DOMAIN-DRIVEN DESIGN (DDD)
Domain-driven design is a concept that the structure and language of
software code should match the business domain.
● Eases communication
● Improves flexibility
● Emphasizes domain over interface
● Requires robust domain expertise
● Encourages iterative practices
● Ill-suited for highly technical projects

AUTOMATION OF WORKFLOWS
7
SERVERLESS WORKFLOW
8
● Similar specification to BPMN but aimed more
at developers
● More lightweight, no human tasks, targeted at
machine interaction
● Workflow is “modelled” directly by writing the
code (JSON/YAML), currently doesn’t define
graphical notation
● Higher level than BPM, focuses more on
orchestration of services or infrastructure in
the cloud, self-healing infrastructure
● Background service, end users don’t interact
directly with it (as with BPM in loan approval,
order processing…)
● https://serverlessworkflow.io/
● BPMN vs. SWF

AUTOMATION OF LONG-LIVED TRANSACTIONS
11
Saga pattern for microservice architectures
If any microservice fails to complete its local
transaction, the other microservices will run
compensation transactions to rollback the changes.
Advantages
● support for long-lived transactions
● other microservices are not blocked if a
microservice is running for a long time
● there is no lock on any object
Disadvantages
● difficult to debug
● difficult to maintain if the system gets complex
● does not have read isolation
Adding a process manager addresses the complexity
issue of the Saga pattern when it becomes responsible
for listening to events and triggering endpoints.

AUTOMATION OF BUSINESS RULES
14
Kogito DRL Rules language
Policy
"change customers in the Gold category to the Platinum
category when they spend more than $1,500 in a single
transaction"
Action Rule
If All of the following conditions are true:
- the customer category is Gold
- the value of the shopping cart is more than $ 1,500
Then Change the customer category to Platinum
IBM Action rules express business
policy statements using a
predefined business vocabulary
that can be interpreted by a
computer.
AUTOMATION OF DECISION TABLES
15
Types of decisions
● Selection (routing)
● Scoring
● Categorizing
The decision doesn't take an action
(no side effect), just determines a
data value

}
/* = Expected output data = */
"Fine": {
"Points": 7,
"Amount": 1000
}

AUTOMATION OF SCORING
20
Scorecard is a risk management tool used mostly by banks to calculate
the risk they take by selling you one of their products.
How risky is a customer?
What are the changes the customer might default on payment?
Based on the customer score we may adapt the product offer - a better
interest rate, a higher credit limit, etc.

conversations with users via text messages on chat
or text-to-speech.
