A method and system for building a relational database is disclosed. An input file is converted to obtain a converted file comprising a plurality of data element types, and the data element types are formatted and concatenated to obtain formatted data comprising a tag associated with each of the data element types. The formatted data within an identified structure is filtered by the tag to identify an identified data element type form the plurality of data element types. At least one relational identifier is correlated to the identified data element type to obtain a relational dataset, and the relational dataset is stored in a table corresponding to the identified data element type to build a task information relational database for the identified structure.
