I liked how easy it was to use, even for someone with no experience in using OLTP systems! The interface could be improved by adding more icons/buttons so you don't have as many clicks required when doing something simple like creating an aggregate table or view - this would make things look much cleaner too.
Also some fields are not searchable while others do allow searching via certain parameters such as date ranges etc., which makes sense but still requires clicking through multiple options before finding what's needed sometimes. It allows us to create complex reports quickly without having access to our own servers nor needing IT support from another team member who may only work part time at most times during office hours / holidays etc.
