Creating a Data Source
Data Source refers to the physical structure or location of the source system.
The Data Source can be a file, a table, or WebLogs.
- In case of File, it can be a flat file that can be local to OFSAA or remote to OFSAA, or a file on HDFS.
- In case of a table, it can be an RDBMS table or HDFS table.
- In case of WebLogs, it can be in a local file system or in an HDFS cluster. If it is in the HDFS cluster, you must register a cluster with the required information from the DMT Configurations>Register Cluster window.
For tables, the connection and authentication details are defined in the System
Configuration > Database Details section. Proper connection pooling must be
done, if you have to create an external Data Source on a database without an Information
Domain created on it. Applications access the data source using an FTP
connection.
Note:
- Source creation implicitly does a source model generation.
- Defining the structure of a Flat File is mandatory during the creation of Flat File based sources.
- Data Sources cannot be defined on Configuration Schema. By default, OFSAA generates Data Sources on Configuration Schema and they can only be viewed; you cannot edit them.
To create a Data Source follow these steps:
