Types Information System Assignment | Components of Information System

Types Information System Assignment Transaction processing system (TPS): This type of information system is mainly considered at operational level of organisation so it located at Types Information System Assignment | Components of Information Systembottom of pyramid. Such information system directly operated by front line staff, shop floor worker. The data taken through this information system is support the management operation also. It includes simple data processing. It produces basic information for next information system (Stair and Reynolds, 2013). Organisation most commonly use transaction processing system like- payroll system, reservation system, stock control system and fund transfer. The main role is to generate information from operational level and improve efficiency for next level.

The input of TPS is events and transaction.Processing include sorting, merging, calculation, updating and validating etc over Input.It generates List, Details and Action Reports and summarised report also.

Management Information System (MIS): This type of information is mainly used by middle level management. It allows managers of organisation to evaluate current performance of organisation by comparing output against expected output. The information system also helps middle manger to ensure smooth running at medium term. It process data on the basis of TPS output. The examples of this information system are inventory control management, sales management and budgeting management. It deals with past and present analyses not future.

The input of MIS is files, records and structured data from TPS.Processing include sorting, merging and summarizing.It makes summary of report and action report.

 Decision Support Systems (DSS):

It is also known as knowledge based information system and mainly use by senior managers. Barclay’s organisation can use this system to analyse existing structured information and find effects of their decision in future. It makes the system interactive and solve ill structured problem. Examples of DSS are Logistics system, financial planning system and group decision support system. It mainly concern with predicting the future (et.al.2015).

The input of DSS is internal files and records and external information.Processing include analyses, modelling and simulation over input data.It makes summarised report, performance graph and forecast data.

Executive Information System (EIS): It can used by executives and senior managers of Barclays organisation. It is also known as strategic level information system. It is used to analyse the environment in which organisation operates. Apart from this, it defines long term trends and appropriate plan.  It is directly operated by executives without need of intermediaries. The information system is highly individualised and custom made on particular client group (Stair and Reynolds, 2013). The information system is used for predicting future, ease of use and provides flexibility in decision making. .

The input of ESS is External files and internal data, records from DSS and MIS.Processing include simulation and analysing.It makes summarised report, graph/plots and forecasts data.
Describe current trends in information systems to solve problems in business organizations

Current trends of information system those are able to solve problems in business of Barclay’s organisation. These are listed below:

Types Information System Assignment | Components of Information System

Big data

It has been identified that Barclay’s organisation wants to make informed business decisions and becoming more intelligent. Amazon, Google are some example that use big data by lending decision from algorithms. It would generate credit rating, budget and logistic planning in order to bring advancement in next year. So that big data is related to data analysis so that organisation takes some competitive advantage by finding market demand. Big data are large and complex data set. The main challenge is to analyse, capture, share, storage, transfer and updating information. In present scenario, it is used for predictive analyses by advanced method to extract valuable data and particular size of data from big data. This leads to build confidence while decision making on critical projects in organisation (Zikmund.et.al.2013). It also improves operational efficiency, reduce cost of operation and risk also.

Cloud computing

The organisations are suffered from risk on data base or big data. The sensitive information, research and analytical information are stored in their data base. But the storage can be damage due to some internal error or data can be damage due to attack on database. Apart from this, organisations are considering most important technology that allows employee collaboration of different stores. Information access is available at any branch of organisation. Apart from this, information backup is also maintained at cloud which is available to provide faster recovery of data base (Fichman.et.al.2011). Information systems are processing, analysing, merging, sorting, summarising data and make reports by cloud computing where organisation’s data is stored. It covers risk on information system.

Cyber security

Barclay’s organisation is sharing information and sensitive data is sent from external network. Employees are accessing database from out of work environment also. Apart from this, information is send over network to business executives and clients. Data base also store compete details of customers. Therefore, a new trend of cyber security is emerging with information system. It includes data encryption technology by various encryption algorithms that provide secure communication over unreliable network also (Da Xu, 2011). It includes data signature and key exchange methods so that third party is not able if hack information. If attacker takes data packets but he/she would be unable to translate and cannot get actual information because data packet is encrypted by cyber security technology.

Business intelligence (BI)

Business intelligence techniques and tools are used to transform raw data into meaningful data. It is capable to handle large amount of unstructured data. Barclay’s organization can use BI tools in order to indentify, develop new strategies for business. The main objective of BI is to interpret large volume of data and identify new opportunity for business. Therefore, it is effective new trend to gain competitive advantage and provide long term stability in business. Common functions of BI are data mining, reporting, process mining, complex event processing and online data analyzing.
