TITLE IBM DATAATLAS FOR OS/2 VERSION 1.0
ABSTRACT Feel like you've lost control of your organization's growing
application development and database environment? The IBM DataAtlas
for OS/2 (R) enables you to regain control over your company's
metadata, the information you rely on every day to accurately
describe your organization's data and applications.
IBM DataAtlas for OS/2 has rich functionality to handle a wide
range of databases and languages for the development of new
applications and the maintenance of existing applications.
DataAtlas handles your relational and hierarchical database
definitions for IBM's premier MVS and OS/2 databases: DB2 (R) for
MVS, DB2 for OS/2 (DB2/2 (TM)), and IMS DB. Support will also be
provided for Oracle** and Sybase**.
It handles your high-level language data definitions for
VisualGen (TM), COBOL, and PL/I. It can also scan your JCL libraries
to assist you in documenting your application systems.
DataAtlas participates in the IBM VisualGen Team Suite. The
VisualGen Team Suite is an advanced, integrated, LAN-based
development environment for mission-critical transaction processing
applications. This suite provides visual programming, 4GL
development and testing, conceptual data modeling, and database
design, along with the data administration facilities of DataAtlas.
These facilities are tightly integrated and managed by the
TeamConnection component, a robust, LAN-based, object oriented
repository incorporating a software configuration manager (SCM).
With this solution, you can quickly develop the application
with a powerful visual programming/code generation tool, VisualGen,
find and include the data that is needed via DataAtlas, test, and do
an automated build and package via the TeamConnection. All this can
be done within this tightly integrated solution.
DataAtlas, through TeamConnection, provides facilities for
versioning, model extensibility, constraint specification and
checking, and a SQL query capability all built upon a LAN-based
object-oriented database.
IBM intends to make DataAtlas available in Fourth quarter 1994
as a part of the VisualGen Team Suite to a selected set of customers.
These customers are participating in a beta evaluation and test,
providing feedback on product function and quality. When these
customers confirm that IBM has achieved the functional and quality
objectives, IBM then plans to announce availability and detailed
information regarding pricing and ordering.

DataAtlas:
o Provides a state-of-the-art OS/2 Presentation Manager (R) object
oriented graphical user interface (GUI) with an integrated
tutorial
o Participates in IBM VisualGen Team Suite
o Utilizes the versioning, model extensibility, constraint
specification and checking, and SQL query capability of
TeamConnection
OVERVIEW DESCRIPTION
Like its forerunners, the OS/VS DB/DC Data Dictionary and IBM
Dictionary Services/MVS, DataAtlas provides a central point of
control and standardization for the data definitions of relational
databases, hierarchical databases, and high-level languages. The
support plan includes:
o DB2
o DB2/2
o IMS/ESA DB
o Oracle
o Sybase
o COBOL
o PL/I
Application programmers and database administrators can use
the IBM DataAtlas for OS/2 to:
o Populate the DataAtlas with data definitions from the production
environment. DataAtlas provides scanning functions that can take
existing data structures like catalogs and copybooks and use them
to populate the common model in the datastore. For example,
DataAtlas uses DBD (database descriptor) and PSB (program
specification block) information from IMS load libraries to
populate the model.
o Create new data definitions. This can be done via a template
dialog that DataAtlas provides.
DATA BASE : ALET PAGE: 3
o Maintain existing data definitions. DataAtlas dialogs enable
authorized users to add, update, and/or delete these data
definitions.
o Perform impact analysis. DataAtlas allows various "canned" or
custom queries to be run against applications or data to
understand the relationships between, and the effects of changes
on, the application parts and the data parts. The reports on the
query results can be printed for further analysis.
o Validate data definitions prior to generating them. For example,
DataAtlas provides functions to validate IMS DBDs and PSBs in
terms of their macro syntax.
o Generate data definitions back to the production environment.
DataAtlas provides functions to generate DBDGEN and PSBGEN source
statements for IMS from definitions stored in the common model in
the datastore. Similar support exists for generating relational
data structures (including DB2, DB2/2, Oracle, and Sybase) as
well as COBOL COPYBOOKs and PL/I DECLAREs.
In addition, DataAtlas provides application system functions
that can assist in the documentation of all source module
relationships. This can help provide information on how
applications, jobs, and programs are related to one another. To do
this, DataAtlas scans JCL libraries, downloads the needed data to the
workstation, and populates its datastore.
DataAtlas also provides a migration tool to move information
from the OS/VS DB/DC Data Dictionary.
PRODUCT POSITIONING
Like other dictionaries, DataAtlas provides the single point
of control to populate, create, maintain, and generate data
definitions.
However, DataAtlas has advantages in several areas. From a
usability standpoint, DataAtlas has a state-of-the-art
OS/2 Presentation Manager object oriented graphical user interface
(GUI) with an integrated tutorial that makes learning and using its
function easier and faster.
Further, the datastore of DataAtlas has advantages. This
platform provides a comprehensive configuration and versioning
mechanism capable of common maintenance and tracking of all
definitional aspects of an application, both data and program. The
underlying object-oriented, client-server object database provides
good performance for the complex associations supported by the
platform. The client-server platform of DataAtlas has the advantage
of providing good performance for its GUI interface while exploiting
the processing power of today's desktop machines.
In addition, DataAtlas, which may be ordered as a separate
product, is also available as an integrated part of IBM's VisualGen
Team Suite. DataAtlas shares a common model with IBM's advanced 4GL,
VisualGen, as well as the repository and library functions of the
prerequisite platform product, TeamConnection. The power of this
integrated solution to rapidly and easily build, update, and maintain
applications is an important reason for considering DataAtlas.
Complementary to DataAtlas, IBM offers DataGuide (TM), a
business-oriented tool supporting end users in locating and accessing
DATA BASE : ALET PAGE: 4
data. DataGuide can help the end users access information and data
via decision support tools.
DataAtlas and DataGuide have complementary roles in the life
cycle of metadata. The metadata in DataAtlas, created to support
database administration and application development, is an excellent
source of information for DataGuide as the database schemas and
applications are placed in production.
STATEMENT OF DIRECTION
To take advantage of the metadata available in DataAtlas, a function
will be provided in a future release of DataGuide to allow data
descriptions from DataAtlas to be imported into DataGuide.
SERVICES
The four modules in the DataAtlas services offering cover:
o Data modeling
o Data design
o Data migration
o Data administration
