Even the earliest business computer systems were used to process business records and produce information. They were generally faster and more accurate than equivalent manual systems. These systems stored groups of records in separate files, and so they were called file processing systems. Although file processing systems are a great improvement over manual systems, they do have the following limitations:
Data is separated and isolated.
Data is often duplicated.
Application programs are dependent on file formats.
It is difficult to represent complex objects using file processing systems. Data is separate and isolated. Recall that as the marketing manager you needed to relate sales data to customer data. Somehow you need to extract data from both the CUSTOMER and ORDER files and combine it into a single file for processing. To do this, computer programmers determine which parts of each of the files are needed. Then they determine how the files

Thermographic camera or what is called FLIR, Forward Looking Infrared, is type of cameras which produces an image with the use of infrared radiations or wavelength that differs from the common cameras which use the visible light.
How do thermal cameras work? Since it depends on the wavelength, its necessary to know a bit about the radiations produced by objects. Each object produces a certain amount of black bodies. From its name we can guess that it absorbs the electromagnetic radiation falling on it.
It is black because it cannot reflect or even transmit these radiations, which make the object black when it becomes cold. So, it is the cameras job to detect these radiations, since, the more temperature the object is, the more production of infrared radiation of black bodies. It is the same process done by a usual camera that handles visible light.
