MacA&D Delivers Enhanced Data Models
Model Based SQL Code Generation for RDBMS Products

Placitas, NM – September 18, 2000 – Excel Software today dramatically
extended the data modeling and SQL code generation capabilities in its
popular MacA&D modeling tool. Database designers can quickly create logical
and physical data models and generate the SQL schema code for popular RDBMS
products including Oracle, SQL Server, DB2, Sybase, Informix and InterBase.
Rich data models can represent tables, views, constraints, assertions,
triggers, indexes, procedures and other SQL elements. Other general
enhancements included diagram scaling from 25% to 100%, increased
dictionary capacity and a convenient Notes window for attaching notes to
diagram objects in any type of model.

MacA&D is a comprehensive tool for system analysis, requirement
specifications, software design and code generation. Popular modeling
notations and supported methods include object-oriented analysis and design
with UML or structured analysis and design using Yourdon/DeMarco.
Information Engineering (Martin) style data models are used to develop
information systems. Model editors are complimented with verification and
balancing reports, code generation, reengineering capabilities and
scriptable HTML reporting features.

Logical data models often use expressive names and various presentation
options to communicate information between developers. The names of
database objects like tables, views and columns are typically more
constrained and cryptic in physical data models due to the RDBMS
limitations and the legacy systems that they represent. MacA&D allows
designers to easily toggle between logical and physical models and show
entities (tables) with full attribute lists, primary and foreign keys only
or customized to show specific attributes.

MacA&D’s namespace concept now supports data modeling, SQL code generation
and reengineering of different database schemas. Namespaces simplify team
development, enable powerful organizational and reporting tools, partition
complex systems and map design elements to specific SQL schemas.

Generated SQL can be customized to include primary, foreign and alternate
key constraints and check constraints in either CREATE TABLE or ALTER TABLE
statements. Other SQL elements can selectively generate DROP or CREATE
statements and RDBMS specific triggers, procedures, functions and methods.

MacA&D runs on MacOS 7.0 or later. It comes in four product editions;
Standard $495, Desktop $1295, Educational $845 and Developer $1995. Data
models created in earlier versions are automatically converted to use the
enhanced data modeling features in the Desktop, Educational and Developer
editions. Contact Excel Software for site license and upgrade prices or
