An enterprise is a large organization, and an enterprise application is software that helps an organization solve business problems. Enterprise applications can be categorized by their customer visibility (upstream, downstream, business enabler), the industry and business functions they support, how they process data (OLTP, OLAP), whether they are custom-built or commercial, and if they are host-centric or distributed. They must enhance efficiency, ensure security, handle large data volumes, and be easily maintained. Challenges for enterprise applications include automating business processes, integrating applications, maintaining security, and providing rich user experiences.

7. CATEGORIES OF ENTERPRISE APPLICATION
1) From visibility to Customers
1.1 Upstream or Customer facing enterprise
applications
1.2 Downstream or Back end enterprise applications
1.3 Business Enabler enterprise applications
7

8. 1.1 UPSTREAM ENTERPRISE APPLICATION
 The applications which are front end systems of an
organization known as upstream enterprise
applications.
 Also known as Customer facing enterprise
application.
 For Example
“order capture” application that captures online orders
of customers is an upstream enterprise application.
8

9. 1.2 DOWNSTREAM ENTERPRISE APPLICATION
 Applications that work behind of the scenes in an
organization to fulfill the customers or end users
needs are known as downstream enterprise
applications.
 For Example
“order provisioning” which helps in fulfill and
provisioning the online orders captured through
“order capture” upstream enterprise application.

10. 1.3 BUSINESS ENABLER ENTERPRISE
APPLICATION
 The applications that fulfill the general organization
needs are known as Business enabler enterprise
applications.
 For Example
Payroll System
Human Resource Management

12. CATEGORIES OF ENTERPRISE APPLICATION
(CONTD…)
2) Industry they cater to
Example Billing System for telecom is different from
billing system in retail industry
3) Enterprise business functions they fulfill
For example, order management or order fulfillment
application
4) Nature of processing
For example, batch processing, online analytical
processing (OLAP), online transaction
processing(OLTP) or Decision Support System (DSS)
5)Customers built or readymade commercial off the shelf
packages
6) Host centric or Distributed Application 12

13. OLTP
 OLTP (On-line Transaction Processing) deals with
operational data, which is data involved in the operation
of a particular system and it is characterized by a large
number of short on-line transactions (INSERT, UPDATE,
and DELETE).
 The main emphasis for OLTP systems is put on very fast
query processing, maintaining data integrity in multi-
access environments and an effectiveness measured by
number of transactions per second.
 Example: In a banking System, you withdraw amount
through an ATM. Then account Number, ATM PIN
Number, Amount you are withdrawing and Balance
amount in account are operational data elements. 13

14. OLAP
 An OLAP (On-line Analytical Processing) deal
with Historical Data or Archival Data, and it is
characterized by relatively low volume of
transactions. In addition, the Queries needed for
these systems are often very complex and involve
aggregations as for OLAP systems the response
time is an effectiveness measure.
 Example: If we collect last 10 years data about flight
reservation, the data can give us much meaningful
information such as the trends in reservation.
