Version Management Multiple copies of data with a “copy-on-write” approach Permanent copies and versioned copies in same database Advantages Amount of data copied optimal Conflicts detected as they occur Collaborative transactions supported Allows pessimistic and optimistic transaction What’s Oracle Workspace Manager? Long transactions and multi-versions Live Data V2 V1 V3
Transaction Type • Short Transaction • Database Editing Session lasting for a short time, i.e.: within one MicroStation Session • E.g.: split a parcel or open a valve • Locking: Only pessimistic • Pros: less overhead database side • Cons: single user editing in same area, cannot work on same project for long time
Transaction Type • Long Transaction • Database Editing Session lasting for a long time, i.e.: across multiple MicroStation Session • E.g.: creating new subdivision, engineering workflow • Locking: Pessimistic or Optimistic • Pros: Allows working on more complex projects requiring intervention multiple people • Cons: database side overhead
Locking Type • Pessimistic Locking • Database Rows are locked for the duration of the transaction • Pros: Avoid conflicts • Cons: No possibility for different alternative
Locking Type • Optimistic Locking • Database Rows are NEVER locked for the duration of the transaction • Pros: Allows evaluation of multiple alternatives, allows projects and maintenance to co-exist very well • Cons: Possibility of conflicts
Live Database Document • LIVE extraction/posting from Oracle • Create connection once, share to many users • Open a window into the spatial database • Allow editing of database data in a fixed extent or access to full extent • Allows pessimistic short/long transaction
Live Database Document • Document integrated in workflow, messaging, audit trail, security, etc • Can be referenced by other projects (always up to date reference) • Requires Constant Database Connection • Ideal for controlled Live Editing Scenario
Live Database Document • What you will see • Creation of live connection document • Bentley Map opening document • Live fetch of spatial data • Lock of spatial data • Edit of spatial data • Post of spatial data • Workflow and communication in context
What Did You Just See? • Creation of live connection document • Bentley Map opening document • Live fetch of spatial data • Lock of spatial data • Edit of spatial data • Post of spatial data • Workflow and communication in context
Disconnected Database Document • Batch Disconnected extraction/posting from Oracle • Create document once re-extraction can be commanded • Allows pessimistic/optimistic long transaction • Document integrated in workflow, messaging, audit trail, security, etc
Disconnected Database Document • Can be referenced by other projects (snap-shot reference) • Do not requires Constant Database Connection • Ideal for controlled Disconnected Editing Scenario • Field editing • Dispatching work to Sub-contractor
Disconnected Database DocumentDisconnected Viewing/Editing What you will see: • Creation of disconnected database document • Extraction and editing of Oracle Spatial data • Workflows management • Communication in context • Posting of spatial data

Multi-user editing Spatial database multi-user editing What you will see: • Multi-user editing in Optimistic Long Transaction, project can last for a very long time without disturbing operations • Geospatial Reconciliation Extension, rare conflicts can be solved • Committing any Project Version to LIVE production data
What Did You Just See? • How the Geospatial Server can be used for Multi-user editing in Optimistic Long Transaction, conflict resolution, reviewing and committing Oracle versions
Time Component • Track Edits History in the Database • Query back in time • E.g.: show me the census blocks as they were on the Census 2000 • Act on feature now and it reflected in the future • Query in the future • E.g.: show me this planned section of highway as it will be in 2007
Oracle Temporal Model • Oracle supports two modes • Valid time • Allows modeling real world dates • Allows management of past and future • Based on WM_PERIOD field • Supported for Geometry only • History • Allows to model database transaction history • Supported for Geometry and Topology • Both are based on Workspace Manager Technology
Valid Time • Queries • Any SQL Client see only the current data • SQL client has to take specific actions to see past or future • All SQL Clients are bound by valid time
History • Keep a history of changes to data • The history option lets you timestamp changes • Save of all changes or only most recent changes • GotoDate procedure allows to go back in time • Works with topology
Keeping History of changes What you will see: • Query current time • Disconnected Editing of time enable information • Query of edited information back in time
What Did You Just See? • Query current time • Disconnected Editing of time enable information • Query of edited information back in time
Oracle Spatial Topology Model • Persistent topology model in a standard RDBMS • Explicit spatial relationship existing among features • Based on topological primitives: • Nodes, Edges, Faces • Each topological primitive is stored once in the database • Each topological primitive can be associated with one or more features. For example: • An edge may be associated with two adjacent county boundaries • An edge may be associated with a land parcel and a river • Shared Editing is easier • Analysis is done using topological algorithms, using persistent relationships
Topology primitives Topology Features Features/Topology Primitives Allow finding relationships between features->Spatial Query Relationships Between Nodes/Edges/Faces Relationships Between Primitives and Feature
Bentley Topology Types • Session topology • Build the topology information on-the-fly each time it is necessary • Like in GeoGraphics 8.5 • Persistent topology • Topological primitives are created only once • Topological primitives (node, edge, face) information is in the DGN • These modes are supported with or without Oracle
DGN Persistent Topology in the DGN Bentley Persistent Topology Model • Topology is stored in the DGN • XFM features in the main DGN model • Topology primitives in an hidden model
Open from Oracle Spatial Topology What you will see: • Open Oracle Spatial Topology features in current DGN • View the topological features • Show the hidden topology model • Nodes, Edges, Faces
