Overview

The CSF_MD_HYDROS table is a core data object within the Oracle E-Business Suite (EBS) Field Service (CSF) module. It serves as the master repository for defining hydrographic features, which represent bodies of water and related geographical elements critical for field service planning and execution. In the context of EBS 12.1.1 and 12.2.2, this table plays a foundational role in the spatial and geographical data model, enabling service organizations to accurately map and manage assets, territories, and service routes in relation to water features like rivers, lakes, and coastlines. Its data is essential for logistics, dispatch optimization, and field resource management where hydrological geography is a factor.

Key Information Stored

While the provided metadata does not list all columns, the structure is defined by its primary and foreign keys. The central column is HYDROGRAPHY_ID, a unique identifier serving as the table's primary key. This ID is the definitive reference for any hydrographic feature within the system. Another documented column is INST_STYLE_ID, which links the hydrographic feature to an installation style definition, likely controlling its visual representation or classification in mapping interfaces. The table presumably contains additional columns to store attributes such as feature name, type, geographical coordinates, and other descriptive metadata necessary for its definition within the Field Service application's framework.

Common Use Cases and Queries

This table is primarily accessed for geographical data integration, reporting, and application logic within the Field Service module. Common use cases include generating maps that overlay service territories with hydrographic features, performing spatial queries to find service sites near specific water bodies, and validating field resource travel plans. A typical query would involve joining CSF_MD_HYDROS with other spatial or service data tables. For example, to retrieve a list of all hydrographic features with their associated installation style, one might use a SQL pattern such as: SELECT h.hydrography_id, h.inst_style_id, s.style_name FROM csf_md_hydros h, csf_md_inst_style_shts s WHERE h.inst_style_id = s.inst_style_id;. Reporting often focuses on summarizing features by type or region for logistical analysis.

Related Objects

Based on the documented foreign key relationships, CSF_MD_HYDROS is integrated with the following key objects:

  • CSF_MD_INST_STYLE_SHTS: Linked via the INST_STYLE_ID column. This relationship associates each hydrographic feature with a specific installation style sheet, which governs its presentation or thematic attributes.
  • CSF_MD_NAMES: Linked via the HYDROGRAPHY_ID column. This is a critical relationship where CSF_MD_HYDROS is the parent table. The CSF_MD_NAMES table stores naming information (potentially in multiple languages or formats) for the hydrographic features defined in CSF_MD_HYDROS, using the HYDROGRAPHY_ID as the foreign key reference.
