7.4. Access to Data in Various Formats

Provides a function to handle data in various formats.

Nablarch provides the following two types of data input/output functions.

Although data can be accessed by using either of the above functions, use of Data Bind is recommended for the following reasons.

  • Since Data Bind can handle data as Java Beans object, the complementation of IDE can be effectively used, and the development efficiency is better. (Has the advantage that typos in item names cannot occur)
  • Format definition of General Data Format is complicated and difficult to understand. Due to this, learning cost and maintenance cost increases.


For formats that cannot be handled by Data Bind , General Data Format is required to beused.


Refer to Comparison Table of Data Bind and General Data Format for the difference between the functions provided by Data Bind and General Data Format.
