The 17 steps cover tasks like creating IDOC types and message types, defining logical systems and clients, setting up file ports and RFC connections, and generating, displaying, and monitoring IDOCs in LSMW.
Data flow diagrams (DFDs) are a graphical tool used to communicate system requirements and analyze system logic. DFDs focus on the flow of data between external entities, processes, and data stores. They provide an overview of what data a system processes, what transformations are performed, what data is stored, and what results are produced. DFDs contain four main elements - external entities, data flows, processes, and data stores. External entities represent sources or destinations of data outside the system, processes represent actions performed on the data, data flows show the movement of data between elements, and data stores represent data repositories. DFDs can be decomposed into multiple levels to show increasing detail.

THE SACRIFICE HOW PRO-PALESTINE PROTESTS STUDENTS ARE SACRIFICING TO CHANGE T...indexPub
The recent surge in pro-Palestine student activism has prompted significant responses from universities, ranging from negotiations and divestment commitments to increased transparency about investments in companies supporting the war on Gaza. This activism has led to the cessation of student encampments but also highlighted the substantial sacrifices made by students, including academic disruptions and personal risks. The primary drivers of these protests are poor university administration, lack of transparency, and inadequate communication between officials and students. This study examines the profound emotional, psychological, and professional impacts on students engaged in pro-Palestine protests, focusing on Generation Z's (Gen-Z) activism dynamics. This paper explores the significant sacrifices made by these students and even the professors supporting the pro-Palestine movement, with a focus on recent global movements. Through an in-depth analysis of printed and electronic media, the study examines the impacts of these sacrifices on the academic and personal lives of those involved. The paper highlights examples from various universities, demonstrating student activism's long-term and short-term effects, including disciplinary actions, social backlash, and career implications. The researchers also explore the broader implications of student sacrifices. The findings reveal that these sacrifices are driven by a profound commitment to justice and human rights, and are influenced by the increasing availability of information, peer interactions, and personal convictions. The study also discusses the broader implications of this activism, comparing it to historical precedents and assessing its potential to influence policy and public opinion. The emotional and psychological toll on student activists is significant, but their sense of purpose and community support mitigates some of these challenges. However, the researchers call for acknowledging the broader Impact of these sacrifices on the future global movement of FreePalestine.

Alternative Data Flows
Where a process can produce different data
given different conditions
We show both data flows and use the process
description to explain why they are alternatives
Tip -- alternative data flows often accompany
processes with IF statements
19. Slide 19
Your Turn
At this point in the process it is easy to lose
track of the “big picture”.
Describe the difference between data flows,
data stores, and processes.
Describe in your own words the relationship
between the DFD and the ultimate new
application being developed.

Integrating Scenario
Descriptions
DFDs generally integrate scenario
descriptions
Names of use cases become processes
Names of inputs and outputs become
data flows
Combining “small” data inputs and
outputs into a single flow
25. Slide 25
Steps in Building DFDs
Build the context diagram
Create DFD fragments for each scenario
Organize DFD fragments into level 0
Decompose level 0 DFDs as needed
Validate DFDs with user
26. Slide 26
DFD Fragment Tips
All process names must be verb phrases
Maintain organization’s viewpoint in naming
processes
Layouts often place
processes in the center
inputs from the left
outputs to the right
stores beneath the processes

31. Slide 31
Level 0 Tips
Generally move from top to bottom,
left to right
Minimize crossed lines
Iterate as needed
The DFD is often drawn many times
before it is finished, even with very
experienced systems analysts
33. Slide 33
Tips for Level 1 and Below
Sources for inputs and outputs listed at higher
level
List source and destination of data flows to
processes and stores within each DFD
Depth of DFD depends on overall system
complexity
Two processes generally don’t need lower
level
More than seven processes become overly
complex and difficult to read
38. Slide 38
1. Use cases hold functional requirements in
an easy-to-read text format
2. They make a good framework for non-
functional requirements & project details.
3. Use cases show only the Functional req’ts.
4. Design is not done only in use case units.
How should we gather
requirements? Use cases?
39. Slide 39
A use case collects related scenarios
of a user’s goal succeeding or failing
UC 4: Place an order
Main scenario:
1. User identifies the customer, item and
quantity.
2. System accepts and queues the order.
Extensions:
1a. Low credit: Customer is ‘Preferred’...
1b. Low credit & not Preferred customer: ...
2a. Low on stock: Customer accepts reduced...

What sort of a use case fits your project:
Fully Dressed, ...?
Use Case 12. Buy stocks over the web
Primary Actor: Purchaser (user) Scope: PAF
Level: user goal Precondition: User already has PAF open.
Guarantees: sufficient log information exists that PAF can detect what went wrong.
Success Guarantees: remote web site acknowledged purchase, user's portfolio updated.
Main success scenario:
1. User selects to buy stocks over the web.
2. PAF gets name of web site to use (E*Trade, Schwabb, etc.)
3. PAF opens web connection to the site, retaining control.
4. User browses and buys stock from the web site.
5. PAF intercepts responses from the web site, and updates the user's portfolio.
6. PAF shows the user the new portfolio standing.
Extensions:
2a. User wants a web site PAF does not support:
2a1. System gets new suggestion from user, with option to cancel use case.

41. Slide 41
What sort of a use case fits your project:
..., Casual, ...?
Use Case: Buy something
The Requestor initiates a request and sends it
to her or his Approver, who completes the
request for submission and sends it to the
Buyer. The Buyer finds the best vendor, initiates
PO with Vendor.
At any time prior to receiving goods, Requestor
can change or cancel the request. Canceling it
removes it from any active processing.

Summary
The Data Flow Diagram (DFD) is an essential tool
for creating formal descriptions of business
processes and data flows.
Use cases record the input, transformation, and
output of business processes.
Eliciting scenario descriptions and modeling
business processes are critically important skills
for the systems analyst to master.
