UC2008 Pre-conference Seminars*Introduction to Data Models and GeodatabasesSteve Gris

UC2008 Pre-conference Seminars

UC2008 Pre-conference Seminars*GeodatabasesMore closely represent real world objects than previous GIS data modelsProvide a starting point for more sophisticated data models based on a more natural approachRely on geography and rules to define relationships, not just primary and foreign keysUsers and Programmers dont need to manage atomic data elements/topology, they manage the objects and relationships instead

UC2008 Pre-conference Seminars*Objects and Object ClassesObjects are entities with properties and behavior.An object is an instance of an object class.All objects in an object class have the same properties and behavior.An object can be related to other objects via relationships.A row stores an ObjectA table stores an ObjectClass

UC2008 Pre-conference Seminars

UC2008 Pre-conference Seminars*Builds on the Relational ModelA feature is a spatial object.A feature is an instance of a feature class.Extended the relational model withGeometry attribute typesFeatures and Feature ClassesA feature class is a table of rows, where each row has a geographic column

UC2008 Pre-conference Seminars*Feature DatasetsA container for feature classes with the same spatial referenceAnalogous to a coverageLess restrictiveContain geometric networks and topologiesOptionally relationship classes

UC2008 Pre-conference Seminars

UC2008 Pre-conference Seminars*DomainsDescribe the legal values of a field type.Used to ensure attribute integrityCan be shared among classesTransfer with the geodatabaseTypes of domains:RangeA tree can have a height between 0 and 300 feet.A road can have between one and eight lanes.Coded value (e.g., a set)A tree can be of type oak, redwood, or palm.A road can be made of dirt, asphalt, or concrete.

UC2008 Pre-conference Seminars

UC2008 Pre-conference Seminars*SubtypesPartition the objects in a class into like groups.Defined by the value of a subtype field.Have the same attribute schemaHave the same behavior schemaCan have different default values and domains for each fieldCan define topology rules between subtypesDescriptionsCodes

UC2008 Pre-conference Seminars

UC2008 Pre-conference Seminars*An association between two object classes.A class may participate in multiple relationship classes.Related objects can message each other.Origin to destination, destination to origin, both, neither.Can trigger behavior (cascade delete, move to follow, custom, etc.)Associate rules with relationship classes.Relationship Classes
