+#### Based on the flow, there are 4 main components (4 main ports):
+- Reader, Validator, Transformer, Writer
+##### Reader
+Reader Adapter Sample: File Reader. We provide 2 file reader adapters:
+- Delimiter (CSV format) File Reader
+- Fix Length File Reader
+##### Validator
+- Validator Adapter Sample: Schema Validator
+- We provide the Schema validator based on GOLANG Tags
+##### Transformer
+We provide 2 transformer adapters
+- Delimiter Transformer (CSV)
+- Fix Length Transformer
+##### Writer
+We provide many writer adapters:
+- SQL Writer: to insert or update data
+- SQL Inserter: to insert data
+- SQL Updater: to update data
+
+- SQL Stream Writer: to insert or update data. When you write data, it keeps the data in the buffer, it does not write data. It just writes data when flush.
+- SQL Inserter: to insert data. When you write data, it keeps the data in the buffer, it does not write data. It just writes data when flush. Especially, we build 1 single SQL statement to improve the performance.
+- SQL Updater: to update data. When you write data, it keeps the data in the buffer, it does not write data. It just writes data when flush.
+
+- Mongo Writer: to insert or update data
+- Mongo Inserter: to insert data
+- Mongo Updater: to update data
