Transcript of ArcSDE
Spatial Database Engine
Why we use ArcSDE?
Asmaa M. Marouf
Introduction to ArcSDE
"Welcome to ArcSDE, the GIS gateway to your DBMS".
ArcSDE is the tool that allows you to store and manage spatial data in your chosen DBMS .
A program that can be used with different clients
A server application that works in cooperation with a DBMS.
It is a connector between DBMS and ArcGIS (server).
1. To manage data in databases.
3.Useful for application programming interface (API).
2. To connect between DBMS and
ArcGIS system(robust security, backup and recovery)
5. To enable geographic information
to be shared by many users
across any network .
We use ArcSDE to define and manage geodatabases in DBMS ,so what types of geodatabases,What kind of data can I store with ArcSDE into a DBMS.
All data (spatial and attributes) stored in the DBMS
What kind of data can I store with ArcSDE into a DBMS?
what types of geodatabases?
A geodatabase is a repository of your spatial data inside aDBMS.
The data that is stored in ArcSDE with an DBMS and that can contain advanced behaviors, relationships, etc.
A personal geodatabase stores data in a single-user RDBMS (e.g. Access). It can be read simultaneously by many users, but only one user at a time can write data to it.
Uses MS SQL Server
Uses Ms SQL Server Epress.
ArcSDE is ESRI's technology for accessing and managing geospatial data within relational databases
in the Geodatabase
4.ArcSDE is the standard interface that
allows direct access to spatial databases
from ESRI’s GIS software.
ArcSDE comes with high-level APIs for querying and
working with information in geodatabases. These include:
• ArcSDE client API for C and Java developers
• COM API (ArcObjects) for use with ArcInfo,
ArcEditor, and ArcView

An ArcGIS geodatabase is a collection of geographic datasets of various types held in file system folder, a Microsoft Access database, or a multiuser relational DBMS.
Uses DB2, Informix, Oracl PostgreSQL, SQL Server.
A file geodatabase stores data in a single-user RDBMS (e.g. Access). It can be read simultaneously by many users, and one user can write data to it per daataset.
