When do you need ArcSDE?

When you need a multiuser geodatabase that can be edited and used simultaneously by many users, the ArcSDE geodatabase provides the solution. It adds the ability to manage both a shared, multiuser geodatabase and a number of critical version-based GIS workflows. The ability to leverage an organization's enterprise relational databases is a key advantage of the ArcSDE geodatabase.

ArcSDE also supports users who need to manage long transactions and versioned-based workflows; for example, to manage historical archives, distributed editing, federated replicas managed across many DBMS architectures, and to support multiuser editing scenarios.

ArcSDE geodatabases work with a variety of DBMS storage models (IBM DB2, IBM Informix, Oracle, and Microsoft SQL Server). ArcSDE geodatabases are used in a wide range of work groups, departments, and enterprise settings. They take full advantage of their underlying DBMS architecture to support:

Extremely large, continuous GIS databases

Many simultaneous users

Long transactions and versioned workflows

Relational database support for GIS data management (providing the benefits of a relational database such as scalability, reliability, security, backup, and integrity).

Standards-based SQL Types for Spatial when the DBMS supports this capability.

Through many large geodatabase implementations, it has been found that DBMSs are efficient at moving the type of large binary objects required for GIS data in and out of tables. In addition, GIS database sizes and the number of supported users can be much larger when using ArcSDE.
