Conveying the decision to and gaining commitment
from those who will carry out the decision.

14. Styles of decision making:
Decision making style proposes people differ along
two dimensions in the way they approach decision
making. The first is an individual way of thinking.
The other dimension describes
anindividuals tolerance for ambiguity.
# decision making styles of four types.

15. 1) Directive Style: Managers using directive style have
low tolerance for ambiguity and are rational in their
way of thinking. They are efficient and logical.
(2) Analytic Style: Managers with an analytic style have
high tolerance for ambiguity than do directive type and
are rational in their way of thinking.
(3) Conceptual Style: Managers with conceptual style
have high tolerance for ambiguity and an intuitive way
of thinking.
(4) Behavioral Style: Managers with behavioral style
have low tolerance and an intuitive way of thinking.

16. Types of decision making:
Decision making have six types:
1. Programmed and non programmed
decisions: Programmed decisions are those which are
normally repetitive in nature and are taken as a routine
job and responsibilities.
2. Major and minor decisions: among different
decisions some decisions are considerably more
important than others and are prioritized.
3. Routine and strategic decisions: Routine
decisions are those decisions which are considered as

employee is involved in decision making it is called
individual decision.
6. Policy and operating decisions: Policy decisions

The slides for this text are organized into chapters. This lecture covers Chapter 1, and is an overview of database systems. The material is standard, with one exception: The discussion of transactions, concurrency control, and recovery is perhaps more in-depth than usual in a first lecture, and this deserves some explanation.
Students will (in typical course sequences) not be exposed to this material until much later in the course, and I find it useful for them to have a little background knowledge. This helps, for instance, when explaining why a buffer manager needs to support selective forcing of pages (because write-ahead logging requires it). It is also an important and engaging topic that draws students into the subject immediately. Sometimes, the interactions go so far that I move up the overview material on CC and recovery from Chapter 16, and cover it as Lecture 2! (Note that this can be readily done since Chapter 16 does not rely on any intervening chapters.)
