Hello Excel is good for an especific purpose. But being an expert hammer man doesn makes all the problems nails. Excel is just a tool as SQL it is just a regular tool. Nothing less nothing more. And they have their proper usage and their abuses as well. Excel proper usage is for simple data exploration and dive. Use it for anything else and its usability starts to crumble. Both in machine and people terms. Is not only that your solution will not grow well. It will be difficult to maintain and keep it floating. It going to be expensive because excel main aim is to make it easy for you to explore your two dimensional data; it doesn provides you with data structures other systems interfaces or performance. It confundes the data representation with the inner live of the data. It going to be a big fat mess! SQL any engine in the other hand is a full blown database relational system. Which means it will not only keep your data in order it will make it easy to interrelate it and mix it. Besides your image of SQL is a table and functions. Which makes it pretty easy to think this is equal to excel. But there end all possible similarities. A database counts with optimization systems like materialized views indexes several levels of interops with many different techs and is the core of any modernputer system. To use SQL is to build the foundations for a future analytics system that will overgrowth it current size. Is like putting the steel structure for the building of data you are foreseeing to make. To use Excel is to keep yourself toying with legos and pretend you can build the empire state with them. Answer will be Yes you can. Technically you can. Now try and go for the rooftop if you dare. My two cents. twitter hernanemartinez
