I need your help to choose my career as I have three years of gap between my education. I know SQL. Can anyone tell me should I choose MS SQL server or oracle because I am interested in the database? Which one will be better to learn to get into the IT industry? Please help me! Thank you!
As you are strong and interested in SQL, why not to choose ETL Testing? It has a good career ahead in data projects. To survive in the market, you need both Oracle & SQL Server. Actually, both are almost same but are different products.
