The front-end application or data access layer may request schema information, called metadata, along with the data when querying SQL Server. Typically, SQL Server will return schema information for the underlying tables, but the VIEW_METADATA option tells SQL Server to return schema information about the view, rather than the tables referenced by the view. This prohibits someone from learning about the table s schema and is useful when the view s purpose is to hide sensitive columns.

that circuitry is provided on a paper-phenolic PCB and transistors are used instead of sophisticated integrated circuits. The more primitive the radio, the better the diagnostic tool. It is nearly impossible to locate the exact source of RF energy (component pin or trace) due to the broadband nature of the pocket radio. Radios are a quick method of locating leaks in seams of chassis-and-cable assemblies. If lucky enough, the exact problem area can be identified and remedial measures taken, such as patching up an enclosure seam with copper tape, placing a ferrite core over a cable, or rerouting cable harness assemblies. The advantage of using an AM/FM radio lies in its simplicity and availability. It is difficult to transport test instrumentation onto a manufacturing floor or a customer site (when they report an EMC event). Anyone is capable of locating problem areas and applying a quick fix. The magnitude of emissions minimized by a quick fix cannot be ascertained; however, if the audio volume of the interference is lower, chances are that one has isolated the leak point. From here, an experienced EMC engineer can proceed to the exact area that drives or stimulates the propagation path. A disadvantage of using an AM/FM radio is that the output of a pocket radio only provides an indication of the modulation present on the waveform on speaker. For EMC analysis, we are generally interested in the frequency and magnitude of the RF signal. When we tune in to the harmonic of a digital clock, detection may only occur by the way the radio squelches background noise, or reduces the amplitude of legitimate radio transmissions. Broadband Field Sensors. Broadband field sensors are useful for on-site diagnostic purposes to determine if a problem exists with compatibility between systems or units. Several different types of sensors are available. The most common use of these probes is in anechoic chambers. The specialized broadband probes in chambers ascertain if the field intensity is uniform across the EUT. These sensors are not useful for diagnosing or troubleshooting EMI, as they are designed to detect very strong levels of intentionally generated RF energy. What are of value to engineers or technicians are portable hand-held field sensors (Figure 5.30). Most broadband field sensors indicate only the total field strength of a signal without providing frequency information. The antenna is usually a tiny dipole or magnetic loop in three orthogonal axes, thus providing the combination of all polarizations of the fields being measured. The antenna feeds a wideband detector and an amplifier to indicate field strength. Depending on the vendor, broadband field sensors measure electric, magnetic, or electromagnetic fields. Each probe operates over a specific range of frequencies. Calibrated data may be recorded to ascertain if a solution (rework) is effective. A useful application for a field sensor is in an industrial or commercial environment to locate sources of strong magnetic fields from AC mains transformers (that provide power to the building), which may affect video monitors located nearby. In hospitals and other controlled environments, a magnetic resonance imaging (MRI) machine, for example, can cause serious malfunction of life support monitoring

Convergence is de ned as the moving toward union or one another. In the context of the information superhighway, revolution, evolution, or whatever you choose to call it, the concept of convergence cuts across a number of dimensions, including a wide range of applications and the underlying technologies. In full form, convergence represents the coming together of every technology and application discussed in the previous 13 chapters. 14.1.1 Applications
