Abstraction and/or integration can be performed on information, e.g. transaction data items in standard and/or proprietary formats, using data processing systems. For example, standard-based abstraction operations can analyze transaction data items in standard format to obtain transaction segment data items, each about a transaction segment; transaction segment data items can be used to obtain and store segment group data structures, each about a type of transaction segment data items and which can also include standard-based abstraction artifacts. Abstraction operations on standard or proprietary format can automatically extract pre-integration information, such as usage attributes. A resulting data structure can include test case scenarios, each a combination of segment group data structures with usage attributes. Integration can be performed on transaction type attribute data, producing integration attributes such as merged attribute data. A universal integration attribute language can be used, allowing comparison of segment group data structures from different proprietary formats.
