DDQB has always been strong at doing time based queries, such as in finding a diagnosis before a certain time, or finding reference to a treatment when the patient was over a certain age. In DDQB 3.2, time sensitive queries are made even more powerful by allowing time based comparisons across multiple conditions.
For example, you can now find patients where X happened within a time range of Y happening, such as a specific treatment was given within 2 weeks of a specific diagnosis. This flexibility enables the user to find these correlations at the time of the query instead of having to look at the data afterwards.
In addition to a more modern look and feel to the interface overall, the query output has some particularly helpful features, including faster scrolling, searching within the output, resizing columns, and performing additional filtering of the output after the query has run - without re-running the query. These features enable the end user to be more efficient in analyzing the data and discovering the key insights that exist in the data.
In addition to supporting the features mentioned above, DDQB Studio has integrated IBM LanguageWare technology to deliver an easier way to integrate unstructured data annotations into the DDQB environment. LanguageWare and Unstructured Information Management Architecture (UIMA) annotators allow information to be extracted from text documents. When that information is stored in the database and connected to the original document, the power to search this key information is significantly improved. By integrating the LanguageWare tooling with DDQB Studio, this is greatly simplified and gives the ability to search across both the unstructured text documents and the associated annotations, using DDQB's document viewer to highlight the search results to easily find what you are looking for.
