A database index is a data structure that improves the speed of data retrieval operations on a database table at the cost of additional writes and storage space to maintain the index data structure. Indexes are used to quickly locate data without having to search every row in a database table every time a database table is accessed. Indexes can be created using one or more columns of a database table, providing the basis for both rapid random lookups and efficient access of ordered records.
An index is a copy of select columns of data from a table that can be searched very efficiently that also includes a low-level disk block address or direct link to the complete row of data it was copied from. Some databases extend the power of indexing by letting developers create indices on functions or expressions. For example, an index could be created on upper(last_name), which would only store the upper case versions of the last_name field in the index. Another option sometimes supported is the use of partial indices, where index entries are created only for those records that satisfy some conditional expression. A further aspect of flexibility is to permit indexing on user-defined functions, as well as expressions formed from an assortment of built-in functions.
The professionalization of economics, reflected in academia, has been described as "the main change in economics since around 1900." Economists debate the path they believe their profession should take. It is, primarily, a debate between a scholastic orientation, focused on mathematical techniques, and a public discourse orientation, which is more focused on communicating to lay people pertinent economic principles as they relate to public policy. Surveys among economists indicate a preference for a shift toward the latter. However, these preferences expressed in private often differ with what is actually acted out in the public eye.
The Economist is an English language weekly newspaper owned by the Economist Group and edited in offices based in London. Continuous publication began under founder James Wilson in September 1843. For historical reasons, The Economist refers to itself as a newspaper, but each print edition appears on small glossy paper like a news magazine. In 2006, its average weekly circulation was reported to be 1.5 million, about half of which were sold in the United States.
The publication belongs to The Economist Group. It is 50% owned by private investors and 50% by Exor, the Agnelli holding company, and the Rothschild banking family of England. Exor and the Rothschilds are represented on the Board of Directors. A board of trustees formally appoints the editor, who cannot be removed without its permission. Although The Economist has a global emphasis and scope, about two-thirds of the 75 staff journalists are based in the City of Westminster, London. As of March 2014, the Economist Group declared operating profit of £59m. Previous major shareholders include Pearson PLC.
