I'll be given employment offer by an IT company, and was requested to "take a look atInch PL/SQL since i have did not cash knowledge about databases. I've a comprehensive background in C++ among other programming languages, and so i don't believe this can pose an excessive amount of challenging. However, I do not get access to any Oracle database in your own home, so I'm wondering if there's a "toy" database and terminal online where I'm able to practice.
I recommend a greater priority is always to discover the Relational type of data, then SQL.
If you do not begin with a good knowledge of the RM, you are more prone to often use procedural solutions in which a set-based approach is much better.
