Locking is the act of putting a lock (access restriction) on an aspect of a database which at a particular given instance is being modified.

Feature Locking: Method for preventing a second user from editing a feature while the original user is performing an edit. Locking prevents writing on a feature by others while a feature or record is currently "checked out" for modification.

database lockLocking is a mechanism by which database systems can prevent conflicting access to data when multiple users are making requests to the data. See also persistent lock.

Bentley Map supports direct two-tier editing of standard Oracle Spatial databases employing a feature locking mechanism for multi-user environments.

In this paper I have tried to stress several general and interlocking themes.

Location is key to unlocking the potential of location-based advertising, marketing, and analytics. With Wi-Fi location set to become ubiquitous it is a vital technology to support, ABI Research said.

chert -- Hard, dense sedimentary rock, composed of interlocking quartz crystals and possibly amorphous silica (opal). The origin of the silica is normally biological, from diatoms, radiolaria or sponge spicules. Synonymous with flint.

You can increase the physical security of computers by locking doors and installing intruder, fire, and water detection systems.

pegmatite An extremely coarse-grained igneous rock with interlocking crystals, usually with a bulk chemical composition similar to granite but commonly containing rare minerals enriched in lithium, boron, fluorine, niobium, ...

The Moon's gravitation is the cause of the tides on Earth. The same effect has lead to its tidal locking: its rotation period is the same as the time it takes to revolve around the Earth, meaning it always presents the same face to the planet.

However, VE extends the business model to fully integrate the visualization tool into Microsoft's Office suite. This added boost beyond just eyeball-locking software brings VE closer to GIS-like utility …beyond mapping per se.

GPS uses a constellation of 24 satellites in precise orbits approximately 11,000 miles above the earth. The satellites transmit data via high frequency radio waves back to Earth and, by locking onto these signals, ...
