Hello, I am a part of a volunteering library and I want to add a feature to it. Its elegant member will be allowed to issue books from their home. There will be 100 members who will login into that application. I want to develop an application where all the books will be showed and can be searched by their names,categories,writers name etc etc. I think this can be done with APEX, I can work with pl/sql. I've come to know that oracle provide free workspace for apex application development.Can I use that space for free where about 100 people can login? If not, do you have any alternate idea how can I do this? We don't want to cost anything, but if there's no other way except costing something, we'll be happy to keep it as low as possible. Thanks in advance.
