Oracle Database provides unrivalled scalability
Oracle database technology has been designed from the ground up to provide maximum scalability from both a coding and physical perspective. Oracle Database XE is built on the same code base as it's bigger brothers; applications originally developed on XE can be ported all the way up to Enterprise Edition without the need to rebuild code.
Oracle's clustering and grid capabilities also provide unmatched hardware scalability. Oracle's Real Application Clusters technology allows you to add further storage capacity on demand.
