Transaction Process System (TPS) is an information processing system for business transactions involving the collection, modification and retrieval of all transaction data. Characteristics of a TPS include performance, reliability and consistency.

TPS is also known as transaction processing or real-time processing.

A transaction process system and transaction processing are often contrasted with a batch process system and batch processing, where many requests are all executed at one time. The former requires the interaction of a user, whereas batch processing does not require user involvement. In batch processing the results of each transaction are not immediately available. Additionally, there is a delay while the many requests are being organized, stored and eventually executed. In transaction processing there is no delay and the results of each transaction are immediately available. During the delay time for batch processing, errors can occur. Although errors can occur in transaction processing, they are infrequent and tolerated, but do not warrant shutting down the entire system.

To achieve performance, reliability and consistency, data must be readily accessible in a data warehouse, backup procedures must be in place and the recovery process must be in place to deal with system failure, human failure, computer viruses, software applications or natural disasters.

Features of Transaction Processing System

There are several features involved in a good transaction processing system. A few of these critical features are described below.

1. Performance

The concept behind the use of TPS is to efficiently generate timely results for transactions. Effectiveness is based on the number of transactions they can process at a particular time.

2. Continuous availability

The transaction processing system should be a very stable and reliable system that must not crash easily. Disruption of TPS in an organization can lead to work disturbance and financial loss.

3. Data integrity

The TPS must maintain the same method for all transactions processed, the system must be designed to effectively protect data and overcome any hardware/ software issues.

4. Ease of use

The TPS should be user-friendly in order to encourage the use and also decrease errors from inputting data. It should be structured in such a way that it makes it easy to understand as well as guarding users against making errors during data-entry.

5. Modular growth

The TPS hardware and software components should be able to be upgraded individually without requiring a complete overhaul.

6. Controlled processing

Only authorized personnel, staff members, or employees should be able to access the system at a time.

Types of Transaction Processing Systems

1. Batch processing

Batch processing is when clusters of transactions are refined simultaneously using a computer system.

This method, although designed to be efficient for breaking down bulky series of programs, has a drawback as there is a delay in the transaction result.

2. Real-time Processing

Real-time processing carries out its transactions exclusively; this method ensures a swift reply on the condition of the transaction result. It is an ideal technique for dealing with singular transactions.

How does a Transaction Processing System Work?

1. Processing in a batch

Processing batch transactions requires data collection and batch grouping. Data collected are stored in the form of batches and may be processed anytime.  This long-established technique was used widely in the absence of infotech.

2. Processing in real-time

Recent technology innovations gave rise to real-time processing. RTP ensures instant data processing with the aim of providing a quick verification of the transaction. It is highly versatile as it can work effectively as a multi-user interface and can also be accessed anywhere there is an online network.

Components of Transaction Processing System

Below are some of the components involved in a TPS:

• Inputs: These are source documents gotten from transactions which serve as inputs into the computer’s accounting system examples are invoices, and customer orders.
• Processing: This requires the breaking down of information provided by the inputs.
• Storage: This is saved information in TPS memory, it may be in the form of ledgers.
• Output: Any generated record may serve as the output

Examples of Transaction Processing System

• TPS accumulates data about transactions and also initiates processing that transforms stored data. Examples include order processing, employee records, and hotel reservation systems.
• Batch transaction process examples include bill generation and check clearances.
• Examples of real-time transaction processes are the point of sale terminals (P.O.S) and microfinance loan systems.

Limitations of Transaction Processing Systems

• Managing operations with the TPS can be complicated if the company is not big enough to efficiently use the transaction processing system.
• TPS needs both hardware and software components to efficiently manage high data volume. This capacity makes TPSs susceptible to software security breaches in the form of the virus and faulty hardware issues such as power outage can disrupt the whole system.
• Effective integration of a TPS in a company operation requires skilled personnel, it also requires a link with associate company branches to maintain a secure flow of information. This high requirement can create instability and flux in the company’s daily operations.

Functions of Transaction Processing System

Transaction Processing Systems can execute input, output, storage, and processing functions.

(i) Input functions

This includes the securing of data on the source document, entering of input data in the system and also validate data.

(ii) Output functions

This includes the production of the report of the transaction via monitor or paper, examples are exception reports, detail reports, and summary reports.

(iii) Storage functions

This is the process by which data is stored. It entails the storage of information, accessing, sorting, and updating stored data.

