A multiple segment data structure and method manage data objects stored in
multiple segments. The structure and method use one or more multiple
segment index table objects containing defining information about the
data objects in which the data are stored, such as the state, index table
size, and one or more index tables referencing the data segment objects.
The data objects themselves comprise a header, specifying information
about the data segment, including a data segment state, and a data
section in which data actually are stored. The state fields in the index
table object and the data segment objects facilitate the data recovery
process.
