Over the years, some IT Pros may remain very confident in their knowledge and experience in a technical topic. They forget that the topic is not part of their daily work or even their current position. They will hold that believe until the day they get a basic question, a question that the first chapter of an entry level book on the topic will answer. They will have absolutely no idea what the concept means, zero! That’s when they will fall from hero to zero and realize that now they only have vague ideas about the topic. Is your 5-year-old resume still good? par Mékoné Tolrom (Presse), le 1/11/2018 5:29:52 AM
You take some database administration and design classes, use those skills in a job for a couple years and move on to another job or stay on the same job where you SQL is not part of your regular work. Months after months, you will feel like you are still good at SQL. A simple question like “what a table name synonym is and why someone may want to use it?” and you have no idea what that means. It’s a simple question. You are more focus on what you are currently doing than keeping up with theatrical concepts which is reasonable. The minor downside is that the day you want to go back to that topic, you will need to brush up, brush up because you will pick it up so quickly. At least, you need to be conscious of that simple fact.
