programming add-ons, accessing backend of HRMS

HR manager asked me to pick a good HRMS system for them to use

i have zero experience with HR systems.

one of the factors that i would look at is how "open" it is and开发者_Python百科 whether i can connect to it and run select statements on it, and whether i can program add-ons.

can you recommend to me some HR systems that allow you to do these?

the organization needs software that will accomodate about 1000 employees

We use UltiPro with about 3000 users.

There is nothing about it that cannot be extended and customized off the shelf. I have been amazed at the requests we have been able to fulfill in-house just by extending the existing instance.

Even better, none of this has interfered with any upgrades to the base.

FYI: I do not work for Ultimate Software.
