a visual representation of different data using conventions that describe how these data are related to each other
ER diagrams are most often associated with...
complex databases that are used in software engineering and IT
ER diagrams are frequently used during which stage of the development process in order to identify different system elements and their relationships with each other
the design stage
What are the three basic elements in an ER diagram?
1) Entity
2) Attribute
3) Relationship
What is an entity?
can be a person, place, event, or object that is relevant to a given system; represented by a reactangle
What is a weak entity?
an entity that depends on the existence of another entity; cannot be identified by its own attributes
What is an attribute?
a property, trait, or characteristic of an entity relationship or another attribute
What is a multivalued attribute?
an attribute can have more than one value
What is a derived attribute?
an attribute based on another attribute
What is a relationship?
describes how entities interact
What is a recursive relationship?
when the same entity participates more than once in a relationship
What is a business rule?
a rule that defines or constrains some aspect of business and always resolves to either true or false
What are business rules intended to do?
to assert business structure or to control or influence the behavior of the business; they describe operations, definitions and constraints that apply to an organization
What can business rules apply to?
People, processes, corporate behavior and computing systems in an organization, and are put in place to help the organization achieve its goals
Business Rules describe...
the operations, definitions, and constraints that apply to an organization
What is another name gathering business rules?
Rules harvesting or business mining
What are definitions of business terms?
the most basic element of a business rule is the language used to express it
What are facts relating terms to each other?
the nature or operating structure of an organization can be described in terms or the facts that related terms to each other
What are constraints (action assertions)?
every enterprise constrains behavior in some way, and this is closely related to constraints on what data may or may not be updated
What are derivations?
business rules define how knowledge in one form may be transformed into other knowledge, possibly in a different form
What are the business rules gathered in these situations?
1) When dictated by law
2) During the business analysis
3) As an ephemeral aid
What is a decision tree?
provides an alternative and more convenient way of viewing and managing large sets of business rule, especially when these rules are not symmetric
Decision tress provide an alternative and more convenient way of viewing and managing...
large sets of business rules, especially when these rules are not symmetric
Decision trees are easy to use once you understand that:
1) a condition is declared in its diamond shape node
2) the possible values for the condition are represented by branches
3) the actions are declared at the end of each branch
A decision tree contains a preconditions section that lets you:
1) set variables that can be used in the decision tree
2) set a condition that is applied to an entire decision tree
Decision trees are an important topic in business analyst training because...
they are essential when you find detailed logic in process flows
Decision trees
helps to see if we're missing any branches in our logic
Decision trees =
logic; not flow or order

complex ideas
What is a concept map?
graphical tool for organizing and representing knowledge
What are linking words?
words on the line that specify the relationship between the two concepts
What are propositions?
statements about some object or event in the universe, either naturally occurring or constructed
Concept maps express explicitly...
the most relevant relationships between a set of concepts
What are cross links?
Help us see how a concept in one domain of knowledge represented on the map is related to a concept in another domain shown on the map
big picture accuracy
Investigative Architecture is lightweight enough to...
quickly draft as a way to introduce stakeholders to the design
What is Systems Analysis?
the process of studying a procedure or business in order to identify its goals and purposes and create systems and procedures that will achieve them in an efficient way
