Store and query 2D spatial geometries in Oracle Database, such as points of interest, streets, administrative boundaries. Perform queries based on proximity (how far is it?) and containment (is it inside a region?). Access hundreds of functions to filter data, measure distance relationships, an...
It’s also worth noting that APEX uses the same database that Forms does (Oracle DB), so it’s equally scalable, safe, and stable. You also retain access to important features, ML/AI modules, Spatial, and so on. The main difference is that, unlike Forms, APEX is a modern web techno...
Oracle8i introduced the interMedia bundle, that supports text data, spatial location, images, audio, and video data. You can access interMedia objects using SQL queries, manipulate their contents (such as, trim an image), read and write their content, and convert data from one format to ...
