MySQL licenses for dummies

The following summary shows my personal understanding of MySQL 5.1 licenses, packages and products. It does not necessarily reflect 100% the way MySQL understands it. But after all the discussions I hope it is as close as possible to the reality:

MySQL Embedded Database Server

(Download -> OEM Software)

 Classic  (OEM license, -MEM -InnoDB)
 Pro      (= Classic +InnoDB)
 Advanced (= Pro +Partitioning)

MySQL Community Sever

(Download -> Download)

 Community (GPL, -NDB)

MySQL Enterprise Server

(Download -> Enterprise Software)

 Pro      (GPL or commercial, -NDB +InnoDB +MEM, Basic + Silver customer, MRU + QSP)
 Advanced (= Pro +Partitioning, Gold + Platinum customer)

MySQL Cluster

(Download)

 Community Edition (GPL, all features)
 Com (ex CGE?)     (OEM or commercial, -InnoDB +NDB)
 Com-Pro           (Com, all features)
 Standard Edition  (= Com, -NDB-API -Cluster-Repl, -LDAP)

Upgrade

EP customer should follow the QSP trail unless it is critical for them to install an MRU to get a quick bugfix to hold them over until the next QSP is released.