(iv) Processing functions

This entails the transformation of data, it includes calculation, computation, and apt result.

Types of Recovery

• Backup Recovery: this can be used to reverse required changes to a record.
• Forward Recovery: this can be used to save transactions made between the last backup and the up to date time.it works by backing up a copy of the database and it is more proficient because it does not need to save each transaction.

A Transaction Processing System (TPS) is an infotech used to accumulate, store, modify and retrieve data transactions. Transaction processing systems present a unique response to user requirements, although planning to choose the most appropriate method relies heavily on the quantity of data and the type of business.

An information system (IS) is a formal, sociotechnical, organizational system designed to collect, process, store, and distribute information. In a sociotechnical perspective, information systems are composed by four components: task, people, structure (or roles), and technology.

A computer information system is a system composed of people and computers that processes or interprets information. The term is also sometimes used in more restricted senses to refer to only the software used to run a computerized database or to refer to only a computer system.

Information Systems is an academic study of systems with a specific reference to information and the complementary networks of hardware and software that people and organizations use to collect, filter, process, create and also distribute data. An emphasis is placed on an information system having a definitive boundary, users, processors, storage, inputs, outputs and the aforementioned communication networks.

Any specific information system aims to support operations, management and decision-making. An information system is the information and communication technology (ICT) that an organization uses, and also the way in which people interact with this technology in support of business processes.

Some authors make a clear distinction between information systems, computer systems, and business processes. Information systems typically include an ICT component but are not purely concerned with ICT, focusing instead on the end use of information technology. Information systems are also different from business processes. Information systems help to control the performance of business processes.

Alter argues for advantages of viewing an information system as a special type of work system. A work system is a system in which humans or machines perform processes and activities using resources to produce specific products or services for customers. An information system is a work system whose activities are devoted to capturing, transmitting, storing, retrieving, manipulating and displaying information.

As such, information systems inter-relate with data systems on the one hand and activity systems on the other. An information system is a form of communication system in which data represent and are processed as a form of social memory. An information system can also be considered a semi-formal language which supports human decision making and action.

Components of Information Systems

The computer age introduced a new element to businesses, universities, and a multitude of other organizations: a set of components called the information system, which deals with collecting and organizing data and information. An information system is described as having five components.

1. Computer hardware

This is the physical technology that works with information. Hardware can be as small as a smartphone that fits in a pocket or as large as a supercomputer that fills a building. Hardware also includes the peripheral devices that work with computers, such as keyboards, external disk drives, and routers. With the rise of the Internet of things, in which anything from home appliances to cars to clothes will be able to receive and transmit data, sensors that interact with computers are permeating the human environment.

2. Computer software

The hardware needs to know what to do, and that is the role of software. Software can be divided into two types: system software and application software. The primary piece of system software is the operating system, such as Windows or iOS, which manages the hardware’s operation. Application software is designed for specific tasks, such as handling a spreadsheet, creating a document, or designing a Web page.

3. Telecommunications

This component connects the hardware together to form a network. Connections can be through wires, such as Ethernet cables or fibre optics, or wireless, such as through Wi-Fi. A network can be designed to tie together computers in a specific area, such as an office or a school, through a local area network (LAN). If computers are more dispersed, the network is called a wide area network (WAN). The Internet itself can be considered a network of networks.

4. Databases and Data Warehouses

This component is where the “material” that the other components work with resides. A database is a place where data is collected and from which it can be retrieved by querying it using one or more specific criteria. A data warehouse contains all of the data in whatever form that an organization needs. Databases and data warehouses have assumed even greater importance in information systems with the emergence of “big data,” a term for the truly massive amounts of data that can be collected and analyzed.

5. Human Resources and Procedures

The final, and possibly most important, component of information systems is the human element: the people that are needed to run the system and the procedures they follow so that the knowledge in the huge databases and data warehouses can be turned into learning that can interpret what has happened in the past and guide future action.

Business information systems are sets of inter-related procedures using IT infrastructure in a business enterprise to generate and disseminate desired information.

Such systems are designed to support decision making by the people associated with the enterprise in the process of attainment of its objectives.

The business information system gets data and other resources of IT infrastructure as input from the environment and process them to satisfy the information needs of different entities associated with the business enterprise.

There are systems of control over the use of IT resources and the feedback system offers useful clues for increasing the benefits of information systems to business. The business information systems are sub-systems of business system and by themselves serve the function of feedback and control in business system.
