SQA: The Oracle Problem

Testing involves examining the behaviour of a system in order to discover potential faults.

The problem of determining the desired correct behaviour for a given input is called the Oracle Problem. 

Since manual testing is expensive and time consuming there has been a great deal of work on automation and part automation of Software Testing. However, the problem of automating the Oracle remains a bottleneck that inhibits progress in increased automation for test effectiveness and efficiency.

structured, semistructured, unstructured data

Structured data is data that is organized into entities that have a defined format, such as XML documents or database tables that conform to a particular predefined schema. This is the realm of the RDBMS.

Semi-structured data, on the other hand, is looser, and though there may be a schema, it is often ignored, so it may be used only as a guide to the structure of the data: for example, a spreadsheet, in which the structure is the grid of cells, although the cells themselves may hold any form of data.

Unstructured data does not have any particular internal structure: for example, plain text or image data.
