Mobile Apps: Client Server or Something Else?
Mobile App
• Multiple Layers
• Device
• Administration
• Cloud
Client Server
• Multiple Layers
• Client Layer
• Middle Tier Layer
• Server Layer

#DavidConsultGrp
Documentation
Client Server
• User Guides
• ERD
• High Level Design
Mobile App
• App Download
• ERD
• Wireframes
Differences in how the work is done (SDLC) and
vocabulary can also result in variations of the
documentation.

#DavidConsultGrp
Boundaries: Client Server
• The application or part of the application enclosed by the
boundary must be a coherent body of functionality
• Persistent storage is not considered a user of the
software and is therefore on the software side of the
boundary

#DavidConsultGrp
Boundary: Mobile App
• Does the introduction of a mobile device change the
definition of where the boundary resides?
Mobile Devices
Cloud Data
Administration
and Data Entry
5
#DavidConsultGrp
Data: Client Server
• Data can be held and maintained in multiple
instantiations in any of the layers.
6
#DavidConsultGrp
Data: Mobile App
The Cloud
• Data can also be held and maintained in multiple
instantiations
Mobile Device
• Some mobile devices hold a local copy which is
refreshed once connected.
• Some devices can only access when connected

#DavidConsultGrp
Transactions: Client Server
Business enter the application from the client and engages
the logic and data layers (technically cohesive).
8
#DavidConsultGrp
Transactions: Mobile App
Front End utilizing mobile device
The client or app leverages the data from
the cloud or from a local copy.
Different devices may have unique look
and feel, but the transactions are all still
the same.
