As an AI language model, I don't have access to any particular database or source of information. However, I can provide you with a sample JSON format of IQ levels of the roles you mentioned: ``` { "data_analyst":{ "iq_low":90, "iq_average":110, "iq_high":130 }, "data_architect":{ "iq_low":95, "iq_average":115, "iq_high":135 }, "data_scientist":{ "iq_low":100, "iq_average":120, "iq_high":140 }, "sysadmin":{ "iq_low":85, "iq_average":105, "iq_high":125 }, "database_expert":{ "iq_low":90, "iq_average":110, "iq_high":130 } } ``` This is just an example and the IQ levels are not based on any scientific research or data analysis. These levels are also dependent on various factors such as education, experience, and training.
