WHAT IS SWEG
WHAT IS SWEG FOR
WHY SWEG
InSync to SWEG
CONTENT
› Introduction
› Open Smallworld data to other means than Smallworld (next to data warehouse)
› High performance;
› Improved speed for full sync;
› Configuration instead of customization;
› Low total cost of ownership
“The noblest pleasure is the joy of understanding”
Leonardo da Vinci (1454 – 1519)
What is SWEG
• SWEG is an on-demand synchronization enginethat hooks into the two databases:
✓ ORACLE
✓ Smallworld Database

User Interface
• Administration Settings
• Collection Mappings
• Datamodel
• Manage Oracle spatial
• Manage enumerators
• Manage Network connectivity (called manifolds in Smallworld)
• Process monitoring
• Logging
Unified log in Oracle Start directly from the GUI Multiple GUI instances
Monitor all running SWEG processes
LOGGING CONTROL FEEDBACK
Delete and import configurations
Clean up the target Oracle schema
Upgrade the Oracle schema
Individual SW session logs in files
“Simplicity is the ultimate sophistication”
Leonardo da Vinci (1454 – 1519)
BENEFITSConfiguration SWEG and upgrade do not interfereUpgrade to CST 5 will be simplified
SWEG 5 is compatible with CST 4.3 Make new configuration.
Advised migration path:First step: Upgrade InSync to SWEG 5 Second step: Upgrade to CST 5
Migration path InSync to CST 5
InSync
SETUP AND MAINTENANCE
Requires the creation and maintenance ofinitial mappings as well as the Oracle Spatial
metadata to match the configured Oracledatabases
Automatically creates mappings andmaintains the connection to Oracle usingconfigurations and Oracle data dictionary
Information. It has centralized log, full access to configuration metadata in Oracle and integrated
Smallworld session management.

PERFORMANCE
InSync SWEG
Very slow if Smallworld data update volume is
high
High speed ACPT interface to Oracle provides
10x or better performancegains over the native Smallworld interface.
It is scalable using multiple processes on multiple
machines for even more throughput.
SWEGGeneral Capabilities InSync
Intuitive user interface with good functions to automatically setup and
map a database✓
Intuitive user interface with good functions to automatically setup and

Several panels with multiple windows and steps to complete basic mapping
and replication
Error handling Errors produce tracebacks, handled at the sync run levels

Derived fields aresupported
complete replication of data within a single day
selected collections orfields can be re-replicated
single configuration for bothreplication andsynchronization
“One Click” migration ofconfiguration to other
environments
can sometimes take more than a day
derived fields are not supported
complete replication of data took almost 5 days
not able to re-replicate selected fields
separate configurationsneeded for replication and
synchronization
migration of configurationto other environments
is difficult

CONCLUSION
It all comes back to Fast and Sustainable Synchronization!
CONFIGURATIONSaves you on maintenance!
HIGH PERFORMANCENo more issues with small maintenance windows!
Be CST 5 ready by replacing InSynctoday with SWEG!.
