Information required to answer

As analytical chemists, we are often called upon to participate in studies that require the measurement of chemical or physical properties of materials. In many cases, it is evident that the measurements to be made will not provide the type of information that is required for the successful completion of the project. Thus, we find ourselves involved in more than Just the measurement aspect of the investigation —we become involved in carefully (re)formulating the questions to be answered by the study, identifying the type of information required to answer those questions, making appropriate measurements, and interpreting the results of those measurements. In short, we find ourselves involved in the areas of experimental design, data acquisition, data treatment, and data interpretation. 

It must be emphasised that, although all the information required to answer the questions correctly is available in the recommended textbooks, do not try to verify all the information. 

The overall architecture of DiscoveryLink is common to many heterogeneous database systems. Applications connect to the DiscoveryLink server using a variety of standard database client interfaces, such as Open Database Connectivity or Java Database Connectivity, and submit queries to DiscoveryLink in standard SQL. The information required to answer the query comes from one or more data sources, which have been identified to DiscoveryLink through a process called registration.
