I would suggest you to look at SQL.
Why? You can sort filter what ever you want very easily. Even if for now you think you don't need it, I am sure that in a near furure you want these features.
It is not that complicated, a few years ago, I had never used a database.
Then I found the need for it looked deeper into it and found it relatively easy and asked myself: why hadn't I looked at this before?
You can have a look at the
B4X SQL Database booklet, it includes simple SQL projects.
