Use of Aliases in Tabular Expressions
Experience has shown that tabular expressions can improve the readability of
document for conditional function and relation which frequently occur in
software documentation, but tabular expressions may still be long and hard
to read when the same substructure of a complicated data structure appears
in several places in tabular expressions. Parnas proposed the use of aliases
to reduce the complexity of tabular expressions. An alias is a short
identifier that designates a substructure or a set of substructures.
Once an alias is defined, the short identifier can be used in tabular
expressions. This thesis presents how to define aliases and how to use
aliases in tabular expressions. This thesis also shows that the use of
aliases can improve the readability of tabular expression. Tabular
expressions containing aliases can be evaluated using the Alias Table
Tool and the Code Generator. The Alias Table Tool, which works as a
preprocessor of the Code Generator, has been developed.
