Should I use past tense to describe something of a permanent nature/situation?
"The Taipei 101 stands at ... (height) is the most famous financial centre in Taiwan and it has 101 floor of storeys".
Since I'm writing an essay entitled "My holiday", should I write "The Taipei 101 stood at... was the most famous financial centre in Taiwan and it had 101 floor of storeys?"
"The card access system is a fully automated system that links with... and then the data captured is..."
As I'm writing my CV, I just wonder I should use past tense to describe the system/program that I had designed, but in fact they are still existing and running at present though I had left the previous company. Would it be more consistent with the text of other tasked performed if I write
"The card access system was a fully automated system that linked with... and then the data captured was ..."
so that my whole text would be in past tense?
