Design the bridges

The scenarios illustrated here show some conventional and some unconventional design alternatives. This is not a comprehensive set of alternatives; the goal is to illustrate alternatives that may not be obvious to you yet may be useful in solving particular year 2000 problems.

These scenarios emphasize the importance of application architecture.

The unconventional alternatives may be practical only under special circumstances.

Click to see each scenario:

Separate conversion, scrubbing, & bridging program

Single bridge program

Error-thru vs. error-end

Conversion of original data store in a series

Incremental data conversion

Conversion of only recent GDG generations

Replication of date fields

Access-driven data conversion

Common I/O for core data stores
