Building Location-Aware XSA Web Applications using Python

Visualization is the key to effective communication. If you can paint a picture for your audience that is easy for them to visualize, it becomes so much easier to get your point across. When it comes to communicating enterprise data, what better tool to use than a map that can intuitively show complex data in a graphical way that is both useful and interesting for the audience. In this blog, I am going to introduce you to the geospatial processing capabilities of SAP HANA and how you can leverage them in a web application involving maps.

Update SAP B1 rates using HANA XS and ServiceLayer

In this post we will do the same but using HANA XS as the development and administrating tool and B1 Service Layer as the data interface. This approach is applicable to SAP Business One version for HANA since SQL Server version doesn’t support neither XS nor ServiceLayer. After you have performed all steps you can schedule currency rates updating using standard HANA tools to update your rates regularly. This application updates rates for all currencies in your company using ECB (European Central Bank) web-service. Rates are updated according to company rate direction (Direct/Indirect rate) and using Euro cross-rate (in case the local currency is not Euro). Company details are passed in job settings.

Upgrade HANA Express and optimize memory usage

As every few months an updated release of SAP HANA Express Edition is available a regular task is upgrading the own HANA Express to gain bug fixes and new features and simply stay up to date.

Developing Speech Interface for XSA Web Applications using Python

In this blog, I am going to talk about how to build conversational interfaces in XSA applications by integrating speech-to-text and text-to-speech APIs. I am also going to briefly cover how web sockets work in python for XSA applications. For those that are not familiar, web sockets are used for live bi-directional communication between clients and a server. Numerous clients can be connected to the same server through which they receive live updates as events. They do not need to make explicit HTTP calls to check for status updates. In addition, the Server can also initiate communication with the client and send updates as opposed to simple HTTP where a client must always initiate communication often leading to polling interfaces.

Example Optimize Join Columns

In this example we will demonstrate how the usage of option Optimize Join Columns influences query processing. The example makes use of two tables.

Examples Using Input Parameters with Calculation Views

Input parameters provide a means to influence query execution with values that are entered at runtime by the end user. In contrast to variables, input parameters can be mapped between different views so that an input parameter from one view is filled with values of the mapped input parameter of another view. In addition, it can be controlled at what node the input parameters are processed which provides precise control about the semantics of the input parameter. While variables are evaluated using the normal WHERE-filter Syntax, input parameters offer more options and have an own syntax. We will demonstrate this syntax of input parameters with different examples in this blog.

Working with HANA spatial data in Javascript

Over the years, I’ve done a fair amount of technical proof-of-concept applications, most of them on HANA or the SAP cloud platform. All of these have been written up into step-by-step “how-to’s”, but precious few of them have found their way here, to the public realm.
