WEEK ONE

TOPIC: INTERNET

The word “INTERNET” stands for International Network simply put as NET. It comprises of all computers around the world, connected together to share resources and information irrespective of distance and/or geographical location. The Internet is a worldwide communication medium or pool from where people all over the world could exchange retrieve, disseminate and store information thus, turning the world into a global village. It is the use of internet that actually turns the world into a global village where users like government, military, educational and commercial institutions around the world become one. There is no person, company, government or country that can claim single ownership of the internet. The computers within the internet are connected via communication equipment including telephone lines i.e. wired or wireless, satellites etc.

 

WHAT IS INTERNET?

The internet, that is, International Network is an electronic means of communication via a computer network, whereby people all over the world can have access to information at any time in a matter of seconds. Information can be given to people all over the world to see and retrieve at the same time using computer and telephone. It is the fastest and the most reliable means of data and information transfer.

Internet is a worldwide communication medium where people all over the world can exchange, retrieve, disseminate and store information. No one person or organization owns the internet. It belongs collectively to the telecommunication companies.

WEEK SEVEN

TOPIC:
DATABASE

 

Database is an application that is used to store information in a structured way. It is a collection of records or data in an organized form.

 

A database is an organized collection of related information that allows the storage of different types of record with appropriate interconnections.

 

Databases are designed to offer an organized mechanism for storing, managing and retrieving information. Database operates through the use of tables.

 

CONCEPT OF DATABASE

The idea of database came as a result of how people keep files in an office cabinet. In the ancient time, there were no computers and most fillings and storing were done manually. This allows redundancy of data and time wastage.

 

Advantages of Database

  1. It enables file or document sharing
  2. It allows consistency of data.
  3. It saves time.
  4. No data redundancy.
  5. It allows full file access.

 

Disadvantages of Database

DATA BASE TERMINOLOGIES

  • Table: a table is the basic unit of a database. It is a collection of related data about a specific subject. The table is divided into rows and columns.
  • Field: this is an area reserved for each piece of individual data, such as student ID, No etc.
  • Record: A record is a group of related fields pertaining to one person, place or thing. Databases consist of records and each record represents one item in a database.
  • Key field: A key field or primary key is a field that uniquely identifies each record in a file. The data in a key field is unique to a specific record.
  • File: is a collection of related records. If you work with a computer, you are already working with files.

 

 

SUMMARY

  • Database is a collection of inter related files or tables.
  • File: is a collection of related records.

TOPIC: FORMS OF DATABASE.

 

There are various forms or ways by which database can be set up. They include:

  1. Flat file database
  2. Relational database
  3. Hierarchical database
  4. Network database
  5. Operational database
  6. Distributed database
  7. End user database

 

  1. FLAT FILE DATABASE

This is the traditional data file storage system ideal for storing small amounts of data that needs to be humanly readable or edited by hand. They are called flat because they contain only one table. The disadvantage is that flat files can be corrupted easily.

 

  1. RELATIONAL DATABASE

This is the most common of all the different types of database, files are organized in tables called relations. Each table has a key filed which is used to connect to other tables. Hence the tables are connected through several key fields.

 

  1. HIERARCHICAL DATABASE

This form of database has a tree-like structure. In this database, a single table acts as the root of the database from which other tables are connected. All windows operating system operate tree like database.

 

EVALUATION

  1. Mention the forms of database.
  2. Explain relational database

     

  3. NETWORK DATABASE

This database was designed to solve some of the more serious problems with hierarchical database model. Visually network database looks like hierarchical database.

 

  1. DISTRIBUTED DATABASE

This form of database is stored on different location connected by client/server network. Data that is been stored are transmitted through network. Each work group may have their own database and are connected through network.

 

EXAMPLES OF DATABASE

  1. Microsoft Access
  2. Microsoft SQL server
  3. Sybase
  4. FoxBASE
  5. Oracle
