The quickest way to share the maps you create in ArcMap with the rest of the world is to simply export them to PDF. You can send the files by e-mail or put them on Web pages.
The PDF export function in ArcMap has been enhanced so that Adobe Reader users can customize maps by turning layers, group layers, or individual members of group layers on and off.
At 9.3, PDFs exported from ArcMap can also include feature attributes that people can access interactively using the Object Data tool in Adobe Reader.
ArcGIS is supported on Microsoft Windows XP, Vista, Windows Server 2003 and 2008 (32 bit and 64 bit), Linux, and Solaris operating systems. At 9.3, ArcGIS is certified to run on the Intel and AMD 64-bit processor families.
Support for Microsoft SQL Server 2008
ArcGIS 9.3 supports storing vector geometry in either of the two new spatial types, Geography and Geometry, in Microsoft SQL Server 2008.
Support for Oracle
Enterprise ArcSDE 9.3 technology supports Oracle XE, Oracle9i, Oracle 10g, and Oracle 11g.
Support for PostgreSQL (Open Source DBMS)
The open source RDBMS PostgreSQL is now supported by Enterprise ArcSDE.
Enterprise geodatabases can be implemented on PostgreSQL with full support of the geodatabase data model.
Vector geometry can be stored in either the ESRI spatial type or PostGIS Open Source spatial type.
Support for IBM DB2 and Informix
ArcGIS 9.3 supports DB2 z/OS in Enterprise ArcSDE and also includes Informix enhancements for text search DataBlade module products.
These APIs dramatically simplify your development experience and enable you to deliver fast and user-friendly mashup GIS Web applications. The JavaScript libraries also let you embed ArcGIS Server maps, geocoding, and geoprocessing services into Google Maps and Microsoft Virtual Earth.
