#1: Why and What

SAP® Cloud Application Programming Model(CAPM) is a set of Library, Tools, Language and Framework from SAP® for building Apps.

The main reason for creating CAPM is to

Provide a Simple way to Create Cloud-Based Apps
The Apps and code which developer created can be made more reusable as modules
Advantage of Microservice can be utilized
Apps in Cloud can be easily integrated with Cloud Services(like DB service, message broker service or Auth Provider service)
A developer can focus more on the functional side of problem-solving

The 2 main Principle of SAP® CAPM are:

Declarative Approach: Focus on Outcome, not on Way!
Service-Based Approach: Get the Functionality from Service

Declarative Approach

So, if you are a developer you need to focus more on understanding the functional side which is what customer needs now, and also thinking about how can the App/Platform you are developing will evolve over time. Keeping this in mind you need to keep your current development modular, so it can allow future changes easily or your current development can be reused in the future easily.

Service-Based Approach

In CAPM all functionalities need to be broken down as service(s). In CAPM Services are stateless which means there is no record of previous interactions and each interaction request has to be handled based entirely on information that comes with it. You will also see, that to implement new service/functionality we will many times query existing service(s).

#2: Developer Stack

That Sounds Great! But you might be having questions like How it is Build and How as a developer you will work with it?

CAPM Lib are Predominantly Build With NodeJS, so you need to have basic know-how of NodeJS
We will use a lot of CDS code, may it be for building data structure(entity model/Table Structure), creating services(with functions) or even creating UI(with CDS Annotations)
You will find many out of the box tools which are part of CAPM, for example for running Apps with Fiori® Preview just with developed service, for building data structure to deploy in Database like HANA®, Sqlite or Other Other and many more surprises!

Prerequisite and Getting Started

We will create a simple End-to-End CAPM App using HDI Container in SAP® Cloud Foundry from Scratch.

Regarding Prerequisites:

Basic knowledge of NodeJS is required
Basic knowledge of SAPUI5 is required
Basic knowledge of CDS is required

My new year Resolution for 2017

UI5CN is a learning platform and the highest form of knowledge we can acquire is wisdom. We might be in many different situations, many plans may be there in our mind, many challenges we can foresee for that plan to become reality. But the big question is not what is stopping us or may stop us but what keeps us going. And the inner why, which is the reason we do what we do.

Let it tell us not to settle for less and it is not ok to, not to strive for greatness.

So let’s start the New Year with new possibility and believe to be more than what we were.

Sweet Story of SAPUI5/OpenUI5 and Javascript

Javascript has become new norms for developing applications. Processing at the UI end is becoming more fashionable and every major software-related companies are having their own JS framework. For enterprise giant SAP, SAPUI5/Open UI5 is the new framework. Google and Facebook also have their own framework Angular.js and React.js respectively which are few among the top.

The world is changing for good, some may disagree!

When we take a closer look at SAP, ABAP or ABAP/4 was used majorly to create enterprise application and there was a lot of development done with SAP ABAP editor which is inbuilt with SAP Frontend UI also eclipse was second popular IDE used to write ABAP code.

We also saw the introduction of Web-Dynpro a few years back to leverage Java for developing enterprise applications. After Sun Microsystem was acquired by Oracle and Oracle and SAP are a well-known competitor in the ERP marketplace it was clear for SAP to move away from Java world. Then comes the era of Javascript. In the meantime in the Javascript world after ES6 version of Javascript the possibility and things you can perform were impressive and with HTML5 not only you can leverage the responsive nature of building a mobile application but also can make it much much better looking with CSS3.
And With these open source technologies, UI5 was created.

Now comes the major challenge to replace all existing application in SAP with UI5, the answer was SAP Fiori, Fiori means flowers in Italian and apps build with UI5 do follow 5 basic guideline principles to make it look beautiful as a flower. SAP Fiori was launched with 25 applications with HCM, Timesheet apps few popular among the first 25 apps. Now the portfolio of Fiori apps is much bigger covering a wide spectrum of functional fields and more than 500+ apps.

When we try to predict the future with SAPUI5/Open UI5 and Fiori, we are going to see more of open source stacks coming in like Node.js and Angular.js influence with UI5.

