Hi Mads, Great question. Unfortunately, the terminology used in the official rules for the competition is a little confusing. In the quote you reference:   "Contest Period: Widget Sample(s) may be submitted after   9:00 a.m. Pacific standard time (PST) on Friday, January 14, 2011, and must be received no later than   5:00 p.m. PST Friday, February 25, 2011 ("Contest Period").   Widget Sample(s) received before or after these dates and times will not be considered. Widget Sample(s) is considered received when accepted by Sponsor." The term "Widget Sample(s)" really means "widget competition entry form" and not the actual submission/upload of the widget(s) onto the Viewer code gallery. So, widgets that are already available on the Viewer code gallery can be entered into the competition, as long as the "widget competition entry form" is submitted within the time period specified by the official rules. Does that make sense? FYI: The Flex-A-Widget Challenge official rules FYI 2: Due to technical difficulties on our end, "widget competition entry forms" cannot be submitted today. We will start accepting widget entry forms starting Wednesday Janurary 19th, 2011. Hope this helps, ... View more

Hi Timothy, What is the hyperlink that allows me to specifically download CASE Tools for use in Visio 2003 with ArcGIS 9.3.1? To be clear, you need to have a software license of MS Visio 2003/2007. You would create your own UML model (as a Visio diagram) that defines the schema of a geodatabase. You can get the ArcInfo UML template file from the first link in my previous post: Building Geodatabases with CASE Tools (under the Support Files section > ArcInfo UML model template) Or you could edit an existing data model. When you've finished your Visio diagram, you can import it into an empty geodatabase in ArcCatalog with the Schema Wizard tool - which is available in ArcCatalog, from the Customize dialog > Commands tab > Case Tools category. You will have to add the Schema Wizard tool to the UI. Hope this helps, ... View more

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
