DAFUI

Data And Function Union Interface

DAFUI

• Change flat file formats with no coding • Eliminates or minimizes programming tasks• Shorter time to market with less development

time, reduced coding, and fewer testing cycles• Reduces resources, time to completion, and

costs

DAFUI CHARACTERISTICS

• Character based data routing / manipulation is not limited to fields

• Fields can be redefined dynamically with no programming structure changes

• Buffer overruns are virtually impossible• Create DB-like views of flat data through a

graphical interface

Why it is easy

• Input to output mapping done using pictures• Data is associated with editing and processing

functions pictorially• Better accuracy can be assured by using actual

data records to map interfaces• Portable to 99% of hardware and software

platforms• No databases need to be set up or managed

Why it is easy

• No special operating system or special environment required

• Easy and fast learning curve – interfaces can be specified in your favorite editor and saved as a generic text file (no need to learn a new environment )

Legacy MethodDefine Input: ( abbreviated )inFirstName Pic X(10).inLastName Pic X(12).inAcctNumber Pic X(12).inDateMM Pic X(2).inDateDD Pic X(2).inDateYYYY Pic X(4).inAmount Pic X(11).inPhnNum Pic X(7).inAddress Pic X(24).

Move inFirstName of input to output of outFirstName Move inLastName of input to output of outLastName Move inAcctNumber of input to output of outAcctNumber Move inDateMM of input to output of outAcctNumber Move inDateDD of input to output of outDateDD Move inDateYYYY of input to output of outDateYYYY Move inAmount of input to output of outAmount Move inPhnNum of input to output of outPhnNumBlah BlahBlah etc

Define Output: ( abbreviated )outAddress Pic X(15).outLastName Pic X(14).outFirstName Pic X(18).outAmount Pic X(11).outAcctNumber Pic X(12).outDateYYYY Pic X(4).outDateMM Pic X(2).outDateDD Pic X(2).outPhnNum Pic X(7).

Legacy Method, Continued

• Write the program to move fields from the input to the output. Ex: Move inFirstName to outFirstName. (for each field)

• Compile the program, Bind, link, etc.• Move the object to testing area• Test it – format correct? , if not, go back and

start over.• Really ! ?

Done !

• Easily adjustable. No re-coding, no compiling: faster, cheaper, less risk, short time to market

What else can be accomplished?

• You just observed the most simple function available in DAFUI technology. It can do much more.

• Multiple output files can be specified, each in its’ own format.

• Multiple input files can be joined using a common key field.
