I like how easy it was for me (a non programmer)to learn this software because there are many tutorials available online that help you through every step with ease! If someone has no prior experience using MS Access or any other database program then they will have an easier time learning protegae than something else out their such at Oracle databases etc..
Once your familiarised yourself enough wtih working within one table can be confusing when adding new rows but thats easily solved once again just follow some guides i found via Google which helped immensely!! Nothing really dislike its great tool if used correctly :).
