In this section we are going to discuss the basic and important Ab initio components:
Dataset components represents data records or act upon data records as follows:
Input file:
Input file can be the source file that is read as input for the graph.It can either be serial or multifile depend upon the requirement.
Input table:
It unloads the data records from the database into the Abinitio graph allowing you to specify either the source table or an sql statement that extracts the data records from one or more records.
Intermediate file :
It represents one or more serial files or multifile of intermediate results that a graph write during execution and save for review after execution.
Look up :
Lookup basically contains the one or more serial files or multifile of data records small enough to be held in the main memory let the transform retrieve the data records quickly than to be kept in disk.
Output file:
It writes the data records to one or more serial files or multifiles.
Output table:
It writes the data records to database letting you to write the data records either directly by providing the record destination table name or by writing the sql that inserts the records in one or more tables.
Read Multiple files:
Reads the data sequentially from list of file.
Write Multiple files:
Writes the records to the set of output files.
