Database Programming

1. Program-Data Dependence. File descriptions are stored within each application program that accesses a given file.
2. Duplication of Data. Applications are developed independently in file processing systems leading to unplanned duplicate files. Duplication is wasteful as it requires additional storage space and changes in one file must be made manually in all files. This also results in loss of data integrity. It is also possible that the same data item may have different names in different files, or the same name may be used for different data items in different files.
3. Limited data sharing. Each application has its own private files with little opportunity to share data outside their own applications. A requested report may require data from several incompatible files in separate systems.
4. Lengthy Development Times. There is little opportunity to leverage previous development efforts. Each new application requires the developer to start from scratch by designing new file formats and descriptions
5. Excessive Program Maintenance. The preceding factors create a heavy program maintenance load.
6. Integrity Problem. The problem of integrity is the problem of ensuring that the data in the database is accentuate.

Relational Database

A single-valued attribute is one that can have only one value. For example, a person has only one first name and only one social security number. A simple attribute is one that cannot be decomposed into its component pieces. For example, a person's sex is classified as either M or F and there is no reasonable way to decompose M or F. Similarly, a person's first name cannot be decomposed into meaningful components. (In contrast, if a phone number includes the area code, it can be decomposed into the area code and the phone number itself. And a person's name may be decomposed into a first name, an initial, and a last name.)

Single-valued attributes are not necessarily simple. For example, an inventory code HWPRIJ23145 may refer to a classification scheme in which HW indicates HardWare, PR indicates Printer, IJ indicates InkJet, and 23145 indicates an inventory control number. Therefore, HWPRIJ23145 may be decomposed into its component parts... even though it is single-valued. To facilitate product tracking, manufacturing serial codes must be single-valued, but they may not be simple. For instance, the product serial number TNP5S2M231109154321 might be decomposed this way:

TN = state = Tennessee

P5 = plant number 5

S2 = shift 2

M23 = machine 23

11 = month, i.e., November

09 = day

154321 = time on a 24-hour clock, i.e., 15:43:21, or 3:43 p.m. plus 21 seconds

Accessibility to education is one of the main advantages to present day education.In the past education was only for the wealthy.The poor were not given an opportunity to improve their lot in life.Females were also denied an education by virtue of the "fact" they would get married and so an education would be "wasted" on females.As North America was settled children were pulled from schools during the harvesting season or as needed ,to work the farm.Summers off were no vacation period for students, it was a time to help with farm work instead of hiring farm hands.Children in most, if not all developing countries have mandatory education for all children, regardless of their abilities .In the past children with special needs were hidden away and forgotten.Society ,in general tries to encourage developing nations to provide even basic education for its people.Modern society recognizes the importance of education.Today we realize that an education translates into opportunity and hope for the future.The ability to get an education, to foster creativity and curiosity, to seek answers will allow mankind to continue to grow. Today we try to encourage all children to reach for their fullest potential.Teachers are better qualified.No longer can a child , barely in their teens, become a teacher.The one room classroom is fortunately a thing of the past.The computor, libraries and ready access to information have all contributed to the ability to learn outside of the traditional classroom.On line and distance education have changed the face of what a classroom is.I'm glad that I was born when I was and am thankful my children and grandchildren will have more opportunities in life due to the fact they are able to get a good education.

Any information system will make use of the following physical components:

a) Hardware: The equipment and devices for inputting, outputting, secondary storage, processing as well as communications in the system.

b) Software: The set of programmes to facilitate processing procedures; it includes systems software, applications software and the model base.

c) Data Base: The organisational data to be used by various software programmes is usually stored in the form of files and database on the physical storage media such as computer tapes, disc drives, floppy diskettes.

d) Procedures: The operating procedures documented in the form of physical manuals constitute an important part of MIS components. These documents could be divided into three major types: Operating Manuals, User Manuals, and Systems Manuals.

e) Operating Personnel: The manpower operating these information systems include systems managers, systems analysts, data administrators, programmes, data entry and computer operators.

Processing Functions

The major processing functions in information systems include the following:

a) Processing of business transactions: To capture, collect, record, store and process the events of business interest, so that their effect should be carried over to the organisational performance records.

b) Updation of master files: The effect of these transactions is carried over to the status files of the organisational performance. Master files at any given time shall reflect the status of any entity after having incorporated the impact of up-to-moment transactions.

c) Generation of information reports: After having processed the transactions and updation of master files, the information reports are generated so as to assist the managers in their decision-making.

d) Processing of interactive enquiries: On-line information processing systems provide the facility of responding to the business queries raised by managers on the data files - both master as well as transaction files.

The main implicit properties of a database are listed below:

1. A database represents some aspect of the real world, sometimes called

the miniworld or universe of discourse (UoD). Changes to the miniworld

are reflected in the database.

2. A database is a logically coherent collection of data with some inherent

meaning.

3. A database is designed, built, and populated with data for a specific

purpose.

Skoda able to identify Brand Position was one of the weakness for Skoda in the highly competitive fragmented market by positioning the brand as low budget or low quality vehicles which caused Skoda to get 1.7% of the market share, because the company used to manufacture cars of poor image of quality, design, assembly, and materials, which leaded customers to perceive the brand image as poor image for majority consumers compare to other competitors like Ford, Peugeot, and Renault. By looking business model, example General Electric business model that say business organisation can determine its self by looking factors like Business Strengths (strong or average or weak) in the market and industry attractiveness (high or medium or low) at that market. According to that model that means the Skoda had probably weak business strength and its industry attractiveness was probably strong in the market.

The analysis gave clear direction to Skoda that there is need to Partnership with Volkswagen by raising strategic alliance between themselves which leaded the Skoda to change the negative image in the market. Also Skoda management did understood that they need to correct old perceptions by stop being defensive in promotional campaigns and change market message as Skoda owners need to be happy and contented with their cars, Also convincing users that Skoda cars were great to own and drive.

provides information that organizations require to manage themselves efficiently and effectively.Management information systems are typically computer systems used for managing. The five primary components: 1.) Hardware,2.) Software,3.) Data (information for decision making), 4.) Procedures (design,development and documentation), and 5.) People (individuals, groups, or organizations). Management information systems are distinct from other information systems because they are used to analyze and facilitate strategic and operational activities.

For example:

SELECT columnName FROM tableName WHERE columnName BETWEEN '1' AND '20'
