What data analysis software function allows users to relate several files without the use of the join command?

The correct choice reflects a function of data analysis software that enables users to relate multiple files without relying on the join command. Multi-file processing allows for the handling and linkage of different datasets, making it possible to analyze data from various sources simultaneously. This is particularly important in forensic accounting and fraud examination, where data may come from disparate systems that need to be compared or aggregated for comprehensive analysis.

In this context, multi-file processing can facilitate the investigation by providing a means to look at related records across multiple files, which is essential for uncovering patterns or discrepancies that may indicate fraudulent activity. This capability enhances the efficacy of the analysis by allowing investigators to work with multiple data sources in a cohesive manner, thereby improving the overall outcome of forensic analysis.

The other options, while relevant to various aspects of data handling, do not serve the purpose of relating multiple files without a join command in the same way. For example, record selection pertains to filtering specific records based on criteria, and correlation analysis focuses on identifying relationships between variables within a single dataset. Verifying multiples of a number does not have the contextual relevance in relational data processing. Therefore, the capacity to seamlessly process multiple files stands out as a crucial function in data analysis software for fraud examination purposes.
