Fairytale 1.
First there was chaos. Dijkstra came along and told us all to look for invariants to find structure.
Enter database. Trees were easiest, so: trees. (IMS)
Trees are semantically crippled, so: mazes. (CODASYL)
Don't hide reference information. (R2)
Fairytale 2.
IBM: let there be databases (IMS)
ANSI: good idea, let's standardize 'm.
IBM: No! It's our garden.
CODASYL: We have some nice flowers (SET, OWNER, MEMBER)
IBM: We don't care. Our flowers are much much much more beautiful - wait for us, but for now we only have pictures (vaporware a.k.a. relational theory).
