Transcript

  • 1. Geodatabase Efficiencies Walter Simonazzi & Christopher Brown
  • 2. Agenda • Geodatabase design and how it can assist you • Geodatabase Storage and Migration • Versioning – When to use? – How to manage • Geodatabase Replication • Performance and Maintenance
  • 3. Department of Spatial Awareness Dave • New Spatial Data Administrator • Existing Organisation Planning Operations Media
  • 4. Department of Spatial Awareness Dave • Lots of Corporate Data stored in “silo’s” • A lot of project data stored on peoples computers • No specified data standards • The data has been stored in SDE – Where no one knows what is there – Everyone complains about poor performance
  • 5. Department of Spatial Awareness What should Dave do now? • Identify the workflows in the organisation • Create a data governance document – What do the users need to do to make the data useful to the organisation • • • • Create a Data Model Import the data into the new data model Setup an edit workflow Manage the ongoing performance of the Database
  • 6. What’s in a geodatabase design? GIS behavior Rules Tools Elements Single-user Multiuser Geodatabase
  • 7. Geodatabase functionality Default attribute values Subtypes Single-user Multiuser Attribute domains Attachments Relationship classes Topology
  • 8. Workflow: From design to prototype Design the geodatabase Obtain schema Modify schema Add data Prototype geodatabase
  • 9. What should Dave do next? • Speak to Barry • Barry is the Corporate DBA – It is Barry’s job to make sure that the databases perform The key to Enterprise GIS is a collaboration between the business systems and the spatial architecture
  • 10. Diagrammer & Case Tools (free tools) • ArcGIS Diagrammer is a productivity tool for GIS professionals to create, edit or analyze geodatabase schema. • Is a visual editor for Esri’s .xml Workspace Document • *Supports complex geodatabase elements such as topology and parcel fabrics http://www.arcgis.com/home/item.html?id=5af1723bab4e413bae63dd89daa87984
  • 11. CDB If I build it, they will come ArcGIS Geodatabase and CASE Tools
  • 12. What’s in the Geodatabase?
  • 13. What’s in the Geodatabase?
  • 14. What’s inside the Geodatabase?
  • 15. What’s inside the Geodatabase? - Pre-configured table - 370 configuration parameters
  • 16. ArcSDE and the DBTUNE table Client Translator Database Server Select… DBTUNE Repository
  • 17. ArcSDE compressed binary • Better performance for advance geodatabase elements • Reduce the storage size in the RDBMS • Difficult to access with SQL commands and third party applications
  • 18. Spatial field types • The default format in ArcSDE • Easy access with SQL operators and spatial functions.
  • 19. Supported Storage types
  • 20. Migrating spatial types Supported migration paths SQLServer • • SDE binary to Geometry SDE binary t Geography Oracle • • SDE binary to ST_Geometry SDO_Geometry to ST_Geometry
  • 21. WS Put it in the bucket Storage and Migration
  • 22. Like a Version D77 SDE_STATE_ID # DELETED_AT Unique object ID  Constant for all versions of a row # # SDE_DELETES_ROW_ID A77 SHAPE NAME OBJECTID SDE_STATE_ID Database state  Identifies when row was added CELL_TOWERS SHAPE 1 2 3 NAME Riverside NE Riverside SE Riverside W OBJECTID 1 2 3 SDE_STATE_ID 0 0 0
  • 23. Like a Version - Adding D77 SDE_STATE_ID SDE_DELETES_ROW_ID DELETED_AT # # # # A77 SHAPE 4 NAME OBJECTID 4 SDE_STATE_ID 1 CELL_TOWERS SHAPE 1 2 3 NAME Riverside NE Riverside SE Riverside W OBJECTID 1 2 3 SDE_STATE_ID 0 0 0
  • 24. Like a Version - Deleting D77 # # # SDE_STATE_ID 0 SDE_DELETES_ROW_ID 2 Created at state DELETED_AT 2 Deleted at state A77 SHAPE 4 NAME OBJECTID 4 SDE_STATE_ID 1 CELL_TOWERS SHAPE 1 2 3 NAME Riverside NE Riverside SE Riverside W OBJECTID 1 2 3 SDE_STATE_ID 0 0 0
  • 25. Like a Version - Updating D77 # # Riverside Mid SDE_STATE_ID 0 1 SDE_DELETES_ROW_ID 2 4 DELETED_AT 2 3 # A77 SHAPE 4 4 NAME OBJECTID 4 Riverside Mid 4 SDE_STATE_ID 1 3 CELL_TOWERS SHAPE 1 2 3 NAME Riverside NE Riverside SE Riverside W OBJECTID 1 2 3 SDE_STATE_ID 0 0 0
  • 26. Versioned Editing Performance • Performance affected by: 0 – Volume of states – Stale statistics – Unnecessary versions* – Proper workflow State 0 Version pinning v2 state tree • Manage your version – Reconcile – Post – Compress v1 v4 DEFAULT
  • 27. To Version or not to Version
  • 28. CDB Who’s afraid of the big bad version? Version Creation and Management
  • 29. What is Geodatabase Replication? • Geodatabase replication allows you to create copies of data across two or more geodatabases and to keep data synchronized. • Geodatabase replication allows to replicate just the elements you want.
  • 30. Three types of Replication PARENT CHILD Sync both directions Two-way One-way Sync one direction Check-out once Check-out/ check-in Check-in once
  • 31. Preparing data for replication Data requirements Stored in high-precision spatial format Registered as fully versioned in 2wR (no move to base) Non-versioned or fully versioned in 1wR (no move to base) Must have global ids The database user must have write permission to the data
  • 32. Create a Replica • Distributed Geodatabase toolbar • Create Replica tool • Arcpy
  • 33. WS Replica versus Replicant Using Replication
  • 34. No LAN/WAN between offices? Replication using Geodata services
  • 35. Real time edits Use Replication to avoid service interruptions
  • 36. Privileges • Data set privileges managed from ArcCatalog
  • 37. Performance Bottlenecks Client interaction Network Server hardware DBMS/ ArcSDE ArcMap TCP/IP User interaction SQL Multiuser geodatabase Results presented SQL TCP/IP ArcMap DBMS server
  • 38. Attribute indexes WHERE value > 10 Use Index
  • 39. Spatial indexes Select by Location Use Spatial Index
  • 40. Statistics Small table Full Table Scan Large table Use Index
  • 41. Scheduling tasks Windows Scheduler Python Script arcpy.RebuildIndexes_management… arcpy.AnalyzeDatasets_management…
  • 42. Responsibilities Dave Barry Compress Analyse Attribute Indexes Attribute Indexes Spatial Indexes Database Statistics
  • 43. ALL Keep on Running Performance and Management Techniques
  • 44. Summary • Design and maintain your geodatabase to support your business processes. • Every minute you spent thinking about the design of your geospatial database can save you hours of frustration. See you at the Booth * The view of the presenters is not always the views of anybody else
  • 45. Training • Building Geodatabases • Configuring and Managing the Multiuser Geodatabase • Implementing Versioned Workflows in a Multiuser Geodatabase • Distributing Data using Geodatabase replication Training website http://esriaustralia.com.au/training
  • 46. Other Resources • Come chat to us at the Industry Solution booth on the conference • ArcGIS Resources – Geodatabase Community http://resources.arcgis.com/en/communities/geodata/ • GIS Wiki http://wiki.gis.com/wiki/index.php/Main_Page • Esri Online Training Gateway http://training.esri.com/gateway/index.cfm
  • 47. Questions? Thank you
