| ### 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