Now the major question comes here: Is it worth learning UI5 or if you are already a UI5 developer it is worth spending time to upgrade the skills and the answer is yes!

Till now we have only seen the tip of the iceberg and there is a lot more to come. At UI5CN we spend a lot of our time( as we don’t have anything else to do) to help people who are starting their career with SAP or upgrade their skills to go to the next level.

7 Reasons To Learn UI5

This blog will pinpoint 7 major reason why UI5 is worth considering if you are looking forward to learn it, to set the context check our previous blog the Sweet Story of SAPUI5/OpenUI5 and Javascript. Basically, UI5 is open source Javascript library build with Javascript, jQuery, HTML5 and CSS3. Using UI5 we can create HTML5 applications, which can then be run in web browser.

1.Open Source

Open UI5 libraries are open source which means that you pay zero licensing cost to use Open UI5 technologies. If you are creating an app with UI5 it comes under Apache License open source version 2.0 licences and the goals of this licence is to reduce the number of frequently asked questions, to allow the license to be reusable without modification by any project, to allow the license to be included by reference instead of listed in every file etc. Read more about Apache License version 2.0 here.

2.Integrate with existing JS libraries:

SAPUI5 and OpenUI5 are created using with Javascript so the integration with existing pool of Javascript libraries are easy, UI5 internally uses D3JS analytics libraries to leverage graphs and data representation in nice and beautiful visual forms. In our Advanced UI5 Professional course we have covered this in details of how to add an external libraries elements as components in UI5 itself . See more here.

3.Pre-Build Elements

UI5 libraries are equipped with 200+ pre-build elements which allows developers to focus on UX designs of their application and the integration with the existing application of these components which are object based and simple once you know the basic working of MVC with UI5.

4.MVC

An UI5 Application utilizes MVC framework which clearly separated Model, View and Controls for an existing application and designing complex application with this pattern is much simpler.

5.Responsive

When you create a UI5 application with responsive component the component change it’s shape and size to adapt depending upon type of device they are currently being operated on. Thanks to media query of CSS3 which allows it to do so. It provides a much needed benefit to make sure that apps are usable independent of what device your end-user is using to run these apps. Even with custom CSS and media query we can make the look and feel of the application even more customised which we covered in details in our Professional UI5 development course.

6.Loose coupling Architecture:

When we talk about big picture of how these UI5 application are deployed in landscape. They are basically following loose coupling architecture which means the UI5 components are independent of the middleware components and backend. This provides a good degree of separation when we talk about coming up with new version of your application. Your middleware can be a oData service provider like SAP Netweaver gateway or SAP Hana system. Middle ware development is one of the curtal part in any application now as most of the data fetching performance is based on that. Learn how it can be done in details here.

7.Comprehensive API reference:

Finally, API reference provided by SAPUI5/OpenUI5 is comprehensive which helps a lot to understand how to use these libraries. The explored provided is a big help to see how individual component will look like and what are the code to be written to include it.

Some of the disadvantages related to UI5 is it’s initial high loading time of libraries, that means libraries can take time when they are initially loaded in your web browser this can also be fixed by using early loading concepts .

Check some of our Free and Paid resources to learn UI5 here, these are made by people who knows a lot about UI5 but are too lazy to work as consultant/contractors 🙂

The Millennials – Exploring the World of the Largest Living Generation

It was my first job at a reputed MNC and I was excited, the culture of the organization was so much different it was vibrant and diverse. One thing which I found that the average age of the organization was quite low which was around 28 at that time, most of the workforce was comprised of people, what we refer as to as Millennials. Born between the early 1980s and 2000, the millennials are the youngest (and on several occasions, the largest) generation at work today.

There is a distinct way in which Millennials think, want to work and want to be lead. I could easily experience that people who were Generation X and Baby boomers, who were mostly in the leadership role were finding it a little challenging to deal with majority Millennials. That gave me the motivation to know more about them and how to effectively work with them. This has made my life so much easier now because a majority of my co-worker were Millennials. Even though I am a Millennial too, just sticking to management book and old school way of leading team created a discrepancy.

In this video, Author of the book The Millennials – Exploring the World of the Largest Living Generation Subramanian S. Kalpathi has addressed the issues related to Millennials in the workplace today with lots of case study and real life examples.
