I did not have any previous experience with the Hive Application Framework (HAF) and I can say that I just started researching it. And to share my first impressions.

I think that working with data in PostgreSQL database will be much more efficient and faster for me than working on data in blockchain. And I think HAF based application will be faster. I have sufficient knowledge of MySql, Oracle, MSSql. I have no experience in PostgreSQL, but I know that I will not have any difficulties. I see that there are useful add-ons in HAF and I think they will be very useful for me. Especially in the case of a blockchain fork, the rollback action caught my attention. It is the most important issue for a programmer and database administrator. It happened to me, sometimes it can take days to fix the mistakes.

I'm currently reviewing the code for HAF on https://gitlab.syncad.com/hive/balance_tracker/-/tree/develop it will improve my coding experience on the blockchain. I haven't set up a HAF server yet, but I'm planning to setup a HAF server soon. In this way, I think that I will have the opportunity to examine the sample codes in more detail and that I can write sample codes myself. This will increase the experience.

I have developed many applications but no experience in blockchain. I'm reviewing sample codes and articles to develop my own application on the Hive blockchain. Hopefully when I feel ready I will start writing code to develop my own app.

I also believe that HAF will both make it easier for me to write code and reduce the amount of code. I don't know much about HAF at the moment, but I hope to share more experiences in the future.
