GUARANTEED SUCCESS
Time Constraint 1. Timing of processing ( ex: wire transfer must be processed by 2pm)
2. Time allotted for a process
3. External time requirements
4. Synchronous processing ( A and B must be completed, before C)
5. Response time for external interface processing
Structure Constraints the relationships between data, meta-data ( knowledge about data),
knowledge and meta -knowledge ( system generated knowledge) in applications.
DATA: CON100
META-DATA: Field=Customer-ID, Size=6, Type=xxx999,
Validation= Occurs once per customer
KNOWLEDGE: CON001 must pay cash for sales
META-KNOWLEDGE: If Customer-ID > ???050
and accounts receivable balance> 1 000
cash sales only else, OK credit sales up to 1000.
Control Constraints relate to automated maintenance of data relationships
ex: batch total must equal sum of transactions.
, Inferential Constraints limits on the reasoning ability of the application and its ability to
generate new facts from previous facts and relationships.
3 Types: human, manual, and computerized.
HUMAN: means by which an application communicates to its human users. ( most important
and difficult to design)
MANUAL: reports or other human-readable media that show information from the computer. (
paying electric, telephone bill )
AUTOMATED: data maintained on computer-readable media for use by another application.
Responsiveness how long it takes the system to act on and respond to user actions. It
reflects the fundamental design approach as batch-oriented, on-line, or real-time.
Batch Applications applications in which transactions are processed in groups. Transactions
are gathered over time and stored together. At some predefined time, the batch is closed and
processing on the complete batch is done.
Batch-> master file -> new master file -> log of processing.
Online Applications provide interactive processing with or without immediate file update.
Interactive processing: two-way dialogue between the user and the application that takes place
during the processing.
Real-Time Applications process transactions and/ or events during the actual time that the
related physical ( real world) process takes place.
