Servertec Persistent Object Store .NET Edition Announced
Servertec announced the release of Servertec Persistent Object Store .NET Edition, an object-oriented database engine that runs with Microsoft s .NET Framework.
Using Persistent Object Store (POS), developers can create standalone database applications that run on any platform that supports Microsoft s .NET Framework version 1.1 or later. POS is built around an optimized multi-threaded database engine, and can be used from C#, Visual Basic, C++, J#, or any other .NET programming language. The POS API is similar to System.Collections.Hashtable or java.util.Hashtable, and doesn t require SQL, ODBC, JDBC, or object to relational mapping.
POS supports individual object locking, so there is no need to block threads while a group of objects are locked during update operations. The locker allows multiple read locks and a single write lock on each object.
POS enumeration filters and index filters reduce the need to transport and process key/value pairs that do not match the specified criteria.
POS includes an optimized serialization engine for storage and retrieval of primitives, strings, blobs, and serializable objects. Using POS, developers can create persistent objects without having to deal with object to relational mapping. POS is fully configurable; using the API, all aspects of an object store can be specified. POS uses hashing with linked overflow for collision resolution when storing objects, and uses modified B-trees for storing objects in indexes. POS supports input, output, and random streams.
POS ships with examples (including source code) that demonstrate many of its key features, as well as online documentation (available as Web pages). POS also includes utilities for checking the integrity of object stores and indexes and utilities for recovering value pairs from damaged object stores and indexes.
A free 90-day preview release is available at the Servertec Web site.
Price: End-users can license POS on a per-server basis for US$25; site licenses start at US$250.
