we can now bi-directionally send arbitrary data over WebRTC's PeerConnection Data Channels. With the advent of Progressive Web Apps and new hardware APIs such as WebBluetooh and WebUSB, we can finally enable users to stitch together the Internet of Things directly from their browsers while communicating privately and securely in a decentralized way.
