What is an OOSEEOOSEE?

An OO SwEng Environment isan integrated development environment (IDE) or framework, whose purpose is to provide automated support for an object-oriented approach to software engineering.


What is MDD?

Model-Driven Development (MDD) implies [semi-]automatic code generation from (partly graphic) models for static structure and dynamic behavior.

This is the focus of OMG’s Model Driven Architecture (MDA) and Microsoft’s Software Factory (MSSF)


What is COOL?What is COOL?

COOL (Object-oriented CASE Lab)is UML’s own home-grown OOSEE.

COOL currently consists of:•BDE, block diagram editor(s)

(evolves in 91.523 SwEng classes)•LCP, life cycle prototyper(s)

(evolves in 91.522 OOA&D classes)•GEN, database API generator(s)

(Used by all yy{f/s}{522/523} projects).COOL uses CVS* for version control._____

What is BDE?What is BDE?BDE, a generic editor for block diagrams,

is COOL’s primary design capture tool.

Current convertible diagram styles include:

•Data Structure Diagrams (DSDs) (DSD’s define EERA data models for

the static structure of GEN databases)

•Program Structure Chart Diagrams (SCDs are annotated program call trees)

•State Transition Diagrams (STDs) (STD’s define event-driven State Models

for dynamic behavior of LCP classes)


BDE Features-1BDE Features-1

• Draw nodes of various shapes

• Attach text to diagrams or nodes

• Connect nodes by edges or links

• Move or resize nodes or captions

• Attach labels to inter-node links

• Recompute node-link intersections

• Use only one button of mouse

• Annotate diagrams with captions


BDE Features-2BDE Features-2

•Store multiple diagrams in a file

•Save diagrams as .PS and .GIF

•Capture semantics for COOL use

•Capture and replay mouse events*

•Capture and replay VMNetDB updates*_____*Capture and replay via bdelog/genlog (genv12+)


BDE Status - 05su523BDE Status - 05su523• Chgenv13 at $CASE/gen/ver_13 supports bde on 2

$HOSTTYPE platforms under 2 versions of generated code pr_util_[no]log (4 bde executables from same bde/src code).

• The bde repository at CVSROOT = $CASE/95s523/95sbde/base/Master

has the latest version tagged bde050823.

• My sandbox for bde bugfixes is ~lechner/bde2alpha_rl/sandbox/bdeNT050526/bdegen13/bde

• Conditional code for log and replay have been merged into bde and into chgenv13.

• Further testing and bug fixing is TBD.

• TBD: Migrate bde to Fox/OpenGL (platform-independent)..

• The bde2java project is is incomplete and not up to date. Repository: CVSROOT = $CASE/96s523/bde2jav1/base/Master

• Bde2pc was based on $CASE/wxWindows 1.65; not in CVS; it is deprecated because it is incomplete, slow and obsolete.


What is GEN?What is GEN?A pair of programs (chgen, gencpp) which generate data-compatible C or C++ code to manage design databases for COOL and persistent data for arbitrary applications:chgen:

•generic database ‘C’ code generatorgencpp:

• generic database C++ code generator.

chgen and gencpp support normalized EERA* data models in schema files and compatible persistent database formats.

EERA = Entity/Relation/Attribute data model, extended with multiple inheritance.


CHGEN External ViewCHGEN External View

• Generic database code generator• Manages a persistent ASCII database • Based on EERA data model • Reads DB definition in schema.sch• Emits schema.h and pr_*.c files

• Used in BDE, LCP and applications______*EERA = Entity-Relation-Attribute Data Model,

Extended with 1:M genspec or inheritance relations,associating each superclass instance to one instanceof one or more subclasses.


GENCPP External ViewGENCPP External View

• Database code generator that represents all table rows as C++ class instances.

• Alternate API for chgen-style database management code.

• Options provide either STL Containers or chgen-style linked lists (but not both).

• Chgen-compatible external format.

• Chgen-equivalent database schema.


CHGEN generates API utilities which:• Compile and link to an application• Load/unload a persistent database• Convert between

•external ASCII database content•internally linked VMNetDB*

• Access and navigate resident DB.• Optionally generates code to log

and/or replay DB changes (genv11+)

CHGEN InternalsCHGEN Internals

______ *VMNetDB = Virtual-Memory-resident Network DB with 1-to-many linked lists, N-ary associations, and surrogate primary and foreign keys.


Chgen’s input is a schema.sch file that declares an ExtendedER Data model (a subset of UML Class Diagrams)

• With a schema.sch file argument, chgen generates source files pr_*.c and schema.h.

• Without this argument, chgen gives a list of optional arguments.*

• Options are defined in chgen’s User Manual.**

_________* See next slide – how to invoke chgen** -nobp, -ansi were the non-default options before genv13.

What is bde2sch?What is bde2sch?• A database schema defines record types or classes

together with implied tables or container classes which hold instances of these records or objects.

• If an EERA diagram is saved from bde, bde2sch will convert it into schema.sch format for chgen/gencpp.

• Bde2sch is a tandem combination of b2t and t2s.Its intermediate result t is a pair of tables TT and TA.TT and TA are generated by chgen –metafile.

• Bde Work-around: The schema.sch file may also be prepared manually using a text editor.

CVS repository(includes Source code)

(CVS = Concurrent Version Control System)

(CVS manages a repository of source code and documentation.)


What is CVS?What is CVS?CVS = Concurrent Version System

is a wrapper around RCS.*

CVS supports:• Multiple versions of ASCII files • Optimistic concurrency control• Multiple checkouts of the same file • File version compression via diff• Merging of non-overlapping changes

CVS update detects, and concurrent users resolve, conflicting changes._______* RCS = Revision Control System
