P
package A collection of related classes; for example, JDBC.
persistence A property of a programming language where created objects and variables continue to exist
and retain their values between runs of the program.
portability The ability to transfer programs from one platform to another without reprogramming. A
characteristic of open systems. Portability implies use of standard programming languages,
such as C.
protocol A set of formal rules for transmitting data, especially across a network. Low-level protocols
define electrical and physical standards, bit-ordering, byte-ordering, and the transmission, error
detection, and error correction of the bit stream. High-level protocols define data formatting,
including the syntax of messages, the terminal-to-computer dialogue, character sets, sequencing
of messages, and so on.
S

• The hardware component of a computer system designed to provide services in response
to requests received from clients across a network. For example, the Neoview platform,
which provides transaction processing, database access, and other services.
• A process or program that provides services to a client. Servers are designed to receive
request messages from clients; perform the desired operations, such as database inquiries
or updates, security verifications, numerical calculations, or data routing to other computer
systems; and return reply messages to the clients.
set() method A method used to modify a data item. For example, the Connection.setAutoCommit()
method changes the transaction mode of the JDBC driver's connection to a Neoview SQL
database. Compare to get() method.
SQL context An instantiation of the SQL executor with its own environment.
