A system and methods are provided for interactive construction of data queries. One method comprises: generating a query based upon a plurality of user-identified data items, wherein the user-identified data items are data items representing desired results from a query, and wherein information related to the user-identified data items is included in a “given” clause of the query, assigning received input data to a hierarchical set of categories, presenting to a user a plurality of new query results, wherein the plurality of new query results are determined by scanning the received input data to find data elements in the same hierarchical categories as those in the “given” query clause and not in the same hierarchical categories as those of an “unlike” clause of the query, receiving from the user an indication as to whether each query result of the presented plurality of new query results is a desirable query result, adding query results indicated by the user as desirable to the “given” clause of the query, adding query results indicated by the user as undesirable to the “unlike” clause of the query, evaluating a metric indicative of the accuracy of the query, and responsive to a determination that the query achieves a predetermined threshold level of accuracy, storing the query.

A method for publishing relational data as XML by translating XML queries into queries against an relational database. Conversion of the relational database into an XML database is not required. Each relational table is mapped to a virtual XML document, and XML queries are issued over these virtual documents. An XML query is parsed and transformed into a language-neutral intermediate representation, which is a sequence of operations describing how the output document is derived from the underlying relational tables. The intermediate representation is then translated into an SQL query over the underlying relational tables and into instructions for a tagger. The SQL query is executed, and the SQL query results are then fed into the tagger, which follows tagger instructions to generate the marked up output.

Accordingly, a simpler query syntax and semantics can be provided to express multi-table join navigation over primary key/foreign key relations, for example.

A simple record query language (SRQL) is a generic record meta-data query solution that can natively describe the information contained in a record and search each against it to find records whose meta-data matches a particular set of criteria. SRQL includes both a record data structure that includes searchable SRQL attributes that describe the record, and queries that are able to search the attributes. The attributes are an XML node that exists in the record header itself. There are two types of queries, to wit local to find records in the local data store, and distributed to find records that may be stored in a neighbor's data store. As such, SRQL finds particular applicability to peer-to-peer networks.

A system and a method are provided for querying a knowledge resource. The querying system is configured for executing queries in a query language that accepts global backreferences that are not limited to a being located in the condition including a regular expression (regex) to which the global backreference refers.

One condition of the query includes a regex that identifies strings that match the regex. The regex includes one or more capturing groups for capturing substrings of an identified matching string. The global backreference retrieves the captured substring(s). Each global backreference in the query can be a remote backreference, which is outside the regex condition to which it refers, or a local backreference, which is in the same condition as the regex.
