  1. Lecture 4.5: AV-1 and AV-2 (Ch 3.1 and 3.2) Dr. John MacCarthy UMBC CMSC 615 Fall, 2006

  2. Agenda • AV-1 Overview and Summary Information (Overview) • AV-2 Integrated Dictionary (Overview) • Conclusions

  3. Product Definition: the AV-1 “provides executive-level summary information in a consistent form that allows quick reference an comparison among architectures. AV-1 It includes assumptions, constraints and limitations that may affect high-level decision processes involving the architecture.” Product Purpose: “[It] enable[s] the reader to select one or more architectures from among many to read in detail. … it serves as a planning guide … [and] provides summary textual information concerning the architecture.” Implementation Options Hyperlinks Briefing Text, Tables, Graphics Views Multiplicity: 1/project AV-1: Overview and Summary Information (3.1) • Product Detailed Description (Content): Critical Artifact

  4. Base Product Description (X.Y.1) and UML Representation (X.Y.2) • X.1.1 provides a description of the “reference” artifact (generally SA-based) • X.1.2 provides one or more UML artifacts that may be used as an alternative to the reference artifact • Note there is no UML equivalent to a AV-1

  5. AV-1 Data Element Definition (3.1.3) [1]

  6. AV-1 Data Element Definition (3.1.3) [2]

  7. CADM ER Diagram for the AV-1 (3.1.4)

  8. Class Exercise: Develop AV-1

  9. Product Definition: The AV-2 “contains definitions of terms used in a given architecture.” :Consists of textual definitions in he form of a glossary” “Data repository with definitions of all terms used in all products” All functions, nodes, classes, data entity, data attribute, operations, components, interfaces, etc. Product Purpose: “Provides a central repository for a given architecture’s data and metadata.” Ensures Consistency/Unity in vision Ensures Consistency between Artifacts Implementation Options: Access Database Word Document Architecting Tool Output Multiplicity: 1/project Content: Definitions of Terms used in the Architecture: Activities/Functions/Methods Input/Output/Internal Data Entities Data Attributes (including description, data type, range, units, etc.) Actors Operational Nodes Structural Elements/Mechanisms (Systems, Subsystems, Components, Interfaces, etc.) Classes Performance Metrics Etc. May also include Acronym List AV-2: Integrated Dictionary Critical Artifact

  10. Taxonomies (Types of entities)

  11. Base Product Description (3.2.1) and UML Representation (3.2.2) • 3.2.1 provides a description of the “reference” artifact (generally SA-based) • 3.2.2 provides one or more UML artifacts that may be used as an alternative to the reference artifact • Note there is no UML equivalent to a AV-1

  12. Data Element Definitions (3.2.4) and CADM Model (3.2.5) • Blah Blah Blah …

  13. AV-2: Integrated Dictionary -WBRS Example

  14. Entry Types: Operational Node (ON) Operational Element (OE) System (Sys) Subsystem Element (SE) Actor (Actor) External System (ES) External Subsystem Element (ESE) Function/Activity (Fnc) Rule Model (RM) State (State) Data Entity (DE) Data Attribute (DA) Reference ID: Function/Activity: A1.X.y System/Subsystem Element: C1.X.y External System/Subsystem Element: ESX.Y Rule Model: RM1.X.y Data Entity (DE): DEX.y Acronym Term Definitions Functions should indicate I/O Des and Rule Models System/Subsystem Elements should include alllocated Functions DEs should include list of DAs DAs should include data type, visibility, and ranges. RMs should include reference to functions and DEs Example: Integrated Dictionary Legend

  15. Conclusions • AV-1 and AV-2 are essential products for every architecture • AV-1 is usually developed in a Word (or HTML) document and may be hyperlinked to supporting artifacts • Initially one may want to develop the AV-2 in Word or Excel until you figure out the desired format or until a CASE Architecture Tool is selected.
