4 Elaborate the relationship between GIS , KMS,EIS 12 1 K2

Geographic information system (GIS) is a system designed to capture, store, manipulate,

analyze, manage, and present spatial or geographic data. The acronym GIS is sometimes used

for geographic information science (GIScience) to refer to the academic discipline that studies

geographic information systems[and is a large domain within the broader academic discipline

of geo informatics.

GIS can refer to a number of different technologies, processes, and methods. It is attached to

many operations and has many applications related to engineering, planning, management,

transport/logistics, insurance, telecommunications, and business. For that reason, GIS

and location intelligence applications can be the foundation for many location-enabled services

that rely on analysis and visualization

Knowledge management systems refer to any kind of IT system that stores and

retrieves knowledge, improves collaboration, locates knowledge sources, mines repositories

for hidden knowledge, captures and uses knowledge, or in some other way enhances the KM

process.

If my explanation above makes the definition of these systems seem vague, that is because

there is no consensus as to what constitutes a knowledge management system, much like there

is no consensus regarding KM. Furthermore, since KM is involved in all areas of the firm,

drawing a line is very difficult.

Executive information system (EIS), also known as an executive support system (ESS) is a

type of management information system that facilitates and supports senior executive

information and decision-making needs. It provides easy access to internal and external

information relevant to organizational goals. It is commonly considered a specialized form

of decision support system (DSS).

EIS emphasizes graphical displays and easy-to-use user interfaces. They offer strong reporting

and drill-down capabilities. In general, EIS are enterprise-wide DSS that help top-level

executives analyze, compare, and highlight trends in important variables so that they can

monitor performance and identify opportunities and problems. EIS and data

warehousing technologies are converging in the marketplace.

5 What is Prototyping? And discuss the strength and weakness of Prototyping. 12 1 K2

The Prototyping Model is a systems development method (SDM) in which aprototype (an

early approximation of a final system or product) is built, tested, and then reworked as

ecessary until an acceptable prototype is finally achieved from which the complete system or

product can now be developed.

E.G.S. PILLAY ENGINEERING COLLEGE (An Autonomous Institution, Affiliated to Anna University, Chennai)

Nagore Post, Nagapattinam – 611 002, Tamilnadu.

Encourages innovation and flexible designs.

Provides quick implementation of an incomplete, but functional, application

Weakness

Approval process and control is not strict.

Incomplete or inadequate problem analysis may occur whereby only the most obvious

and superficial needs will be addressed, resulting in current inefficient practices being

easily built into the new system.

Requirements may frequently change significantly.

Identification of non-functional elements is difficult to document.

Designers may prototype too quickly, without sufficient up-front user needs analysis,

resulting in an inflexible design with narrow focus that limits future system potential.

6 Describe about Geographic information system. 12 1 K2

4 Describe about HDBMS with example. 12 1 K2

A hierarchical database model is a data model in which the data is organized into a tree-like

structure. The data is stored as records which are connected to one another through links. A

record is a collection of fields, with each field containing only one value. The entity type of a

record defines.

The hierarchical database model mandates that each child record has only one parent, whereas

each parent record can have one or more child records. In order to retrieve data from a

hierarchical database the whole tree needs to be traversed starting from the root node. This

5 Explain the various steps of query processing and describe the SQL command 12 1 K2

steps of query processing

1. Parsing and translation

Translate the query into its internal form. This is then translated into relational

algebra. Parser checks syntax, verifies relations.

2. Optimization

Amongst all equivalent evaluation plans choose the one with lowest cost. Cost

is estimated using statistical information from the database catalog.

3.Evaluation

The query-execution engine takes a query-evaluation plan, executes that plan,

and returns the answers to the query. A relational algebra expression may have

4 Explain the Characteristics Cloud computing 12 1 K2

Agility improves with users' ability to re-provision technological infrastructure resources.

Application programming interface (API)

Cost reductions claimed by cloud providers. A public-cloud delivery model converts capital

expenditure to operational expenditure. This purportedly lowers barriers to entry, as

infrastructure is typically provided by a third party and does not need to be purchased for

onetime or infrequent intensive computing tasks.

Device and location independence enable users to access systems using a web browser

regardless of their location or what device they use (e.g., PC, mobile phone). As

infrastructure is off-site (typically provided by a third-party) and accessed via the Internet,

users can connect from anywhere.

Maintenance of cloud computing applications is easier, because they do not need to be

installed on each user's computer and can be accessed from different places.

Multitenancy enables sharing of resources and costs across a large pool of users thus

allowing for:

Centralization of infrastructure in locations with lower costs (such as real estate,

electricity, etc.)

peak-load capacity increases (users need not engineer for highest possible load-levels)
