HRIS system for Performance Management in my company

After talking about Cornerstone, its features and benefits, I became more curious to find out if we have any HRIS for performance management in my company considering the fact that so far I have never had a performance review though have been with the company for about a year and 8 months and have had merit increases couple of times!
After talking to my manager, I found out that we do have an HRIS but only managers have access to it and after a quick look into the system I found out that there is a long list of measurements only 10% of which are included in the job description which really surprised me!
I found it very unfortunate that in big companies such as the ones I have worked so far,  not only HR fails to communicate to the new hires about the HRIS system, the things they can do with it and its benefits, but also the system itself is not comprehensive enough which makes it very confusing for the employees to use. In other words, they have to log into different systems to check they paycheck, enter their work hours, enroll in benefits and even like me just find about a separate HRIS system for Employee Recognition!!
