Mobile Business Objects: MBO Concept and Creation

Sybase Unwired Platform Article Series #4

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

  1. Connect to the back-end data sources that need to be mobilized, via the Unwired tooling
  2. Connect the Unwired tooling to the Unwired Server
  3. Create a Mobile Application Project
  4. Create the MBO from the data source via wizards or Create the MBO attributes and Create, Update, Delete Operations seperately
  5. Deploy the MBO's to the Unwired Server

Diving a bit deeper the MBO is...

  • A metadata definition representing a “slice” of enterprise data and operations
  • A design-time element that manifests as a concrete runtime object
  • The building block for synchronization and transaction of multiple elements of an application
  • Personalization keys (device context) helps narrow data sets  *see below
  • MBOs are the basis for concrete Objective-C, C# and Java device-side object interfaces

Mobile Business Objects

Development Paradigm

Attributes (synchronized data)

  • Define the scope of the device-side data store
  • Attributes and parameters in an MBO definition form the shape of the server-side cache
  • Server cache and device is populated by reading data from the enterprise, e.g., through an MBO definition operation like a SQL select statement

 

Operations (enterprise playback)

  • Backend tasks to be carried out within the enterprise or through an external service, typically with respect to the MBO attributes


Parameters

  • Can be passed to one or more operations
  • Linked to upstream parameters or attributes
  • Defined by personalization keys for a user or group *see below


Relationships

  • Form the basis of transactions by identifying the dependencies and state requirements of device-side entities
    Relationships are formed by mapping attributes and parameters similar to a primary-foreign keys

Design Deploy Test

How does SUP perform its functions?

  1. Design or Modify in the Designer Mode through the GUI interface to define/Edit “Mobile Business Objects”
    Use tooling set preferred (Eclipse or Visual Studio)‏
  2. In designer mode, the SUP tool generates the SQL and code operations for the devices and server side apps and any addition API, filtering and so forth occurs in this phase. Then package and deploy.
  3. In operation or runtime mode,  SUP Runtime engine then performs the synchronization/loads and relationship management as specified by the MBO runtime parameters

Sybase Unwired Platform offers flexibility when creating mobile applications – catering to the needs/requirements of both novice and advanced mobile developers.

 

For iSurvey I used the Bottom-Up approach and the wizards in the Unwired Tooling to create a 1:1 representation of the tables that I wanted to synchronize onto Mobile Client.

iSurevey MBOs


Personalization keys helps narrow data sets... For iSurvey each user will be placing data (contacts and survey results) into their own remote database via the app and will not want to see the data from other users, likewise specific surveys may wish to be pushed out from the consolidated database to individual users. For this we use Personalization keys on the defined MBOs, for example Survey_contact

Personalization Key Definition

Personalization Key Usage

Looking to the next step... Developers have two choices when creating native applications in Sybase Unwired Platform...

  1. Create MBOs that connect to back-end data sources then use Sybase Unwired Platform to generate code warapper for the targeted device and code further using the native device SDK
  2. Create MBOs that connect to back-end data sources, use Sybase Unwired Platform to generate the default device GUI and then further customize the GUI for a device-specific user experience using the native device SDK.

For iOS #1 is the only option and we will go into that further...

The Internet of Things is tied together with a thin strand that is known as time. Coincidentally, at the core of nearly all data analytics is a timestamp. When working with time series data there are a few core principles that everyone should consider, especially across datasets where time is the common boundary. In his session at Internet of @ThingsExpo, Jim Scott, Director of Enterprise Strategy & Architecture at MapR Technologies, discussed single-value, geo-spatial, and log time series data. By focusing on enterprise applications and the data center, he will use OpenTSDB as an example t...
The industrial software market has treated data with the mentality of “collect everything now, worry about how to use it later.” We now find ourselves buried in data, with the pervasive connectivity of the (Industrial) Internet of Things only piling on more numbers. There’s too much data and not enough information. In his session at @ThingsExpo, Bob Gates, Global Marketing Director, GE’s Intelligent Platforms business, to discuss how realizing the power of IoT, software developers are now focused on understanding how industrial data can create intelligence for industrial operations.

As Big Data growth continues, organizations are demanding real-time access to data, allowing immediate and actionable interpretation of events as they happen. Another aspect concerns how to deliver ...
Scott Jenson leads a project called The Physical Web within the Chrome team at Google. Project members are working to take the scalability and openness of the web and use it to talk to the exponentially exploding range of smart devices. Nearly every company today working on the IoT comes up with the same basic solution: use my server and you'll be fine. But if we really believe there will be trillions of these devices, that just can't scale. We need a system that is open a scalable and by using the URL as a basic building block, we open this up and get the same resilience that the web enjoys.
The Internet of Things will greatly expand the opportunities for data collection and new business models driven off of that data.
