GraphQL Consume web services The general principle of GraphQL is to make a single request to the web service, specifying all the data you want to retrieve. The server returns all the data requested, structured in JSON format. This offers a clear advantage, as you make one call instead of many. Performance is unmatched by any other type of web service.

HFSQL: Semantic search AI-based index HFSQL 2026 introduces an incredible new feature: The ability to perform "semantic" searches, i.e. searches based on the meaning of text, rather than on the exact string. This search examines text items or memos. A new index format (.vex) has been added to HFSQL. It can be used without any adaptations, as it is natively supported by HFSQL.

OpenStreetMap: Use maps without Google Maps
Google Maps is an extremely powerful and popular mapping service. However, there are numerous other mapping platforms. OpenStreetMap is the best-known alternative. Options available WINDEV, WEBDEV and WINDEV Mobile 2026 (Android apps) support OpenStreetMap. You can easily choose the type of map in the 7-tab window of the control. Please note that OpenStreetMap and Google Maps offers different functionalities. Both solutions support gestures (zoom, move, etc.), and allow users to draw routes, shapes, points of interest, etc. However, some automatic features are not available, in particular route planning and marker clusters.
