What is a segment?
A segment is a label that points to one or more database devices. Segment names are used in create table and create index commands to place tables or indexes on specific database devices. Using segments can improve Adaptive Server performance and give the System Administrator or Database Owner increased control over the placement, size, and space usage of database objects. You create segments within a database to describe the database devices that are allocated to the database. Each Adaptive Server database can contain up to 32 segments, including the system-defined segments (see “System-defined segments”). Before assigning segment names, you must initialize the database devices with disk init and then make them available to the database with create database or alter database.
When you search through your subscribers, you do so using various search criteria. A “segment” is a set of search criteria that has been saved for later use. Segments are useful for searches that you frequently perform, and for sending broadcast messages to groups of people within a given list in your account.
A. Segment is the term we use to describe the number of boat uses available throughout the day. Industry data suggests boat owners on average use their boat for a maximum of 6.5-hours per use. Over a 24-hour period, we have created three segments; morning, daytime and an evening segment. By dividing the day into three segments, we are able to provide the maximum usage of the boat to our members.
