Transaction Processing Systems

Transaction Processing Systems ( or TPS for short ) are critical systems in any concern, these systems are responsible for functioning the operational degree of an administration. Examples of some TPS systems would include:

  • Recording payments received for goods and services.
  • Puting orders for merchandises or services.
  • Withdrawing money at a hard currency machine.

TPS ‘s are in contact with the clients all of the clip and if one were to neglect so it would be instantly evident, if Tesco ‘s boulder clay systems were to neglect so the client would be cognizant of this instantly. This outlines the great importance of these systems, while they may look to be insistent, they must finally be dependable. This means that although 100 % dependability can non be guaranteed, the TPS must hence be able to observe and right mistakes. ( Wikipedia, 2009. Transaction Processing System. )

However, non all minutess are processed instantly ; there are two different types of dealing systems. Real clip treating systems process the minutess instantly, this method keeps information up-to-date and information within the studies will be systematically accurate. Batch treating systems store the information in batches and are processed at slower rates, this method of processing agencies that studies do non ever hold up-to-date information. Businesses necessitating up-to-date studies will choose for a existent clip processing system. ( Bocji, P 2003 p238 )

Tesco will profit from these Transaction Processing Systems in assorted ways. These systems will keep and roll up information about client purchases, particularly those who have a client trueness card ; it will help in being able to aim other merchandises at these clients to assist increase gross revenues. Automatic links with providers will be improved as stock can be re-ordered every bit shortly as it has been sold, greatly cut downing the physical attempt of stock ordination and understating the mistakes involved with manual ordination. Greater effectivity of client service as monetary values can be modified with easiness, a greater pick of merchandises can be attained and lower monetary values to the client.

Tesco uses TPS ‘s in their EPOS systems ( Electronic Point of Sale ) these systems scan barcodes and communicate with the in-house system. This in-house system will enter all the informations of minutess and stock which needs to be re-ordered, likely in a batch system which can so be transferred to the mainframe at the terminal of the twenty-four hours. This information will so be accessible to higher direction for bring forthing studies and will supply the distribution Centre with orders for the undermentioned twenty-four hours. This information will besides supply telling information for 3rd party providers.

Decision Support Systems

Decision Support Systems ( or DSS ) are the direction information systems aimed at back uping the managerial degree. These systems provide information, normally in the signifier of ad hoc studies to help with determination devising.

The theoretical accounts bases that power DSS ‘s vary from standard analysis to complex mathematical relationships between variables in the information. DSS ‘s are usually accessed from a computing machine, giving the director the ability to publish the DSS package bids and petition specific informations. The end product from the DSS package is normally in an easy to understand text and ocular format ( such as graphs and charts ) .

DSS ‘s are a combination of particular theoretical accounts that aid with information analysis, prediction and planning. Company public presentation informations is besides portion of this integrating. DSS are normally non a corporate system and be given to be more departmentally targeted, normally moving as a selling aid. Normally DSS ‘s are used as a specializer system such as an adept systems or informations repositing, nevertheless they are aimed to be really easy to utilize and should “integrate across all degrees in acknowledgment of the convergence between operational, tactical and strategic decisions” . ( Bocij, P 2003 p253 )

Adept systems replicate the cognition and determination devising accomplishments that a professional in a certain field would hold. These systems are critical tools in determination support ; a good illustration would be doing a recognition determination on whether or non to give person a personal loan.

Data repositing is a type of concern intelligence package that analyses dealing information to heighten a company ‘s fight. The information warehouse itself is a monolithic database which contains a company ‘s sale information. Data excavation is used in association with informations warehousing and is an machine-controlled manner to happen forms in informations. Data bunch can besides be utilised in order to happen relationships between groups or parts of the information. ( Wikipedia, 2009. Data Mining )

DSS ‘s can be used to make jobs, directors can analyze the informations when certain variables are changed, or looking at different scenarios. Some types of the happenings include:

  • Data Mining, as already discussed.
  • Goal Seeking Analysis, altering variables one at a clip until a coveted end is achieved, making this enables the director to see what ends need to be set in specific countries of the concern to achieve coveted consequence.
  • What If Analysis, like end seeking analysis but involves altering a figure of variables at one time or altering a relationship within the variables, while maintaining an oculus on the alterations in the other variables.
  • Optimization analysis, to happen an optimal value for the variables given certain conditionals.

Taking Tesco as an illustration you can presume that via Transaction Processing Systems, assorted informations is collected in the shops. This information is stored in the company chief frame system and can be accessed by departmental directors for them to bring forth studies via adept systems or informations mining/warehousing. This enables the directors to acquire information such as how many clients enjoy eating poulet in comparing to those who prefer beef ; this can so be coupled with information such as what other merchandises the consumer purchases along with these points.

The directors at Tesco could so happen information about point affinity, a procedure that would foreground the likeliness of a figure of points being purchased together. This information is of great importance when sing what particular offers to set on, it could help in happening other suited merchandises to set near to these particular offers. ( Information Management, 2006 )

The success of point affinity is apparent by the narrative of the beer and nappies, it was found that work forces were purchasing nappies along with beer on Friday darks. This is an unusual happening that you would n’t usually foretell ; nevertheless, it was thanks to informations excavation and point affinity that this was uncovered. ( The Register, 2006 )
