Why Use IBM Info Sphere DataStage for ETL Processes
IBM Info Sphere Information Server is a suite or it can say an umbrella of many integrated solutions with advantages of Profiling, Cleansing, Extraction, Transformation, De-Identification and Loading. IBM Info Sphere DataStage is Data ware housing ETL tool and part of the IBM Information Platforms Solutions suite. Datastage uses a graphical notation to construct data integration solutions and make life easier for the ETL process developer.DataStage, workload automation, DataStage Integration, Datastage, ETL, Datastage tutorial, datastage training, datastage course, datastage lessons for please visit Foryooth.blogspot.com.
IBM Info Sphere DataStage provides a series of Advantages like
Flexible Development Environment to ETL Process Developers. With its Feature Rich Designer developer can develop their processes in their desired manner and can even plan components which can be reused. Feature Like multiple instance of single process allows to share and remove redundancy of processes across enterprise. ETL developer can perform the data integration process quickly and even can mane use of extensible objects and functions apart from implementing customized functions and use them.
With IBM Info Sphere DataStage or ETL developer can not only retrieve data from heterogeneous applications but also can join data at source level or at DataStage level and apply any business transformation rule from within a designer without having to write any procedural code.
With the introduction of Information Server, common data infrastructure used for data movement and data quality (metadata repository, parallel processing framework, development environment) and provide a complete Data Lineage.Off course all this along with capability of executing the ETL process in parallel mode with unlimited scalability and maximum utilization of hardware resources.
When to use which stage in Datastage?
Copy STAGE-To drop a Particular column
Sort STAGE-sorting,generating Key change and similar to order by clause in oracle
Filter STAGE-Similar to where clause in oracle but we can not perform Join operation
Lookup,Join,Merge-To perform Join operation
Pivot Enterprise STAGE-Rows to columns and columns to Rows
External Filter STAGE-Filter the records by using Unix filter commands like Grep etc
MODIFY STAGE-Metadata conversion,Null Handling and similar to conversion functions in oracle
FUNNEL STAGE -Combining the multiple input data into a single output.Metadata should be same for all the inputs
REMOVE DUPLICATES STAGE-To remove duplicate values from a single sorted input.
ENCODE / DECODE STAGES:To encode/compress a data set using UNIX encoding commands like gzip etc
TRANSFORMER STAGE:
a)Filtering the Data(constraints)
b)Metadata conversion(Using Functions)
c)Rows to columns and columns to Rows(Using Stage variables)
d)Looping
e)Creating a counter(Using macros)-Counter using Transformer
SURROGATE KEY GENERATOR STAGE-To generate SURROGATE KEYs similar to oracle Database sequence
Aggregator Stage: To perform Group by Operations like max,min etc similar to Group by clause in oracle
ROW GENERATOR STAGE: To generate a set of mock data fitting the specified metadata when no real data is available
XML OUTPUT STAGE -To convert tabular data such as tables and sequential files to XML hierarchical structures.
SWITCH STAGE- It performs an operation similar to the switch statement in C and to filter the data
CHANGE CAPTURE STAGE-To identify Delta changes(inserts,updates,deletes etc) between two sources
oracle connector-To connect to the oracle Database.
