Hi Carlo, Is there a way in Catalog now to create the database as a diagram (a la Visio)? No, this functionality is not available in ArcCatalog. I suggest you vote for this functionality on Ideas.arcgis.com: Idea: Add a utility or tool to create, edit and analyze the geodatabase schema Hope this helps, ... View more

Hi Trixie, You can use query layers in ArcGIS Desktop and it will access data dynamically over a network/locally. However, if you want to access the data dynamically over the Web, then yes, you need ArcGIS Server. Hope this helps, ... View more

Hi Trixie, Yes, this capability is available by using "query layers" - which are SQL queries that can access spatial type data stored in a database (or geodatabase). In ArcMap, you would use a SQL query to create a new (read-only) layer. The layer behaves like any other layer in ArcMap: it can be symbolized, queried, and used in GIS analysis. If the data is updated in the database (independent of the ArcMap session), the update will appear the next time the SQL query is executed. What is a query layer? A typical workflow for ArcGIS Server users: In ArcMap, create a new query layer to access and display attribute and/or spatial type information from a database. Use ArcMap as the authoring tool for refining the query layer, such as: defining a definition query on the layer, setting symbology and labeling properties, etc. Publish the map to ArcGIS Server as an Optimized Map Service (or standard Map Service). Access the map service with ArcGIS Server clients and/or REST API�??s. In your case, you could use the ArcGIS API for Flex. Hope this helps, ... View more

Hi Joshua, 1) We are in the conceptual stage of building file geodatabases.  With moving to SDE & SQL on the horizon, what considerations should I be taking in constructing my geodatabases? A1) Please listen to the Esri Instructional podcast titled: "Migrating from Single-user Geodatabases to Multiuser Geodatabases". A transcript is also available. Esri Instructional podcasts (look under the Geodatabase filter) Do I run the risk of having to redesign my entire geodatabase from scratch once we move to SQL? A2) Geodatabase schema design is transferable between different types of geodatabases. So you could define your GDB schema in a File geodatabase, then migrate it to an ArcSDE geodatabase. But there many be some additional considerations when migrating to an ArcSDE geodatabase - please refer to the podcast. Can relationships and topology be built between datasets? A3) I believe relationship classes can exist across feature datasets. Topologies only exist within the same feature dataset. Can a dataset have both topology & geometric networks? A4) Yes, a geometric network and a topology can both exist within the same feature dataset. However, feature classes in the feature dataset can only participate in either the geometric network or the topology. They cannot participate in both data structures. Are there limits to how many feature classes can be in a given dataset? A5) I'm not aware of any known limits. The Geodatabase Diagrammer links posted above are for past versions of ArcGIS, is this ability still available for Arc 10?  A6) FYI, the Geodatabase Diagrammer has always been an unsupported Developer sample for ArcGIS. I don't believe the developer who wrote it has migrated it for ArcGIS 10. Hope this helps, ... View more

Hi Sanjay, If you are only editing the DEFAULT version, then no, you shouldn't need to do any reconcile and post operation. As Denise and Vince mentioned, these operations are only applicable when you have multiple versions in your ArcSDE geodatabase. I suggest you review this ArcUser article to learn more about the topic of versioning and the concepts of reconcile and post, Versioning 101 Hope this helps, ... View more

Hi Matthew, FYI: you can have multiple editors editing within the same File geodatabase, as long as they are editing different stand-alone feature classes or feature datasets. If you need the ability to have multiple editors editing the same feature classes or feature datasets in the same geodatabase, then yes, you will need an ArcSDE geodatabase. To start, I suggest you listen to this Esri Instructional Podcast: Migrating from Single-user Geodatabases to Multiuser Geodatabases http://www.esri.com/news/podcasts/instructional-series.html (do a filter by Geodatabase) Since you have ArcEditor/ArcInfo level of ArcGIS Desktop, you will have access to Personal ArcSDE (aka., ArcSDE for SQL Server Express) which supports 3 concurrent users, one of which can be an editor.

Hi Shakesvon, The answer to your question is "no". You cannot access Google Maps imagery outside of an interface (read: APIs) provided by Google.
