1. HR Technical Architecture1

2. Technical Architecture - Summary
The Oracle R12 (HR), Oracle Learning Management (OLM), Payroll, and Labour Distribution (LD) modules are heavily tailored to Imperial College’s specific requirements
HR module is heavily customised and integral to the operation of a number of systems both within Oracle EBS (GL reporting and Purchase to Pay (P2P) procurement and expenses approvals) and external College Systems (SACS) and reporting entities (HMRS / HESA)
OLM, Payroll and LD modules are customised to some extent
Core module for which many sub systems rely upon as a single source of truth
Sub systems such as SoV (identity management) use a combination of data from HR and other college systems to check the integrity of data that we hold and to control aspects of the college’s BAU activities
All college employees have access to one or more HR responsibilities
Small number of administrative users but very large user base (external applicants)
1029 custom components incorporating customisations of functions, forms, programs
24 interfaces to non Oracle EBS systems (21 internal and 3 external)
GDPR issue (May 2018) – we are holding 17 years of historical personal data
Support of Oracle EBS R is due to end in 2021 (extended support available post 2021 but limited in terms of patch releases as no longer supported by Oracle so doing nothing really isn’t an option)
If we upgrade to version 12.2.x support from Oracle to end in 2023 so this can only be viewed as a medium term solution
