a) analyzing large amounts of data, such as employee pay and performance

Explanation:

An information system is a combination of components that work collectively in the storage, transfer and processing of data. Information systems have various features including data mining which is a major component. Data mining can be defined as the process which data input is converted into useful information or output. In a company situation, there is usually large blocks of data. Going through these data blocks manually can be very tedious and time-consuming , thus costly. In most organizations however, they utilize data mining to break data down into simpler information that can be understood in a short time.

Data mining works by going through large data blocks and extracting relevant trends and patterns in them. Data mining has a number of uses, namely; detection of fraud, risk management of credit, and filtering opinion of users. The steps involved include: collection of data, then the data is loaded and stored in organizational servers, then analysts organize the data, then the data is processed using a software and finally the end result is presented in an easy to understand format.

In our case, Latoya is the company's human resource information system manager, thus her data-mining will probably involve analyzing large amounts of data, such as employee pay and performance.
