When loading raster data into an enterprise geodatabase, users can specify four raster storage settings: compression, pyramids, statistics, and tile size. This discussion focuses on some best practices for these settings, and raster data throughput between clients and the server. It is recommended that you are familiar with raster data concepts and ArcSDE architecture. —Derek Law, Product Management, ESRI; published August 10, 2007.
This discussion focuses on some best practices to help maintain the performance of an enterprise geodatabase. The content of this discussion is not specific to any supported database and is therefore applicable to all database administrators and ArcSDE managers. It is recommended that you are familiar with database and ArcSDE architecture and terminology. —Derek Law, Product Management, ESRI; published May 10, 2007.
ArcGIS 9.2 introduces a new method of maintaining a historical record of your data, called geodatabase archiving. When archiving is enabled, changes to your datasets are recorded and can later be queried to view the state of features at any point in history. This discussion describes how the geodatabase implements this archiving capability and includes general topics about historical data. —Owen Evans, Technical Marketing, ESRI; published August 15, 2006.
This second discussion on geodatabase archiving focuses on the new tools
that ArcGIS 9.2 provides for working with archived data. Several methods of
viewing and interacting with historical versions in ArcMap are covered, along
with constructing historical queries. It is recommended that you are familiar
with the new archiving functionality and suggested that you first listen to
the podcast episode Geodatabase Archiving: Introduction to Concepts and
Capabilities. —Owen Evans, Technical Marketing, ESRI; published November 7, 2006
ArcGIS 9.2 introduced a new method of distributing shared datasets across several servers. This discussion describes the introductory concepts of geodatabase replication, such as the types of replica that can be created and the different methods available for synchronization. Also presented are several examples of where distributing your data using this capability may help to simplify data sharing workflows. —Owen Evans, Technical Marketing, ESRI; published February 13, 2007.
Geodatabase replication enables the distribution of datasets across several geodatabases, and provides a mechanism for keeping those datasets in synch by sending changes over the network or the Internet. This discussion contains suggestions for planning a replication strategy that will help you implement a comprehensive distributed data workflow. The mechanics of creating and synchronizing replicas are also discussed. —Owen Evans, Technical Marketing, ESRI; published November 20, 2007.
Bundled database servers are new at ArcGIS 9.2 and include personal geodatabases (Personal ArcSDE) and workgroup geodatabases (Workgroup ArcSDE). This discussion will describe the implementation and capabilities of these two levels of the scalable geodatabase. —Derek Law, Product Management, ESRI; published April 24, 2007.
The geodatabase is the common data storage and management framework for ArcGIS. This discussion describes what a geodatabase is and how GIS data is stored within it. It outlines five reasons why it is an advantageous data format for ArcGIS users to implement. —Derek Law, Product Management, ESRI; published March 20, 2007.
The release of ArcGIS 9.2 Desktop will include significant enhancements for managing cartographic data in the geodatabase. This podcast discusses some of the data management issues that you need to consider to prepare your data for this new functionality. It is intended for cartographic and map production specialists, as well as geodatabase administrators. —Peter Kasianchuk, Instructor, ESRI; published August 1, 2006.
This discussion offers three tips for effective raster data management in an enterprise geodatabase. It is recommended that you are familiar with the geodatabase, raster data concepts, and ArcSDE architecture. —Derek Law, Product Management, ESRI; published December 11, 2007.
At ArcGIS 9.2, three different types of geodatabases are available: Microsoft Access-based personal geodatabase, file geodatabase, and scaleable geodatabase. The scaleable geodatabase is offered at three levels: personal, workgroup, and enterprise. This discussion will describe the different types of geodatabases and their implementations and will contrast their properties. —Derek Law, Product Management, ESRI; published April 10, 2007.
Derek Law, Geodatabase Technical Analyst at ESRI, gives an overview of what's new in the ArcGIS 9.3 Geodatabase. —Derek Law, Geodatabase Technical Analyst, ESRI; published April 10, 2008
