SECTION 1: INTRODUCTION TO ARCSDE

WHAT IS SDE?

ArcSDE (Spatial database engine) is a system that stores spatial data in a database management system. ArcSDE manages spatial data using IBM DB2, IBM Informix, Microsoft SQL Server, or Oracle, and allows one to serve spatial data to remote clients. ArcSDE delivers spatial data to ArcGIS Desktop users through a direct, read-only connection from the client’s machine to ArcSDE.

WHAT DOES THIS MEAN FOR GIS USERS?

ArcSDE allows remote users to access both raster and vector GIS datasets for use in their projects.

The use of ArcSDE eliminates the need to download data and store it locally. This saves time and resources as well as simplifies file management for the client.

An SDE connection keeps an active link to SDE data, regardless of where a map document file (MXD) is located (or moved to) on the client's computer.

Because data is stored in a topological geodatabase format, accurate length and area is calculated and reported within the database.

Users have read-only access to datasets on this network.

HOW DO GIS USERS USE THIS INFORMATION?

ArcSDE layers function identically to a shapefile or coverage in ArcMap, save for the fact that you are not allowed to edit the dataset.

SECTION 2: CONNECTING TO ARCSDE

6

CONNECTING TO ARCSDE STEP 1: If not already done, set up the client service. All ISU client connections have the same user name: sdeclient. Each client machine should have a service called "esri_sde" in its service file. The file "services" is found in C:\Windows\SYSTEM32\DRIVERS\ETC\.

1. Open this file with NOTEPAD 2. Add the following line into the file (followed by at least one carriage return if this is the last line

of the file): esri_sde 5151/tcp #Esri ArcSDE server Note: This step is not mandatory since you can type "5151" for the service in step 3, instead of "esri_sde". However, entering the number will not allow you to access Layer files (see XXX). Therefore, modifying this file is considered quite important.

STEP 2: CONNECTING WITH ARCGIS 10.1 OR LATER You must connect using the “Create ArcSDE Connection File” tool found in ArcToolbox—DATA MANAGEMENT TOOLS—WORKSPACE---CREATE ARCSDE CONNECTION FILE. An example connection is shown below:

7

Note: The user sdeclient (password: SDE_guest) can view geospatial data stored in the sdeaoc database, but not add to the database or edit data stored in the database. Once created as shown above, the connection file may be easier for users to locate as it can be placed in their normal workspace (see below)

SECTION 4: LAYER FILES

19

USING ARCSDE LAYER FILES

Ideally, layer files are meant to load all layers involved automatically. This does not always happen. Sometimes the layer file loses its data source information, as indicated by the red exclamation point in a grayed out box next to the layer file. To fix this, follow these instructions:

1) Right click on the layer that has the red exclamation point. Select Properties. See

Fig. 1 2) Under properties, find the Source tab. Click Set Data Source. 3) Browse to your SDE connection and find the file that corresponds to that layer. See

Fig. 2. 4) Repeat the above steps until all layers are fully displayed.

If this problem occurs often, check your service and host files under C:\WINNT\System32\drivers\etc to see if they have been updated to support the ArcSDE service. If you are not sure how to check these files or if these files are not updated, follow the Connecting to ArcSDE instructions found on page 6 of this booklet.

SECTION 5: RESEARCH FEATURE DATASET

23

WHAT IS A FEATURE DATASET? “A feature dataset is equivalent to a directory or a folder in a computer operating system. It is used to help organize the data into a logical structure. It can contain feature classes and relationship classes, but not tables.” University of Arizona Knowledge Base Website, http://ag.arizona.edu/art/kb/geodb/geo_info.html

WHAT IS A FEATURE CLASS? “Feature classes in geodatabases are collections of features with the same type of geometry. If several feature classes share some spatial coincidence and a common spatial reference, they can be inserted into a feature dataset.” Colin Childs, Migrating Coverages to Geodatabases, ArcUser, July to September, 2001

WHAT’S INSIDE THE RESEARCH FEATURE DATASET

YEAR 2XXX FIELD SAMPLES SDEAOC.SDEMGR.Y2xx_Field_Samples Within the Research feature dataset are point feature classes describing field sample points taken from 2000 to the present. In addition, relationship classes have been created that allow the user to automatically access related data in ArcGIS without the need to create joins and links. Examples of these additional data are vegetation details, fire history, grazing, and sagebrush sampling details. To view a detailed model of the Research Feature Dataset, visit http://giscenter.isu.edu/spatial_library/SDE/Model/root.html (then open the "main" window under the fully expanded "<<Feature Dataset>> Research").
