Enterprise Data Management
Server based data management (Relational
database servers)
• Data definition
• Data versioning
• Data access control: user roles and user
privileges
• Concurrent transactional control
• Data publishing: publish web services
• Data backup/restore and disaster recovery
5
Enterprise Data Management (cont’)
Seamless Integration with Your Enterprise GIS
 Geodatabase based
 ArcSDE backend:
 Support geodatabase versioning
 Support geodatabase replication
 Geometry network is based on centerline data
model
 Same editing environment
 ArcGIS desktop
 ArcEngine applications
6
Enterprise Data Management (cont’)
Support Distributed Computing Environment
 Access multiple data repositories
 Support geodatabase replications
 Provide import/export utilities
 Provide dblink or dbconnect tools
 Link tables located in remote databases
 Provide support for consuming web services
 Use ArcGIS API to directly access geospatial
data in other data formats
 E.g., base map data in Google Earth services
(KML services)
7
Data Editing in Enterprise Environment
Data Versioning
 Support concurrent editing by multiple users
Data Scenario Management
 Control data editing on scenario based data
Data Editing Tools
 Network Editor

Edit highway network
 PT Editor

Edit PT network and time tabling data
 Junction Editor

Edit junction and movement data
 Accessibility Editor


Scenario Management
Model Based Scenario Management
• Cube Scenario Manager
Data Scenario Management
• Year based network
• Alternative
• Project based

Scenario Management
Model Scenario Management
• Support Cube Scenario Manager
• Store model parameters in database as metadata
−

Model Catalog
Model Application parameters
Model Scenario
Scenario key values
• Provide configuration tools to support multiple data
types:

Database tables
Linked tables
Data files
Web services
• Provide model sharing across multiple users

Scenario Data Management
Handle Data Changes in Scenarios
• Spatial Data Changes: new roads, closed roads, new intersections,
etc.
• Attribute Changes: number of lanes changes, speed changes,
capacity changes, new traffic controls, etc.
Master Network Concept
• Single version, one-stop storage
• Support multi-scenario, multi-modal, multi-year networks
• Support multiple concurrent editings
Store, track, manage Scenario data in database
• Eliminate data redundancy
• Maintain Parent-Child relationships
• Synchronize changes across scenarios
11
Scenario Data Management
Scenario Data Management for Master Network
(FSUTSM)
• Log Scenario Changes for Master Network – Database
Level
− Extracting scenario
− Log changes
− Merge changes to master network
• Cascading changes – Software Level
− Forward propagating
− Backward propagating
12
Scenario Data Management (cont’)
Scenario Data Management for Enterprise Data
Management (Cube Enterprise)
• Network definition: support multi-modal
networks
− Define network and associated features: e.g.,
highway network, PT network, etc.
• Data Scenario Definition
− Define data scenario with data group type: e.g.,
2010 highway network
• Scenario based data
− Each data entity is referenced by scenario
identifier (DataID) and network identifier
(NetworkID)
13
Scenario Data Management - Use Cases
Case 1: Data changes in scenarios
Change network spatially or in attributes
• Change network in new scenario (new year) or existing
scenario , e.g.,
− Add, edit, delete, split network links
− Change speed, number of lanes, intersection control, capacity,
etc.
Data changes outside of master network (FSUTMS)
•

•
•
14
Extract scenario network: new or existing
Make changes with Cube 5
Merge updates to master network
Propagate changes (forward or backward) to master network
Scenario Management - Use Cases
Manage data changes with Cube Enterprise
• Manage scenario in database:
− DataID: identifier for data scenario
− NetworkID: identify network group, e.g., highway vs. PT, 2010
highway
− ParentID: track parent –child relationship
− Scenario tree: track scenario along scenario tree
− Scenario tree level: tree level in a tree
− Data type: identify data group type on scenario, e.g., Highway
Network data, Speed capacity, Junction data, etc.
− Name: e.g., Base, etc.
• Extract scenario data as layer or view
− Retrieve or create scenario data as layer, instead of duplicated
copy of data
• Make changes on scenario data layer
− Cube directly edit scenario data layer
• Provide software controls on change propagation
− Allow user to selection propagation options
15
Use case: number of lanes, speed changes in scenario
• Base scenario: 2 lanes, speed 35
• Scenario 1: change 2 lanes to 4 lanes
• Scenario 2: Change speed to 45

Scenario Data Management - Use Case 2
Cube Enterprise Solution
• Maintain data scenario parent-child relationship in
database: parent-child relationship can be tracked based
on ParentDataID, DataScenarioTree and
DataScenarioTreeLevel
• Allow user to select cascading change options
− Forward cascading
− Backward cascading
• Auto-search data elements based on scenario trees
− User select cascading
− Automatic cascading
18

Data repository or container for all transport
demand modeling data
Geodatabase based, fully integrated with ArcGIS
products
Scalable implementation with or without ArcSDE
