Data modelA data model is an abstract model that organizes elements of data and standardizes how they relate to one another and to the properties of real-world entities. For instance, a data model may specify that the data element representing a car be composed of a number of other elements which, in turn, represent the color and size of the car and define its owner. The corresponding professional activity is called generally data modeling or, more specifically, database design.
Geographic information systemA geographic information system (GIS) consists of integrated computer hardware and software that store, manage, analyze, edit, output, and visualize geographic data. Much of this often happens within a spatial database, however, this is not essential to meet the definition of a GIS. In a broader sense, one may consider such a system also to include human users and support staff, procedures and workflows, the body of knowledge of relevant concepts and methods, and institutional organizations.
LandlineA landline (land line, land-line, main line, fixed-line, and wireline) is a telephone connection that uses metal wires from the owner's premises sometimes referred to as: "Pots", Twisted pair, telephone line, public switched telephone network or Bell System for transmissions.
Portable data terminalA portable data terminal, or shortly PDT, is an electronic device that is used to enter or retrieve data via wireless transmission (WLAN or WWAN). They have also been called enterprise digital assistants (EDA), data capture mobile devices, batch terminals or just portables. They can also serve as barcode readers, and they are used in large stores, warehouses, hospitals, or in the field, to access a database from a remote location. Others have a touch screen, IrDA, Bluetooth, a memory card slot, or one or more data capture devices.
InclinometerAn inclinometer or clinometer is an instrument used for measuring angles of slope, elevation, or depression of an object with respect to gravity's direction. It is also known as a tilt indicator, tilt sensor, tilt meter, slope alert, slope gauge, gradient meter, gradiometer, level gauge, level meter, declinometer, and pitch & roll indicator. Clinometers measure both inclines and declines using three different units of measure: degrees, percentage points, and topos.
