title: When to use an array vs database
body: <p>I'm a student and starting to relearn again the basics of programming. </p>
  
  <p>The problem I stated above starts when I have read some Facebook posts that most of the programmers use arrays in their application and arrays are useful. And I started to realize that I never use arrays in my program.</p>
  
  <p>I read some books but they only show the syntax of array and didn't discuss on when to apply them in creating real world applications. I tried to research this on the Internet but I cannot find any. Do you guys have circumstance when you use arrays. Can you please share it to me so I can have an idea.</p>
  
  <p>Also, to clear my doubts can you please explain to me why arrays are good to store information because database can also store information. When is the right time for me to use database and arrays?</p>
  
  <p>I hope to get a clear answer because I have one remaining semester before the internship and I want to clear my head on this. I do not include any specific programming language because I know most of the programming language have arrays.</p>
  
  <p>I hope to get an answer that can I can easily understand.</p>
