Overview

The Oracle Spatial Point Cloud Reader/Writer module enables FME to read and write Point Cloud and attribute data stored using Oracle Spatial. This module communicates directly with Oracle Spatial for maximum throughput.

If only attributes are to be read or written, the Oracle Non-Spatial Reader/Writer module should be used.

This section assumes familiarity with Oracle Spatial, its Point Cloud support, and its indexing mechanisms.

Tip: The FeatureReader transformer performs queries against any FME-supported format.

Reader Overview

This reader reads point cloud tables from Oracle Spatial databases.

Writer Overview

The Oracle Spatial Point Cloud writer module stores point cloud and attribute data in an Oracle Spatial database. Only uppercase table names are supported.

The Oracle Spatial Point Cloud writer provides the following capabilities:

  • Transaction Support: The Oracle Spatial Point Cloud writer provides transaction support that eases the data loading process. Occasionally, a data load operation terminates prematurely due to data difficulties. The transaction support provides a mechanism for reloading corrected data without data loss or duplication.
  • Table Creation: The Oracle Spatial Point Cloud writer uses the information within the FME mapping file to automatically create database tables as needed. Creation of related tables is also supported, such as the block table for Point Cloud columns. Metadata tables and triggers are also created or updated accordingly.
  • Table Dropping: The Oracle Spatial Point Cloud writer has an option that allows each table to be written to be dropped if recreating, or truncated if appending. Likewise, related tables, such as block tables for point cloud columns, will be dropped when empty. Metadata tables are updated via Data Manipulation Language (DML) triggers; however, the triggers themselves are not currently dropped.
  • Index Creation: The Oracle Spatial Point Cloud writer will set up and populate all needed indexes and index tables as part of the loading process.
  • Bulk Loading: The Oracle Spatial Point Cloud writer uses a bulk loading technique to ensure speedy data load.
