Generic Tool Summaries:
· LCP stands for Life Cycle Prototyping.
· BDE stands for Block Diagram Editor.
· GEN stands for database code GENerator.
Most of the projects indexed here involve
prototypes of three generic CASE tools described in the COOL slides above.
These tools have been continuously evolving for multiple languages, GUI's and
hardware platforms. They are carried out within ongoing projects of graduate OOA&D (91.522) and Software Engineering (91.523)
courses. These courses are taught by Professor Lechner
within the Computer Science Department.
GEN supplies database code libraries by which
BDE and LCP can import/export, maintain and navigate an arbitrary normalized
EERD database. (EERD denotes an entity-relational data model extended with
inheritance.) (see also gencpp below).
BDE is a generic diagram editor, whose data
model is described in the BDE slide presentation referenced above.
Historically, BDE evolved first as a C program interfaced to INGRES It ran
under Unix and used X11/Motif as its GUI. Then BDE was rewritten in C++ and was
adapted to take advantage of GEN.
LCP is a generic table-driven State Model
(SM) interpreter which simulates concurrent event-driven behavioral prototypes.
Its State-Event Model inputs represent Active Classes as in the text: [Shlaer-Mellor: Object Life Cycles, Prentice-Hall 1992].
All three tools read ASCII-text-based tables
that can be manually text-edited and converted to EERD or State-Event Model
(SM) diagrams for BDE display. However, BDE simplifies the use of GEN and LCP
because users can draw block diagrams (static information models and dynamic
behavior models) interactively and save them in a persistent relational
database as ASCII text. These tables subsume graphic layout information as well
as semantics of user-defined types.
BDE and LCP both take advantage of customized
GEN-supplied code libraries which can import/export, maintain and navigate
tables of an arbitrary normalized relational data model. A GEN-supported
database application maintains surrogate primary/foreign (p/f) keys to simplify
access. (Human readabilty is less important within
CAD/CASE tools, whose content is seldom directly read or updated by its users.)
BDE Diagram Conversion (bde2*) Projects:
To convert BDE diagrams to (and from) the
metadata formats of GEN and LCP respectively, various data conversion projects
were also implemented. Project names bde2* with prefix "bde2" have
been used for these projects:
· bde2SM and SM2bde for BDE to LCP conversion
· bde2sch = (b2t+t2s) and sch2bde = s2t+t2b for
BDE to GEN conversion.
BDE Language/Platform Conversion (bde2*) Projects:
Projects which do hardware platform and GUI
environment conversion (port the software) also use project names with prefix
bde2*:
·
bde2ht*: Conversion of BDE diagram sets to HTML
for Web browsing
·
bde2VCPP, and bde2alpha: Ports of BDE source
code to WinTel and DEC/alpha/DigitalUnix
platforms respectively.
·
bde2jav* and bde2PC: Rewrites of BDE to the Java
language and to the platform-independent wxWindows
GUI respectively.
BDE Diagram Conversion to HTMl and .gif format
for web browsing (bde2ht*):
·
Bde2ht* is a family of projects to produce
interlinked web-browsable images with hotspots at
each node of each BDE block diagram.
·
Bde2ht3 was a 95f523 project to convert a file
of block diagrams, that were generated by the Block Diagram Editor BDE, into a
set of .html, .gif and image-map files. Hyperlinks are automatically generated
to link any node of any diagram to refinements or expansions defined by other
diagrams and/or text. Each visible node in any diagram can have two clickable
hotspots defined as its upper or lower half respectively.
·
The bde2ht3 project was extended by spring 1996
projects bde2ht1 and bde2ht2. These projects update index and menu files after
new html files are produced by bde2ht3, and provide email forms to add a row to
any database table of any schema that is compatible with GEN, our database code
generator.
BDE Ports to the Java(TM) language (bde2jav*):
·
The bde2jav1 project in 96s523 and 96su591
partially completed a Java implementatiion of a BDE
block diagram browser and editor prototype, respectively. These are partly
functional and have veen extended and documented with
javaDoc. They work by down-loading a BDE diagram file
and converting it into Java classes. Java applets display the diagrams and
detect their hotspots. This avoids bde2ht3 preprocessing but expands a single bde data file to three files per diagram.
·
The first bde2Java project represented the
clickable hotspots by small pink or gray squares at the right sides of each
node; later, these were made invisible. [Project 96s523/bde2jav2 allows email
returns of the content of one row of any table when this row of a schema
diagram is selected.]
In 97s523, project bde2gif improved both the bde and
bde2java editors by adding an option to convert one or all diagrams to .gif
format. This is a prerequisite to and simplifies bde2ht* conversion, and now
both C++ and Java versions of bde can generate .gif files.
Ports of BDE to Microsoft's Visual C++ (bde2vcpp):
Several projects produced and improved this version
of BDE, which is not yet complete (and may never be, since a PIGUI is
preferable.) (PI = platform-indepenent)
Gencpp: A class-based version of chgen
(rev. 010827; URL TBD - RJL)
·
Both
chgen and gencpp support a
normalized object-relational database for complex objects, chgen's
API manages structs and functions in C, while gencpp manages corresponding classes and methods in C++.
When imported to memory-resident form, a GEN-defined database supports imbedded
pointers and O-O navigational capability.
·
A
The GEN-defined database is appropriate for handling complex transactions such
as editng a graphic CAD or OO-CASE design database.
The evolution of chgen to gencpp
will generate classes with method declarations and containers instead of
relational tables and demonstrate an evolutionary, not revolutionary, path from
RDB to ORDB and OOAD methodologies.
·
The
jury is still out about object-relational databases and their evolution. Tom Janzen critiqued an early version of gencpp;
Naiyana Tansalarak
completed the latest one, for which Kathy Miu fixed
alpha 64-bit port warnings. Similar port fixes are needed in chgen - whose bde/pr_util library
API support code was manually edited but is not yet auto-generated correctly.
