Cascading leverages the scalability of Hadoop but abstracts standard data processing operations away from underlying map and reduce tasks. [7] [better source needed] Developers use Cascading to create a .jar file that describes the required ...
Cascading can be implemented in terms of chaining by having the methods return the target object (receiver, this, self).However, this requires that the method be implemented this way already – or the original object be wrapped in another object that does this – and that the method not return some other, potentially useful value (or nothing if that would be more appropriate, as in setters).
Most recently the principle was carried over to application design by large software vendors, emphasized in large scale database system architecture as well as portal infrastructure and identity management. Federated identity systems link a user's attributes to multiple systems, such as with single sign-on technologies. It is also used to ...
Formally, a "database" refers to a set of related data accessed through the use of a "database management system" (DBMS), which is an integrated set of computer software that allows users to interact with one or more databases and provides access to all of the data contained in the database (although restrictions may exist that limit access to particular data).
An information cascade or informational cascade is a phenomenon described in behavioral economics and network theory in which a number of people make the same decision in a sequential fashion. It is similar to, but distinct from herd behavior .
Noted examples include the North Carolina State University library catalog (part of the Triangle Research Libraries Network) and the OCLC Open WorldCat system. The CiteSeerX project [ 12 ] at the Pennsylvania State University allows faceted search for academic documents and continues to expand into other facets such as table search.
Salesforce management systems (also sales force automation systems (SFA)) are information systems used in customer relationship management (CRM) marketing and management that help automate some sales and sales force management functions. They are often combined with a marketing information system, in which case they are often called CRM systems
