What is a database?

  • Instead of storing the same data in many files, data can be structured (in tables) in a database, a collection of (usually) related data tables
  • When an application needs specific data it can be retrieved from the database
  • Example: Personnel, Sales, Accounting dept
  • Sometimes referred to as a Repository of facts

Information system

  • The database is part of a larger whole known as an Information System (IS).
  • The IS provides for data collection, storage, and retrieval.
  • It also facilitated the transformation of data into information and the management of both the data and the information.

Why use a database?

  • Data constitutes the building blocks of Information (Information is produced by processing data)
  • No decision activity should take place without information
  • Good, relevant and timely information is the key to good decision making
  • Good decision making is the key to organizational survival in a global environment

Database management

  • Database is shared, integrated computer structure housing:
    • End user data
    • Metadata

  • Database Management System (DBMS)
    • Manages Database structure
    • Controls access to data
    • Contains query language

Importance of DBMS

  • Makes data management more efficient and effective
  • Query language allows quick answers to ad hoc queries
  • Provides better access to more and better-managed data
  • Promotes integrated view of organization’s operations
  • Reduces the probability of inconsistent data

Historical roots of database

  • First applications focused on clerical tasks
  • Requests for information quickly followed
  • File systems developed to address needs
    • Data organized according to expected use
    • Data Processing (DP) specialists computerized manual file systems

What are Products?

A product is defined as:
“Anything that is capable of satisfying customer needs”

This definition includes both physical products (e.g. cars, washing machines, DVD players) as well as services (e.g. insurance, banking, private health care).

The process by which companies distinguish their product offerings from the competition is called branding. For most companies, brands are not developed in isolation – they are part of a product group.

A product group (or product line) is a group of brands that are closely related in terms of their functions and the benefits they offer (e.g. Dell’s range of personal computers or Sony’s range of televisions).

There are two main types of product brand:
(1) Manufacturer brands
(2) Own-label brands

Manufacturer brands are created by producers and use their chosen brand name. The producer has the responsibility for marketing the brand, by building distribution and gaining customer brand loyalty. Good examples include Microsoft, Panasonic and Mercedes.

Own-label brands are created and owned by distributors. Good examples include Tesco and Sainsbury’s.

The main importance of branding is that, done well, it permits a business to differentiate its products, adding extra value for consumers who value the brand, and improving profitability for the company.

Businesses should manage their products carefully over time to make sure that they deliver products that continue to meet customer wants. The process of managing groups of brands and product lines is called portfolio planning.

Two models of product portfolio planning are widely known and used in business:

  • The Boston Group Growth-Share Matrix, and
  • GE Market Attractiveness model

Businesses need to regularly look for new products and markets for future growth. A useful way of looking at growth opportunities is the Ansoff Growth matrix which suggests that there are four main ways in which growth can be achieved through a product strategy:

  1. Market penetration – Increase sales of an existing product in an existing market
  2. Product development – Improve present products and/or develop new products for the current market
  3. Market development – Sell existing products into new markets (e.g. developing export sales)
  4. Diversification – Develop new products for new markets
