What is it?
• A library that links directly into your application. It allows your
application to transparently store and query data, without
incurring the client/server overhead.
• Provides very fast, highly reliable, scalable, recoverable local
data storage, with zero external administration.
• Used extensively in middle-tier, edge and mobile applications,
often serving as part of the enabling infrastructure, gateways or
as the mobile data repository.
• It allows you to do more with less, through high performance,
reliability, small footprint and flexibility, It’s lower TCO is
especially attractive to customers and partners.
