A system cooperable with a data engine such as a database allows a user to refine a query. The query comprises at least one conditional attribute and at least one attribute to be displayed and the data engine responds to produce a report comprising one or more objects, each object comprising the displayed attributes. The system comprises a module for rendering at least one object from a report and which is responsive to user interaction with the report, for selecting one or more displayed attributes and causing the one or more displayed attributes to change to respective one or more conditional attributes. A second module renders at least one conditional attribute for a query and is responsive to user interaction with the one or more rendered conditional attributes, for selecting one or more conditional attributes and causing the one or more conditional attributes to change to respective one or more displayed attributes. |

DETAILED DESCRIPTION OF THE INVENTION In describing the operation of the system, for clarity, reference will be made to the operation of classes whereas it is to be understood that it is instances of such classes which execute at run time.

09/342,775 describes a set of Java beans one of which, DBQuery 30, connects via a database driver 32 to a relational database 34.
The relational database 34 comprises a plurality of tables 36, Relation #1 .
.
.
#x, each of which store a number of attributes for a number of objects.
DBQuery comprises a number of properties including the address and type of the database and any username and password required to access the database 34.
From the point of view of the present invention, two properties are relevant: Query and DBResultSet.
DBQuery also exposes get and set methods enabling its properties to be read and, where possible, written by other objects.
In the present embodiment, a text entry field 38 receives user input directly defining an initial SQL query--SQL Query #1.
Where the user is not expected to be familiar with such query languages, user input can be via a natural language interface 40, which receives input, for example, "Get me all red 4 wheel drive cars in your catalogue", and converts this to an initial SQL query.
Again, it should be seen that the present embodiment is described in relation to SQL and relational databases for exemplary purposes only, and it will be seen that the invention is applicable to any means for querying any data engine including databases, data stores, simulation tool or combination thereof.
For example, initial input could be made from a QBE type interface or indeed initial input might be limited to only specifying conditions for a limited number of attributes with the remainder of the query being pre-defined or built automatically.
In any case, initial user input is used to set the Query attribute of DBQuery 30.
This causes DBQuery 30 to link to the database 34 and generate a report which is returned as a relation called DBResultSet
