Sessions – wednesday: Model vs. code



Not all concepts are best communicated with
diagrams
code often fails to express the big picture
guidelines for combining rapid prototyping and
formal design into an efficient development process.
– Software archeology: discovering the structure



Modeling = communication
Modeling vs. code -> Picture books vs. written word
Iteration: design-develop-design-develop-...

No need for Home- Remote- ...all in one.
Sessions Wednesday: Getting the Most Out of
MIDP 2.0 Security and Networking

Security risks







DW schemas: star / snowflake
Entitybeans useful: read-only Entitybeans make an
excellent clustered cache!
EntityBean design differs in DW application
BMP usage faster than CMP in this app: from
seconds to parts of second
JDBC ca 10% faster in bulk inserts than CMP
Use optimistic concurrency & high isolation level
Use surrogate keys - > changes in structure won’t
break the design
