ArcSDE functionality includes : • Serves spatial data to ArcGIS Desktop ( ArcReader, ArcView, ArcEditor, and Arclnfo ) , to Internet clients through ArcIMS , and to applications developed with ArcGIS Engine and ArcGIS Server. • Serve ESRI 's file-based data using ArcSDE for Coverages • Manage geographic information in one of four commercial databases—IBM's D132 Universal Database and Informix Dynamic Server, Oracle , and Microsoft SQL Server It is recommended that once ArcSDE is acquired , that the Division maintain and manage an ArcSDE/SQL Server configuration with assistance from the GIS Director. As aforementioned , it is recommended that the Department utilize this configuration as the basis for an enterprise-wide geodatabase . All applicable departmental data will need to be migrated to the geodatabase format in order to facilitate data sharing between the County ' s various departments . ArcIMS ArcIMS is a server-based product that provides a scalable framework for distributing GIS services and data over the Web . Currently ArcIMS is not being used ; it can be used as a platform to serve data for the County ' s recommended Internet data browser. ArcIMS provides Web publishing of GIS maps, data , and metadata for access by many users both inside the organization and outside on the World Wide Web . ArcIMS enables Web sites to serve GIS data , interactive maps, metadata catalogs , and focused GIS applications . ArcIMS users access these services through their Web browsers using HTML or Java applications that are included with ArcIMS . In addition , ArcIMS services can be accessed using many different clients including ArcGIS Desktop , custom applications created using ArcGIS Engine , ArcReader, ArcPad , ArcGIS Server, MapObjects—Java Edition , and a wide variety of mobile and wireless devices . ArcIMS will serve as the foundation for the County ' s Internet GIS Data Browser, which will provide public access to the County ' s geo-spatial data . —' Intranet GIS Data Browser An Intranet GIS Data Browser is recommended for implementation County-wide, on all networked County government computers . An Intranet GIS Data Browser is an easy-to-learn and easy-to-use web-based GIS application . It provides easy access to all County employees to display, query , and -= analyze spatial information about many aspects of the County . In contrast to an Internet GIS Data Browser, the Intranet GIS Data Browser may contain spatial layers or connect to databases that the County may not wish to share with the public . For more information on the recommended Intranet GIS Data Browser, please refer to the Enterprise-Wide Applications section of this Departmental GIS Needs Assessment Chapter. 276 GIS Needs Assessment and Implementation Plan Chapter I - Departmental GIS Needs Assessments
