VDS Object Database
|
Many VDS object database customers first tried to solve their problems with legacy databases. However, they found that they could not represent complex relationships without difficult joins and severe performance limitations.
Versants object-oriented model has a tight binding between the application
object programming language and the underlying object database model. This model correlation, which relational databases do not provide, results in significant reduction in development time, application performance improvements, ease-of-use and time-to-market benefits.
Objects furnish a better way of building software by constructing component parts that map more accurately to real world needs. A mantra of object orientation is reusability, and our customers have seen improvements on the order of 80%. When software is reused, companies achieve higher productivity. The object-based architecture of Versants ODBMS is the basis for high performance, scalable, distributed applications. The object level architecture provides fine granular locking for the highest possible concurrency, object level transportation between the client and server to optimize network resources, and unique object identity, which is the basis for both reliable distribution and replication with integrity.
In addition, Versant achieves best-in-class scalability and performance through these additional features:
Multi-threaded, multi-session client combined with a multi-threaded server
Automatic failover
Balanced use of network resources
Event notification for database events
Dual caching ensures fast access to stored objects
Logical object ID to reference objects seamlessly in memory
