NonStop Server for Java 4.2 Programmer's Reference

O
Object Management Group (OMG)
The standards body that defined CORBA.
Object Serialization
A Sun Microsystems procedure that extends the core Java Input/Output classes with support for
objects by supporting the following:
The encoding of objects, and the objects reachable from them, into a stream of bytes
❍
The complementary reconstruction of the object graph from the stream❍
Object Serialization is used for lightweight persistence and for communication by means of
sockets or RMI. The default encoding of objects protects private and transient data, and supports
the evolution of the classes. A class can implement its own external encoding and is then solely
responsible for the external format.
Object Transaction Service (OTS)
The transaction service standard adopted by the OMG and used as the model for JTS.

online transaction processing (OLTP)
A method of processing transactions in which entered transactions are immediately applied to the
database. The information in the databases is always current with the state of company and is
readily available to all users through online screens and printed reports. The transactions are
processed while the requester waits, as opposed to queued or batched transactions, which are
processed at a later time. Online transaction processing can be used for many different kinds of
business tasks, such as order processing, inventory control, accounting functions, and banking
operations.
Open Database Connectivity (ODBC)
The standard Microsoft product for accessing databases.
Open System Services (OSS)
An environment available for interactive and programmatic use with the NonStop operating
system. Processes that run in the OSS environment use the OSS API. Interactive users of the OSS
environment use the OSS shell for their command interpreter. Compare to Guardian.
