What Is Data Integrity, and What Are the Qualities of Valuable Information? Because data is used to generate information, many organizations realize that data is one of their more valuable assets. Data integrity identifies the quality of data. Data integrity is important because computers and people use information to make decisions and take actions. For a computer to produce correct information, the data that is entered in a database must have integrity. For information to be valuable, it should be accurate, verifiable, timely, organized, accessible, useful, and cost-effective. Accurate information is error free. Verifiable information can be proven as correct or incorrect. Timely information has an age suited to its use. Organized information is arranged to suit the needs and requirements of the decision maker. Accessible information is available when the decision maker needs it. Useful information has meaning to the person who receives it. Cost-effective information should give more value than it costs to produce.
At a point in a saturated normally consolidated clay layer the soil is subject to an in-situ vertical effective stress of 50kPa. The soil at the point has a moisture content of 44% and a compression index of 0.45. The effective stress at the point is..
The "U"-tube manometer containing mercury of density 13600 kg/cubic meters is used to measure the pressure drop along a horizontal pipe.
Given: Q = 1000gpm, total head = 140 feet, pump efficiency = 70 percent, motor efficiency 65 percent, cost of electricity = 5 cent per kilowatt hour. What would be the daily cost of electricity to operate a pump 24 hours per day
Before the second particle catches the first particle, what is the maximum distance between the two particles.
The 25-kg rectangular access door is held in the 90° open position by the single prop CD. Determine the force F in the prop and the magnitude of the force normal to the hinge axis AB in each of the small hinges A and B
A circulatr concrete column with a diameter of 8" has spiral reinforcing. Find the capacity of the column with 1% reingforcement. Find the capacity of the column with 8% reinforcement.
A sphere L ft in diameter is moving horizontally at a depth of 12 ft below a water surface where the water temperature is 50°F. v max = 1.5 V0. where V0. is the free stream velocity and occurs at the maximum sphere width.
Is it realistic to assume that no OH will be present in the equilibrium mixture?
A circular hatch, 2-m in diameter has its top 10-feet under water ( fresh water s.g. = 1.0), and is hinged on the bottom, and held closed on the top with a single bolt. Perform a moment balance about the hinge
The construction of a multi storied building started in January 1989 & was completed in June 1990. The total consolidation settlement of the building was estimated to be 8 cm.
The de-carburization of a steel can also be described by the error fuction. Starting with the equation, (cx-c0)/(sc-c0) = 1-erf(x/(2*(sqrt(Dt)))), and taking cs=0 derive an expression to describe the concentration profile of carbon as it diffuses out..
Split up the structure shown as appropriate and use the tabulated solutions to derive expressions for the horizontal and vertical deflections at point C. The bending stiffness is EI.
