Transaction Processing SystemA transaction processing system is a type of information system. TPSs collect, store, modify, and retrieve the transactions of an organization. A transaction is an event that generates or modifies data that is eventually stored in an information system. To be considered a transaction processing system the computer must pass the ACID test. The essence of a transaction program is that it manages data that must be left in a consistent state. E.g. if an electronic payment is made, the amount must be both withdrawn from one account and added to the other; it cannot complete only one of those steps. Either both must occur, or neither. In case of a failure preventing transaction completion, the partially executed transaction must be 'rolled back' by the TPS. While this type of integrity must be provided also for batch transaction processing, it is particularly important for online processing: if e.g. an airline seat reservation system is accessed by multiple operators, after an empty seat inquiry, the seat reservation data must be locked until the reservation is made, otherwise another user may get the impression a seat is still free while it is actually being booked at the time. Without proper transaction monitoring, double bookings may occur. Other transaction monitor functions include deadlock detection and resolution (deadlocks may be inevitable in certain cases of cross-dependence on data), and transaction logging (in 'journals') for 'forward recovery' in case of massive failures.
Transaction Processing is not limited to application programs. The 'journaled file system' provided with IBMs AIX Unix operating system employs similar techniques to maintain file system integrity, including a journal.

Contrasted with batch processing

Batch processing is not transaction processing. Batch processing involves processing several transactions at the same time, and the results of each transaction are not immediately available when the transaction is being entered;[1] there is a time delay. Transactions are accumulated for a certain period (say for day) where updates are made especially after work.

Real-time and batch processing

There are a number of differences between real-time and batch processing. These are outlined below:
Each transaction in real-time processing is unique. It is not part of a group of transactions, even though those transactions are processed in the same manner. Transactions in real-time processing are stand-alone both in the entry to the system and also in the handling of output.
Real-time processing requires the master file to be available more often for updating and reference than batch processing. The database is not accessible all of the time for batch processing.
Real-time processing has fewer errors than batch processing, as transaction data is validated and entered immediately. With batch processing, the data is organised and stored before the master file is updated. Errors can occur during these steps.
Infrequent errors may occur in real-time processing; however, they are often tolerated. It is not practical to shut down the system for infrequent errors.
More computer operators are required in real-time processing, as the operations are not centralised. It is more difficult to maintain a real-time processing system than a batch processing system.

Marketing Information SystemsIntroduction
Marketing was the first functional area to exhibit an interest in MIS
The marketing information system has three subsystems; the accounting information system (AIS), marketing research, and marketing intelligence
Functional information systems: the conceptual systems should be "mirror images" of the physical systems

Marketing Principles
  • Marketing mix
  • Product
  • Promotion
  • Place
  • Price
The Marketing Information System (MKIS)
Kotler's marketing nerve center
3 information flows
  • Internal
    • Gathered in firm
  • Intelligence
    • From environment
  • Communications
    • To environment
Marketing Information System (MKIS) Definition
    A computer-based system that works in conjunction with other functional information  systems to support the firm's management in solving problems that relate to marketing the firm's products.
An MKIS Model
1. Output
  • Product
  • Place
  • Promotion
  • Price
  • Integrated mix
2. Database
3. Input

  • *AIS
  • *Marketing research
  • *Marketing intelligence
*AIS (Accounting Information System)
  1. Sales order data is input.
  2. AIS provides data for
  • Periodic reports
  • Special reports
  • Mathematical models and knowledge-based models
*Marketing Research Subsystem1. Managers use marketing research to gather  information :
  • Gathered from customers and prospects
  • Purchased or procured from other organizations
2. Processed using marketing research subsystem
3. Primary and Secondary Data
4. Used by marketing research subsystem
5. Primary data are collected by the firm, Examples of primary data is:
  • Survey
  • In-depth interview
  • Observation
  • Controlled experiment
  • Primary and Secondary
Secondary data is:
  • Mailing lists
  • Retail sales statistics
  • Video retrieval systems
  • Some secondary must be bought and some is free
Marketing Research Software
  • Graphics packages (print maps)
  • Makes market research a reality for all firms
  • Statistical analysis
  • Expertise to interpret software outputs is the key to successful use of these tools
*Marketing Intelligence Subsystem
  • Ethical activities aimed at gathering information about competitors
  • Not to be confused with industrial espionage
  • Each functional information system has an intelligence responsibility
1. Sebut dan jelaskan bagian dari Marketing Information System?
2. Jelaskan prinsip-prinsip marketing?
3. jelaskan satu saja sebuah software yang digunakan untuk melakukan analiasa atau riset pasar?

Pertemuan 5

Decision Support Systems
Sistem Penunjang Keputusan

Simon’s Types of Decisions
Programmed decisions
repetitive and routine
have a definite procedure

Nonprogrammed decisions
Novel and unstructured
No cut-and-dried method for handling problem

Simon’s Problem Solving Phases
Searching environment for conditions calling for a solution
Inventing, developing, and analyzing possible courses of action
Selecting a course of action from those available
Assessing past choices

Definitions of a Decision Support System (DSS)
General definition - a system providing both problem-solving and communications capabilities for semistructured problems
Specific definition - a system that supports a single manager or a relatively small group of managers working as a problem-solving team in the solution of a semistructured problem by providing information or making suggestions concerning specific decisions.

The DSS Concept
Gorry and Scott Morton coined the phrase ‘DSS’ in 1971, about ten years after MIS became popular
Decision types in terms of problem structure
Structured problems can be solved with algorithms and decision rules
Unstructured problems have no structure in Simon’s phases
Semistructured problems have structured and unstructured phases

Three DSS Objectives
1. Assist in solving semistructured problems
2. Support, not replace, the manager
3. Contribute to decision effectiveness, rather than efficiency

1. Jelaskan definsi DSS secara umum dan khusus
2. Jelaskan tujuan dari DSS
3. Berikan contoh dari masalah terstruktur, semi terstruktur dan tidak terstruktur?
