SAP HANA XS (Extended Application Services) is an application server embedded within the SAP HANA platform. It enables developers to build, run, and deploy lightweight web-based applications directly on the SAP HANA database. XS leverages the in-memory computing power of SAP HANA to provide real-time data processing and analytics combined with application logic, making it a powerful tool for SAP developers.
This article covers the essential steps and best practices for building and deploying SAP HANA XS applications, designed for SAP professionals and developers who want to harness the full potential of the SAP HANA platform.
SAP HANA XS is an integrated application server within SAP HANA, supporting JavaScript-based server-side programming and providing a runtime environment for web applications. It offers:
Before starting development, ensure you have:
In SAP HANA Studio or Web IDE, create a new repository workspace or XS project.
Define your project structure, which typically includes folders for:
db/ — for database artifacts (tables, views, procedures)src/ — for application logic (XSJS files)ui/ — for user interface resources (HTML, CSS, JS)XS applications rely heavily on the underlying database design. You can create:
Define these artifacts using SQL or the SAP HANA modeling tools.
XSJS (Extended Application Services JavaScript) is the server-side scripting language for XS applications.
.xsjs files to implement application logic such as data processing, API endpoints, and business rules.Example XSJS code snippet:
var conn = $.db.getConnection();
var pstmt = conn.prepareStatement("SELECT * FROM MY_SCHEMA.MY_TABLE");
var rs = pstmt.executeQuery();
var results = [];
while(rs.next()) {
results.push({
ID: rs.getInt(1),
NAME: rs.getString(2)
});
}
$.response.setBody(JSON.stringify(results));
SAP HANA XS supports web UI development:
ui/ folder or as per project structure.Building and deploying SAP HANA XS applications is a robust approach to delivering real-time, database-driven web applications in the SAP ecosystem. By integrating application logic closely with SAP HANA’s in-memory platform, XS allows for high-performance applications with seamless data access.
For SAP developers, mastering SAP HANA XS development expands their capability to build innovative solutions that leverage the full power of SAP HANA. With proper design, coding, and deployment strategies, XS applications can transform business processes with agility and speed.
