Human resource software
Are there Open Source projects dealing with human resource similar to Oracle PeopleSoft, having tools such as Code (PeopleCode), Query (PeopleSoft Query), SQR (PeopleTools 8 - PSSQR), etc. and Global Payroll module as well.
Searching Sourceforge and Freshment brought me >900 software, such as;
OrangeHRM - Human Resource Management
Compiere - HRMS
Please shed me some lights. TIA
