| Usergrid Services Layer |
| |
| This is where most of the high-level functionality for accessing Usergrid data |
| is performed. It functions as the glue between the REST API as exposed by |
| Jersey and the entity management functionality in usergrid-core. This is also |
| where security and account management functionality is contained. |
| |
| The security model of Usergrid is implemented with Apache Shiro: |
| |
| http://shiro.apache.org/ |
| |
| The services model for Usergrid involves converting the REST web service |
| requests into collection queries and routing these to a set of collection |
| handlers. This provides a "virtual collection" layer on top of the actual |
| collections that are exposed in the persistence tier. This makes it possible |
| to: |
| - implement logic behavior on top of persistent objects |
| - enforce object and property visibility |
| - perform fine-grained permission checks |
