BACKGROUND

WHY WAS VERSION CONTROL AN ISSUE FOR INERGY?
MOVEMENT OF DEVELOPERS THROUGH THE COMPANY LEFT A
POOR RECORD OF CHANGES TO CODE
AUDITING OF CODE PROMOTION FROM DEVELOPEMNT TO
PRODUCTION WAS NOT POSSIBLE
INEFFECTIVE TO ROLL BACK FROM CHANGES IN CODE OR
DATABASES
UNEXPECTED ISSUES WITH INCORRECT CODE BEING
COMPILED DURING UPGRADE FROM eB TO eB2.1
INCONSISTENCIES BETWEEN CODE COMPILED IN
DIFFERENT LANGUAGES

VERSION CONTROL OPTIONS

12/5/2020

LOCAL (SERVER BASED LINUX)
SOURCE CODE CONTROL SYSTEM (SCCS)
REVISION CONTROL SYSTEM (RCS)
DISTRIBUTED (INDIVIDUAL REPOSITORIES WITH SYNC
CAPABILITIES)
AEGIS
MERCURIAL
CLIENT-SERVER (CLIENT LOGIN TO SERVER
APPLICATION)
VISUAL SOURCESAFE
ROUNDTABLE

LOCAL VERSION CONTROL

12/5/2020

SOURCE CODE CONTROL SYSTEM
Based on interleaved deltas, can construct
versions as arbitrary sets of revisions.
Cumbersome and not interface driven
No database control
REVISION CONTROL SYSTEM (RCS)
Features separate backward deltas for faster
access to the trunk tip compared to SCCS and an
improved user interface, at the cost of slow
branch tip access and missing support for
included/excluded deltas.
Still no interface or database control

DISTRIBUTED VERSION CONTROL

12/5/2020

AEGIS
Supports a strongly test-driven development
workflow on top of any number of different
underlying revision control systems, such as RCS
or SCCS.
MERCURIAL
Features separate backward deltas for faster
access to the trunk tip compared to SCCS and an
improved user interface, at the cost of slow
branch tip access and missing support for
included/excluded deltas.
Still no interface or database control

CLIENT-SERVER VERSION CONTROL

12/5/2020

VISUAL SOURCESAFE
Microsoft product that allows for flexibility
to control all files types.
No database control.
Pricey for what you get.
No longer distributed by Microsoft.
ROUNDTABLE (TUGBOAT)
Control of code of all types.
Progress based, so code can be compiled and used
right from application.
Database control is excellent.
Character and GUI options (though character is to
be retired).
Very reasonably priced.
Selected as the software control application.

DEVELOPMENT STRATEGY

12/5/2020
DEVELOPMENT PROCESS FLOW
TEST
DEVELOPMENT
PRODUCTION
- Least Stable Environment - Newest
Codebase -Unit Testing - Poor Data - Highest Rate
of Change
- Moderately Stable - Regression Testing - System
Flowthrough Testing - Good Data - Slower Rate of
Change
- Very Stable - Stress Testing - Live Testing -
Real-World Data - Scheduled Changes

ENVIRONMENT SETUP

12/5/2020

EXISTING SYTEM WAS TEST AND PRODUCTION ONLY
NEW SERVER BUILT AS A DEVELOPMENT SERVER
DEVELOPMENT SERVER WAS A COPY OF PRODUCTION
ROUNDTABLE APPLICATION LOADED ON DEVELOPMENT
ROUNDTABLE DATABASE CREATED ON THE PRODUCTION
ENVIRONMENT FOR BACKUP AND LOAD PURPOSES
SETUP A DEVELOPMENT USER (RTBDEV) AND AN
ADMINISTRATION USER (RTBADMIN) ON LINUX
SETUP SCP CONNECTIVITY BETWEEN DEVELOPMENT AND
TEST/PRODUCTION

ROUNDTABLE CONSTRUCTION

12/5/2020

CREATE SECURITY GROUPS
CREATE USERS
ASSIGN USERS TO WORKSPACE AND GROUP
ASSIGN WORKSPACE SOURCES FOR EACH PRODUCT
LOAD QAD SOURCE CODE AND DATABASE OBJECTS INTO
THE SOURCE WORKSPACE
RELEASE SOURCE WORKSPACE OBJECTS AND IMPORT THEM
INTO DEVELOPMENT/TEST/PRODUCTION
LOAD INERGY CUSTOM CODE AND DATABASE OBJECTS FROM
PRODUCTION INTO THE DEVELOPMENT WORKSPACE
RELEASE DEVELOPMENT WORKSPACE OBJECTS AND IMPORT
THEM TO TEST/PRODUCTION
UPDATE INERGY CUSTOM CODE AND DATABASE OBJECTS
FROM TEST INTO THE DEVELOPMENT WORKSPACE
