PT Object Database is a software that utilizes Prevayler as a storage engine. This allows for efficient storage and retrieval of objects, making it suitable for applications that require fast data access.
SPT Object Database is a Java Object Database that is built upon the Prevayler transactional object persistence framework. It aims to solve some of the significant limitations in Prevayler while leveraging its impressive features.
Firstly, an object database is a storage engine for objects, similar to how a relational database stores raw data. Several basic features are necessary for a good object database. These include persistent storage for objects and object graphs, persistence by reachability, transparent handling of references to other persisted objects, transactional semantics for object storage and management, and a query mechanism to retrieve objects. Additionally, it needs to handle indices and constraints declared on the persisted objects, managed relationships - both unidirectional and bidirectional ones - between the persistent objects, fault tolerance, simple backup and recovery processes, and an interface that is easy to use without writing lots of code.
Prevayler is a transactional object serialization open-source framework that can be implemented for other technologies. Prevayler does not work as a database; rather, it creates something similar to an object database. What makes Prevayler appealing is its high degree of fault tolerance. Sans Pareil Technologies, Inc. (SPT) was unable to cause any data corruption in the data persisted using Prevayler in numerous tests.
