Introduction
By replacing the PROM model with the Doctrine ORM GOCDB will support RDBMSs other than Oracle.
Benefits
- Write code once, deploy to Oracle, MySQL, Postgres, SQLite.
- Much simpler than the GOCDB/PROM model (see below)
Changes
The move to Doctrine will introduce changes to the GOCDB portal URLs and to the PRIMARY KEY, ID and GOCDB_PORTAL_URL fields of the GOCDB PI.
Portal URLs
In PROM, each "entity" (site, service endpoint, downtime) was assigned an ID from a global pool. There is only one object 123, the GRIDOPS-GOCDB site. The following URL is used to access an entity regardless of type:
https://goc.egi.eu/portal/index.php?Page_Type=View_Object&object_id=123&grid_id=0
In Doctrine, each entity receives an ID unique only to that entity type. There is a site with ID 123, a service endpoint with ID 123 and a downtime with ID 123. The new URL will reflect the entity type:
https://goc.egi.eu/portal/index.php?Page_Type=Site&id=123
https://goc.egi.eu/portal/index.php?Page_Type=Service_Endpoint&id=123
https://goc.egi.eu/portal/index.php?Page_Type=Downtime&id=123
(...and so on for each GOCDB entity type)
