Tell me more about the key result (report optimization)

The key result "report optimization" in the context of Go development can mean improving performance and ease of working with reports, for example, in business logic or analytics.

This may include:

• Reducing report generation time through optimization of algorithms and database queries.
• Decreasing memory and resource consumption when processing large volumes of data.
• Improving readability and structure of the code responsible for report formation.
• Automating and standardizing output formats (JSON, CSV, PDF).

Example: if a report is built based on a database query, you can use the database/sql package with prepared statements and efficient pagination, and for formatting — packages like encoding/csv or text/template.

rows, err := db.Query("SELECT id, name, value FROM reports WHERE date >= ?", startDate)
if err != nil {
    // error handling
}

// Processing and forming the report

Report optimization is a set of measures aimed at increasing efficiency and quality of data handling in the application.
