Paper Abstract: This paper examines the IRS's information systems and discusses the CADE database that is currently on hold, recommending a solution for the problem. Abstract included. Paper Introduction: Computer and Information Processing AnalysisAbstractThe Internal Revenue Service\'s computer systems are extremely numerous andthere are multiple databases from multiple vendors that are in use at anygiven time The CADE database was implemented in to serve as the maintaxpayer information database but development on CADE has beeninterrupted This paper examines the organization\'s information systemslandscape and CADE in particular offering recommendations for how thesystems should be revamped The Internal Revenue Service the IRS has an information systems problemthat virtually all government and other mega-sized Text of the Paper: The entire text of the paper is shown below. However, the text is somewhat scrambled. We want to give you as much information as we possibly can about our papers and essays, but we cannot give them away for free. In the text below you will find that while disordered, many of the phrases are essentially intact. From this text you will be able to get a solid sense of the writing style, the concepts addressed, and the sources used in the research paper. (2 3). If CADE was halted due to complexity, this suggests that it was notdesigned to handle the level of workload that the IRS has, which is alwaysincreasing. I would recommend that a higher-level modular system be designed froma top-down perspective and that CADE be used as just one of the modules inthe system. This paper examines the organization's information systemslandscape and CADE in particular, offering recommendations for how thesystems should be revamped.The Internal Revenue Service, the IRS, has an information systems problemthat virtually all government and other mega-sized organizations have-toomany systems to manage successfully and too little effective functionality. Retrieved on February 14, 2 1 from: http://www.irs.gov/newsroom/article/ ,,id=125546, .html This will provide the advantage of one unified system withoutrisking unauthorized access to information that should be restricted to aparticular department.

On the whole, bottom-up design means that whenever a newcomponent or a change is needed, massive change must ensue, while top-downdesign generally means that the new component can be added easily andchange can be limited to just one segment of the system. (2 9). GAO: IRS Halts Development of Customer Account Data Engine. (2 ). Information Technology. 43). Modular design would ensure that if any modules needed to beadded or removed in the future, this could be done in a relatively shorttime frame without compromising the operation of the remainder of themodules or the system overall. VI. One of the key databases in the IRS complex of systems was theCustomer Account Data Engine, or CADE, which is based on DB2 technology("New Taxpayer Account, Processing System Debuts," 2 4; Gross, 2 3).CADE was supposed to be phased in over several years starting in 2 4 andwas expected to contain more than 2 million taxpayer accounts atcompletion, promising faster refunds and daily account transaction postings("New Taxpayer Account, Processing System Debuts," 2 4). When it comes to databases, "theentire IRS inventory of systems is built on a fundamentally deficientfoundation," and its size is commensurate with the largest systems on theplanet (Rossotti, 2 , p. IRS.gov. Modernizing America's Tax Agency. IRS database upgrade delayed again. However, in June2 9, progress on CADE was halted because of "unexpected complexities"(Jackson, 2 9). The CADE database was implemented in 2 4 to serve as the maintaxpayer information database, but development on CADE has beeninterrupted.

First, thetop-down, modular design would create a high-level framework that newcomponents could fit into, ensuring that they would be consistent with eachother. Bottom-up designinvolves designing the system from the detail level first rather thanlooking at the overall system requirement and designing the details to fitinto that. Government Computer News, (Jun 5). Retrieved on February 14, 2 1 from: http://gcn.com/articles/2 9/ 6/ 5/irs-electronic- filings.aspxGross, G. Moreover, on an ongoing basis, I wouldrecommend that the IRS seek to simplify its system and bring as manyindividual applications as possible under the umbrella of the new top-downmodular system so that access to data would not be compromised, redundancywould be minimized, and interoperability of systems would be promoted. Finally, there would be far less opportunity forerror in this tightly designed system than in the current hodge-podge ofoddly assorted systems that currently exists. Inaddition, security should be incorporated into the new system to ensurethat only authorized departments and individuals can access specificmodules. Most likely, the system was designed bottom up rather than topdown, since bottom-up design can easily be overwhelmed by changes orincreased complexity, while top-down design takes into consideration thebig picture and rarely results in rapid obsolescence. 41). The IRS's current problem of systems that do not communicateinformation to each other readily would be overcome using this approach.Second, as modules of a single program, the different programs anddatabases would be potentially accessible to each other, so that noredundancy is needed. ReferencesRossotti, C.O. The IRS technology inventory includes 147 mainframes from 19 differentvendors, 1,62 mid-range computers from 55 different vendors, and more than1 , individual computers, which are needed to run more than 8,7 vendor-supplied software products and 82 million lines of code maintainedby the IRS (Rossotti, 2 , p. Darby, PA: Diane Publishing Company. In the end, the IRS wouldbenefit by having better access to information and a more complete andintegrated system. IDG News, (Aug 4). Computer and Information Processing AnalysisAbstractThe Internal Revenue Service's computer systems are extremely numerous, andthere are multiple databases from multiple vendors that are in use at anygiven time. Thus, top-downdesign promotes greater system integrity and is always preferable but isnot usually used in a system like the IRS's, where no one has a grasp ofthe overall requirement and everything is done at the individual systemlevel. This solution would provide several advantages to the IRS. If this paper is not what you are looking for, you can search again: Search for: or Click here to request an essay written just for you.
