The document discusses building collaborative line of business applications on IBM Bluemix using the CLEAN stack, which includes Cloudant, LoopBack, Express, AngularJS, Ionic/Cordova, and Node.js. It describes using LoopBack to define business objects and generate REST APIs, customizing the APIs, authenticating with Bluemix services, authorizing via roles, deploying to Bluemix, using Cloudant as the database, developing locally, and building web and mobile clients with AngularJS and Ionic/Cordova.

- 2. Collaborative Line of Business ApplicationsCollaborativeLoBApplications • LoB requirements often lead to the development of new applications since standard software is not sufficient • Collaborative applications allow employees to work together synergistically to get their jobs done • Collaborative LoB applications often require the protection of intellectual property based on roles of employees • Sample scenarios – Approval workflows – Teamrooms – Travel expenses
- 3. Requirements of LoB Applications • Rapid application development – To enable citizen developers to build LoB applications – To enable innovation • Focus on business needs rather than infrastructure – Leverage cloud application platforms – Utilize DevOps • Cost efficient hosting CollaborativeLoBApplications
- 4. Requirements of LoB Applications • Access to applications via web and mobile user experiences • Integration of existing data, documents and files • Integration of existing directories and user profiles • Usage of modern and popular technologies to leverage communities, libraries and tools • Usage of standard and most common development skills – Scripting is easier than languages like C and Java – Preference is to use one language for everything CollaborativeLoBApplications
