What type of join should a Data Analyst use when combining EmployeeInfo and DepartmentInfo tables to include all records from EmployeeInfo?

Using a left join is the appropriate choice when the goal is to include all records from the EmployeeInfo table while also incorporating matches from the DepartmentInfo table. A left join ensures that every record from the left table (EmployeeInfo in this case) is retained in the result set, even if there are no corresponding matches found in the right table (DepartmentInfo). If there are records in EmployeeInfo that do not have a corresponding match in DepartmentInfo, those records will still be included in the output, and any unmatched DepartmentInfo fields will be filled with null values.

This method is particularly useful when you want to maintain the complete list of employees while still being able to access related departmental information whenever available. Alternatively, other types of joins like inner join or right join would not fulfill this requirement, as they would either exclude non-matching records or focus on including records from the right table instead. A full outer join would provide a complete view of both tables but is not necessary to meet the specific requirement of retaining all EmployeeInfo records.
