Disclosed herein is a user interface and methods for building a formulated query to search a database of structural data which is organized by classes, attributes of classes, literals of attributes, and structural relations between classes. The user interface can display results of the formulated query and includes a structural query section to define constraints for the formulated query. The structural query section includes one or more query elements to be populated and a means for adding one or more additional query elements, wherein each query element can have a class portion which is populated by designating one of a special class identifier and a concrete class identifier, and can have one or more attribute and literal portions. The class portion can be populated by designating the class identifier from an offered list, and the user interface can further include an offer section which displays the offered list. The offered class identifiers, relation identifiers, attribute identifiers and literal values can come from the particular searched structural data. The offered class identifiers, relation identifiers and attribute identifiers can come from the definition of the structural content of the searched data. A relationship between query elements is expressible using a defined structural relation, such as a 'contains' relation. Relationships between two or more query elements or two or more query element attribute-literal pair portions are also expressible using logical relations, such as a logical 'AND' relation, a logical &#x201c;OR&#x201d; relation, and a logical &#x201c;XOR&#x201d; relation. A query results section displays results of the formulated query after the formulated query is executed.

User interface and methods for building structural queries

The invention provides a system and method for retrieving and storing industrial data, the system comprising a data retriever that includes a data retrieval manager and one or more watchers for monitoring data associated with one or more industrial devices, wherein if the data associated with the one or more industrial devices is new or modified, the one or more watchers notifies the data retrieval manager thereof and the data retrieval manager uploads the new or modified data. The system further includes a database manager for receiving the new or modified data in a first form from the data retrieval manager and for storing the new or modified data in a structural data form in one or more databases.

System and method for retrieving and storing industrial data

A search utility for industrial control programs accepts as a query an example program fragment which is abstracted into a graph-form capturing, for example, instruction control-flow and data-flow. This graph-form may be compared to a graph-form transformation of other portions of the program to provide a more sophisticated matching process that considers underlying logical hierarchy of the program elements rather than their superficial expression in the source code embodiment.
