TABLE OF CONTENTS

The PODS Pipeline Data Modelprovides the database architecture Pipeline Operatorsuse to store critical information and analysis data about their pipelinesystems,and to manage this data geospatially in a linear-referenced database which canthen be visualized in any GIS platform.

PODS stores asset specifications, inspections, integrity, regulatory compliance, risk, historic,operational and geographic information,to support the visualization, analysis, andsystematic decision making required for responsible pipeline management.

WHATPODS DOESFORPIPELINECOMPANIES

PODS delivers a comprehensive and robust pipeline data architecturewhich meets the information and technological requirements of todays pipelinecompanies.

PODS lowers the risk, cost, and time required to implement apipeline GIS. Maintaining a single pipeline data repository helps PipelineOperators to improve the quality, quantity and timeliness of pipeline informationmanaged. Providing clear, concise definitions, and the ability to clearly delineate data

ownership, PODS promotes better business processes and work flows, and reduces datatransfer between software applications and multiple databases.

PODS leverages a broad knowledge-base, acrossmultiple pipeline operatingcompaniesand service providers, who have worked collaboratively since 1998 todevelop and refine the PODS Pipeline Data Model, deemed the best-practice pipelinedata architecture in the industry.

PODS is an Open Standard. This allows multiple vendors to develop software

products to interact with the PODS database. Pipeline Operators can choose softwareapplications based on features, cost, and usability, rather than being tied to a singlevendors proprietary data model.

PODS supports the growing needs of the pipeline industry through effective andcollaborative efforts.Membership immediately networks you into a global PODScommunity, and access to awealth of technical knowledge and experiencefrom other PODS members is made available to you.

PODS stores pipeline geographic locations, asset specifications, inspections, integrity,regulatory compliance, risk analysis, operational, and historic data to support thevisualization, analysis, and systematic decision making required for responsible pipelinemanagement. Pipeline Operators use PODS to manage, verify, analyze, maintain, and deliverrelevant information quickly and reliably to end users and applications.

Data standards (PODS) are thefoundation for quality data managementpractices. Good data managementpractices are necessary for integritymanagement, improved safety, reliability,and regulatory compliance.

PODS IMPLEMENTATIONMETHODS

THEPODS PIPELINEDATAMODELMAYBEIMPLEMENTEDASEITHERARELATIONALDATABASEORAGEODATABASE.

The PODS Relational Database may be implemented on either Oracle or SQL Server RDBMSplatforms. The PODS Relational Database has the capacity to store a variety of spatial contentand to interface with a multitude of GIS platforms.

The PODS ESRI Spatial Geodatabase has been specifically developed for implementation asan object-relational ESRI Geodatabase for use with ESRIs ArcGIS and ArcSDE products.

Unlike the PODS Relational Database, PODS ESRI Spatial can only be implemented with ESRItechnology.

Each company selects the PODS implementation method best suited to theirorganization.This decision may be based on factors such as existing IT infrastructure,

centralized or regional deployment, planned integration across their organization, usercommunity expertise, and the selection of available software applications.

PODS RELATIONAL

While pipelines are clearly linear objects, PODS Relational stores the linear nature of the

pipeline centerline deconstructed into sequenced (X, Y, Z) coordinates. This allows PODSRelational to utilize the inherent functionality found in modern Relational DatabaseManagement Systems (RDBMS).

While the PODS Relational model provides GIS neutrality, it is usually spatially enabledwith a GIS system. This allows PODS Relational to easily integrate with other IT systems anddatabases. PODS Relational is the most widely deployed enterprise implementation of thePODS Data Model.

PODS includes more than 670 tables that can be categorized into the four functional groups aslisted below.

The Core Tablesstore the pipeline hierarchy and include Line, Route, Series andStation Point. The Core Tables also define the linear distances, or stationing, usedto reference the location of Events on the pipelines. The Core Tables also store theinstructions that control how individual components are re-assembled into a pipeline

centerline.

The Location Tablesstore the centerline of the pipeline, as well as the GPScoordinates of specified features, including offline features. The Location Tables alsoserve as the translation point between the PODS Relational Database and a GeographicInformation System (GIS). The PODS Relational Database has the capacity to store avariety of spatial content and to interface with a multitude of GIS platforms.

The Event Tablesstore the information about the pipelines such as pipelinespecifications and features, operational measures, integrity and inspection results,geographic features, repair and maintenance history, analysis records, and regulatorycompliance information. These data records are stored as either linear or pointfeatures. The Event Tables also provide a mechanism to link to external documentsthrough the PODS database.

The Code Look-up Tablesare used to limit entries in certain fields topredetermined sets of allowable values. The Pipeline Operator typically determines thevalues for the Code Look-up Tables early in the implementation process. Operators canuse company-specific values, example values provided by PODS for some tables, or acombination of the two.

PODS ESRISPATIAL

The PODS ESRI Spatialmodel is a derivative of the PODS Relational model, but designed

for implementation as an object-relational ESRI geodatabase. PODS ESRI Spatial contains thetables, attributes and domains of the PODS Relational model, but is designed specifically for anESRI SDE deployment.

The PODS ESRI Spatialmodel was designed to leverage advantages inherent in ESRIGeodatabase technology, including:

The object-relational structure of the PODS ESRISpatial Geodatabase precludes the need to

manage synchronization between the relationaldatabase and a separate GIS system.

Data versioning

History tracking

Storage of ofine spatial data (such asroads, water bodies or structures)

Geoprocessing tools

Linear referencing

Interoperability with other geographic data sets
