Generalized audit software (GAS) is specifically designed to assist auditors in performing various audit tasks, including extracting specific files and records from databases. GAS tools, such as ACL and IDEA, allow auditors to import data from various systems, query databases, perform data analysis, and generate reports.
This makes them ideal for tasks that require the extraction and examination of specific records or data sets within a database. Other options, such as expert systems or system utility programs, do not offer the same targeted capabilities for data extraction relevant to auditing tasks.References:
