Why have developers at places like Facebook and Twitter increasingly turned to graph databases to manage their highly connected big data? The short answer is that graphs offer superior speed and flexibility to get the job done.
It’s time you added skills in graph databases to your toolkit....
The team that brought you the bestselling Beginning iPhone 4 Development is back again for Beginning iOS 5 Development, bringing this definitive guide up-to-date with Apple's latest and greatest iOS SDK, as well as with the latest version of Xcode.
iPhone Location Aware Apps Beginner's Guide is probably the first book from any technical publisher that teaches you to build real world applications (five of them).

THE “CLOUD” IS ONE OF THE MOST tossed-around words these days in any IT conversation. But
what does it mean? And what are the implications of the cloud for SharePoint? In fact, there are
many implications for SharePoint with the cloud, ranging from extending existing solutions to use
code or services that are deployed to the...
While books and journals of high quality have proliferated in discrete and compu-
tational geometry during recent years, there has been to date no single reference
work fully accessible to the nonspecialist as well as to the specialist, covering all
the major aspects of both fields. The Handbook of Discrete and Computational
Geometry...
Where. Whether it refers to where you have been, where you are, or where you are
going, the concept of where is important. Where links data to the physical world. A
shopping list can be a very useful collection of data on its own, but that data can be
even more useful with more context. If you map the location of the stores needed for...
Event-based distributed systems are playing an ever increasing role in
areas such as enterprise management, information dissemination, finance,
environmental monitoring and geo-spatial systems. Event-based processing
originated with the introduction of Event-Condition-Action (ECA) rules to
database systems in the 1980s. Since then,...
In 1983 I left the International Institute for Aerospace Survey and Earth Sciences (ITC) and went to Wageningen Agricultural University, where I took the chair of “Land Surveying and Teledetection”. Up to that time I had been active mainly in geodesy and photogrammetry, but at Wageningen it soon became...
During the 1980's the flat relational model (relational model), which was initiated by
Codd in 1970, gained immense popularity and acceptance in the market place. One of
the main reasons for this success is that the relational model provides physical data
independences i.e. changing the physical organization of the database does not...
GeoComputation (GC) is a follow-on revolution that is occurring after the
introduction of geographical information systems (GIS). It is expected to gather
speed and momentum in the first decade of the 21st century. The rationale
behind this latest revolution is quite simple. When we have finished creating our
GIS databases, set up our...
The Web has changed our lives in many
ways. The first online, on-demand driving
directions from MapQuest very nearly rendered
traditional road atlases obsolete. Today,
many websites that provide driving directions also
make their maps available to developers. Using these
mapping APIs, you can plot your own points or...
Similar to many research and application fields, geography has moved from a datapoor and computation-poor to a data-rich and computation-rich environment. The scope, coverage, and volume of digital geographic datasets are growing rapidly. Public and private sector agencies are creating, processing, and disseminating digital data on land use,...
