Database Programming

A file system is necessary for a computer to work with files; however, a file system is not a physical object, and is pretty useless without a computer to use it on.

A byte is the smallest unit of addressable storage. Although a bit is smaller than a byte, a single bit cannot be addressed directly; we always deal with groups of bits and a byte is the smallest group of bits that can be physically addressed. However, once we have addressed a byte, we can then examine the individual bits within it using the bitwise logic operators (AND, OR, NOT and XOR).

On most systems a byte is exactly 8 bits in length. The reason for this is simply that we can represent any 8-bit value using a convenient two-digit hexadecimal notation, where each hex digit represents exactly 4-bits (often called a nybble because it is half-a-byte). Thus an 8-bit byte can be represented by any hexadecimal value in the range 0x00 to 0xff (or 0 to 255 decimal).

(Some systems use odd-size bytes, such as a 9-bit byte. For this we typically use 3-digit octal notation because an octal digit represents exactly 3 bits. Such systems are rare, but we sometimes come across other odd-sized bytes, especially in older data transfer systems such as dot-matrix printers which utilised a 7-bit byte. However, in modern architecture, we can safely say that a byte is always at least 8 bits long.)

Not all programming languages utilise a byte data type as such. C, for instance, doesn't have a built in byte data type but it does have a char data type which is always 1 byte in length. There's no real reason why there isn't a byte data type in C, but when all data types are measured in terms of bytes it was probably deemed unnecessary to say that a byte is 1 byte in length. Although a char is typically used to encode a single character from a character set (and has built in overloads specific to that purpose), the encoding is no less numeric than a byte would be, so there was no real need for a separate byte data type.

Although a single byte can represent any decimal value in the range 0 to 255, it is more correct to say that a single byte can represent any one of 256 unique abstractions. Whether it is a single character from a character set, an unsigned value in the range 0 to 256, or a signed value in the range -128 to +127, these are merely abstractions. How abstractions are interpreted is entirely down to the programmer and/or the programming language.

Manual filing is the process of actually handling a physical piece of data. In the days before computers, a person made a folder of data and kept it in a filing cabinet, alphabetized or according to category.

When the early computers came along, people then converted the data to a punch card system that was readable to the computer. These looked like envelopes but were made of a light cardboard and were loaded into a punch card reader in a stack. The reader then entered the data into the computer, the cards were removed, and and another pile put into the machine.

Aren't you glad that progress has been made in making computers work today?

manual system is a system involving data processing which does not make used of stored data, so it is hard to do programs like recording some data or information using this system because it may cause a wasting of time and losting some files, to overcome this problem you may use a computerized sysetm to work it easily.

Metamessages are the way men and women communicate with each other. It is the way they are receiving the message that leads it to the reaction. Example, women always say "Im fine" but in reality we are not okay, it just means we want our partner to discuss more into the situation but the problem is that not all men understand that and they will simply accept when the girl says "I'm fine"

From lowest to highest, the four levels of the organizational hierarchy are operational, knowledge, management, and strategic. Types of information systems include transaction processing systems, office systems, knowledge work systems, decision-support systems, management information systems, and executive support systems.

Transaction processing systems, such as order tracking, payroll, machine control, and compensation, serve the operational level. Engineering workstations, word processing, graphics workstations, managerial workstations, document imaging, and electronic calendars are examples of knowledge work systems and office systems that serve the knowledge level. Sales region analysis, cost analysis, annual budgeting, and relocation analysis are examples of decision-support systems and management information systems. Many of these systems are programs that students learn in their management science or quantitative methods courses. Some are based on database management systems. Examples of executive support systems that serve the strategic level are sales trend forecasting, operating plan development, budget forecasting, profit planning, and manpower planning.

A university has a large number of courses in catalog.Attributes of COURSE include Course_Number(identifier),Course_Name and Units.Each course may have one or more course as prerequisties or may have no prerequisties.Similarly,a particular course may be a prerequisties for any number of courses or may not be prerequities for any other course.

There are various factors affected company performance, particularly for multi national company. One classical answer is the company competitive forces as explained by Prof. Michael Porter Ph.D. The competitive forces includes the threat of new entrants, threat of substitution, bargaining power of suppliers and customers, as well as the intra industry competitiveness. This theory basically determines the market and industry environment setting in which the firm operates. The more recent literatures suggests that intra industry performance variations are due to recourse heterogeneity within the firms, which is also known as resource based view. Some resources uniqueness such as valuable, rare, imperfect immitability, and non substituteable gives competitive edge of the company. When the environment become more unpredictable, the company's ability to adapt determines the sustainability of company performance. Dynamic capability, that is the ability of company to learn and adapt to any situation, becomes key factors. Performance of multinational company are basically affected by both type of perspective: market and its own resources. Global industry environment will likely be the most important aspect for any MNC. The ability for MNC to stay global and yet be competitive locally will be the differentiating factor that makes the MNC to sustain in hard competition. Competitiveness locally, will be much determined by its resource specificity following the RBV. The MNC's ability to adapt is crucial. MNC headquater may become the driver for the dynamic capability, but also can be the source of rigidity. Headquarter, which normally thousands of miles away, most of the time forget that local environment has more significant impact to the business than the global one, as viewed by the headquarter.
