DATAR, short for Digital Automated Tracking and Resolving, was a pioneering computerized battlefield information system. DATAR combined the data from all of the sensors in a naval task force into a single "overall view" that was then transmitted back to all of the ships and displayed on plan-position indicators similar to radar displays. Commanders could then see information from everywhere, not just their own ship's sensors.
Development on DATAR was started by the Royal Canadian Navy in partnership with Ferranti Canada (later known as Ferranti-Packard) in 1949. The system proved too costly for the post-war Navy to develop alone, and when the Royal Navy and the United States Navy declined to share in the program it was ended. Both would then go on to start development of similar systems to fill this same role, the RN's Comprehensive Display System and the USN's Naval Tactical Data System.
In 1948, the Canadian Defence Research Board (DRB) sent a letter to various Canadian electronics firms informing them of their intention to start a number of projects that would partner the military, academia and private companies. A copy of the letter was sent to Ferranti Canada, then a small distributor of Ferranti's United Kingdom electrical equipment. The letter was forwarded to the then-CEO of Ferranti in the UK, Vincent Ziani de Ferranti, who became excited at the prospect of enlarging their Canadian operations largely funded by the government. At a meeting in October 1948 de Ferranti was disappointed to learn that while the DRB was equally excited, the amount of money they had to offer was basically zero.
DATAR is a computerized battlefield information system.

Method may refer to:
Method, Inc. is an international experience design firm with offices in San Francisco, New York, and London.
Method is an international experience design firm focused at the intersection of brand, product, and service design. Method was created in 1999 by Kevin Farnham, David Lipkin, Patrick Newbery, Mike Abbink, and Meng Mantasoot. First started in San Francisco, Method's founding principle was to use multidisciplinary, multi-platform design thinking to create beautiful and extendable solutions. Method's goal was to be quick to adapt to new technology. Method has approximately 100 employees in 3 offices located in San Francisco, New York, and London.
In 1999, the opportunity to work together with Autodesk arose, launching Method. In 2000, Method expanded and opened its New York office in order to accommodate more work. Method's earliest clients were Autodesk, Adobe Systems, Gucci, Palm, MoMA, and Macromedia.
Their international presence was established in 2008 when Method opened its London office.
A method (or message) in object-oriented programming (OOP) is a procedure associated with an object class. An object is made up of behavior and data. Data is represented as properties of the object and behavior as methods. Methods are also the interface an object presents to the outside world. For example a window
object would have methods such as open
and close
. One of the most important capabilities that a method provides is method overriding. The same name (e.g., area
) can be used for multiple different kinds of classes. This allows the sending objects to invoke behaviors and to delegate the implementation of those behaviors to the receiving object. Method in java programming sets the behaviour of class object. For example an object can send an area
message to another object and the appropriate formula will be invoked whether the receiving object is a rectangle
, circle
, triangle
, etc.
Methods also provide the interface that other classes use to access and modify the data properties of an object. This is known as encapsulation. Encapsulation and overriding are the two primary distinguishing features between methods and procedure calls.
