What is the primary requirement when creating a new data set?

When creating a new data set in FortiAnalyzer, the primary requirement is an SQL select query. This SQL select query serves as the means to specify exactly which data you want to retrieve from the database. It allows users to define the criteria and filters, such as specific time ranges, log types, or devices, ensuring that the data set reflects the specific information needed for analysis and reporting.

The SQL select query acts as the foundation for the all subsequent operations within the data set, such as filtering, grouping, or performing further analyses. Without a well-defined SQL query, it would not be possible to accurately extract and analyze the data required by administrators or analysts.

The other options, while related to the process of data handling, are not the primary requirements for data set creation. The data aggregation method, database connection string, and file export format are relevant to the data manipulation and output stages but do not fundamentally serve as the starting point for defining a new data set.
