All-crimes DNA database {3}

by Ming X
Every state has its own database to store DNA information for criminal convictions.  New York planned to establish one of the most expansive DNA databases in the nation; this new database requires DNA samples for every conviction, from fare beating to first-degree murder. That’s a so-called all-crimes DNA database. Many district attorneys, sheriffs, and police chiefs support this program.

The Importance of Index Blending {Comments Off on The Importance of Index Blending}

by Alexander V
Summary:

The article was about “Index Blending” and its contribution to discipline specific research. “Index Blending is the process of database development whereby various components are merged and refined to create a single encompassing source of information. ” Index Blending combines the specific indices of other databases and other important components in order to create a single index for a particular area of study. One could say it is a “frankenstein” database where all the best resources for research are combined into one index. The process of Index Blending is very long and detail oriented. The first and most important step of the process is to determine what the problem/need is. In this instance, an area of study does not have sufficient resources and requires a more comprehensive index. The need for a more comprehensive resource is usually determined through: conducting surveys, discussions with users, and looking currently available resources. Through this process vendors determine what resources to add, remove, focus on, and or expand upon. Examples of Index Blending used by the author are EBSCO’s development of the databases Communication & Mass Media Complete and Hospitality & Tourism Index . read more...
