What kind of data can I store with ArcSDE 8 into a DBMS?
What is ArcSDE 8?
• All data (spatial and attributes) stored in the DBMS
Open Image Annotation Coverages Raster Shapefiles CAD DBMS What is ArcSDE 8?
How are data stored?
• in tables (attributes and geometrie) • in Geodatabase (attributes, geometrie, and metadata)
Data storage
What is a Geodatabase?
– The data that is stored in ArcSDE with an DBMS and that can contain advanced behaviors, relationships, etc.
– Data in ArcSDE that has object ids – Data that contains an object relational data model

What‘s new in ArcSDE 8?
– New ArcSDE table schema
What‘s new?
New ArcSDE 8 table schema (1.)
• Version table • Layers table • Geometry columns table • Raster columns table • Spatial references table • Table registry table • Business table
What‘s new?
New ArcSDE 8 table schema (2.)
• Versions table • States tables • Logfiles tables • Geolocation tables • Meta-data table • Logical network tables • Geodatabase tables
What‘s new?
What‘s new in ArcSDE 8?
• Table registry
What‘s new?
Table registry (1.)
Provides a central repository of tables, that the ArcSDE software manages directly or must be accessible for an application.
What‘s new?
Table registry (2.)
maintains the name, owner, and other relevant properties for tables that – contain geometry columns – contain raster columns – are multi-versioned – have a unique SE_ROW_ID column – allow row locks
What‘s new?
Table registry (3.)
• automatic - when upgrading from SDE 3.0 to ArcSDE 8.0 (all spatially enabled tables) • or directly with sde administration commands (other tables)
What‘s new?
What‘s new in ArcSDE 8?
• Long transactions with state and version support - Pessimistic and optimistic locking (versioning)
What‘s new?
Long transactions with state and version support - pessimistic and optimistic locking (versioning)
• transactions over more sessions • locking mechanism is needed
What‘s new?
Pessimistic locking
• layer locks • area locks • row locks
What‘s new?
• Versioning
Optimistic locking Default Version Town planer A

How do I get my data into ArcSDE 8 ?
• Shape Files shp2sde • Coverages cov2sde – ArcInfo 8.0: ArcCatalog / ArcToolBox • coverages • shapefiles and more...
– ArcInfo 8.0 workstation: LAYERIMPORT • SDE C-API
Data loading
How do I migrate my data from SDE 3.0 to ArcSDE 8?
• sdeexport (SDE 3) - sdeimport (ArcSDE 8) (no Geodatabase!) • creating a Geodatabase with gdbs-command --> sdeimport -->register • DBMS version compatibility?
Migration
How do I convert my data from MapLibrarian or ArcStorm to ArcSDE 8?
• Importing through ArcCatalog – series of dialog boxes will guide you – batch data converters can be used • --> simple feature types
Conversion
ArcSDE‘s Future
• ArcSDE 8.0
– New data types • raster (images/grids) • address – Java API (ArcSDE 8.1) – GUI?
Future
ArcSDE 8 Summary
• Storing spatial data in a DBMS • Many different clients • Many different databases • Cost effective data management • High performance • Open GIS
