I don't have technical problem. I was just thinking the difference between arrays and SQL. I am currently learning OOP in java and C# but my employment history is based on SQL Server. So I was thinking about this subject in my head and I don't see why bother with arrays when their is SQL. So I have these questions and I was wondering if someone could be kind enough to answer them...
1) What is the difference in handling data, between arrays and SQL.
2) Am I right to believe anything arrays can do, SQL can do. And SQL is more time
efficient rather than messing around with arrays regardless what software language is used.
3) Why would a company build projects based on arrays when these days it is standard practice for a company to use SQL Server or Oracle or whatever.
