Unit 2 - Lesson 1 - Server Fundamentals 1

Question 1

List stereotyped class types in the Curam Model

Answer 1

Domain Definition
Entity
Struct
Process
Facade
and more

Question 2

Define Domain Definitions

Answer 2

Curam concept of simple application-level data type definitions
Unwind to fundamental data types
All attributes to be defined in terms of domains

Question 3

Define Struct

Answer 3

Collection of Attributes
Never has methods
Used as argument & return type for Facade, Entity & Process classes
Groups arguments to avoid long argument lists
Java class created per each struct in the model

Question 4

Define Entity

Answer 4

Associated with DB tables. Can have attributes & methods
Attributes become columns of the DB table.
Java class is generated from the Entity using:
READ
INSERT
MODIFY
REMOVE
READMULTI
will form primary keys. You can specify multiple s to form composite key

Question 5

Define Shadow Class

Answer 5

Structs that are automatically generated based on Entity class attributes
Generated structs are referred to by the shadow type:
Key, Dtls, DtlsList, KeyList

Question 6

What Shadow classes are created for specific operations

Answer 6

> , > - Key & Dtls
- Dtls
- Key
- DtlsList

Question 7

Define Process model (Business Process Object)

Answer 7

Business logic of the application
No direct association with database tables or client processing
Method signatures are modelled, method logic implemented by developers
A java class per process class
Contains calls to processes & entity methods
Not client visible

Question 8

Define Facade model

Answer 8

Client-specific logic
Not directly associated with database tables
Never has attributes
Method signatures are modelled, dev implements content
Java class per Facade class
Client-visible
Calls to processes & entities

Question 9

Curam naming conventions

Answer 9

Domain Definitions - ACCOUNT_NUMBER
Entity - BankAccount
Attribute name - accountNumber
Operation name - readAccount
Named aggregation - dtls, key, dtlsList
Process or Facade class - ProcessBankAccount

Question 10

RSA for Curam offering

Answer 10

IBM Curam profile - defines UML stereotyped elements and values can be defined within Curam model
Curam Model template - IBM Curam Profile + filtering capability to remove unnecessary or unsupported functionality from RSA

Question 11

Mapping model to code

Answer 11

Intf - public abstract
Base - protected abstract
Impl - public/protected implementation
Fact - factory.newInstance() extending Impl

Stereotyped entities’s factory will extend from base as implementation is included for free
Developers must declare implementation as abstract to enforce Factory

Question 12

Model compilations & JAR

Answer 12

build generated - model into code and compile some classes
JARs generated:
struct.jar
messages.jar
events.jar
codetable.jar
application.jar
Project class path should include above and exclude struct & intf folders
