Businesses of every size organize data records into collections called databases. The purpose of a database is to keep track of things. At one extreme, small businesses use databases to keep track of customers; at the other extreme, huge corporations use databases to support complex sales, marketing, and operations activities. Suppose that a county planning department wants to build a new database system to keep track of building permit applications for both residential and commercial projects. The database should be available to the applicants over the Internet. You have been hired as a consultant to recommend the best strategy for creating such a database. In an essay, describe the work that must be accomplished for the four stages of development of this particular database system—requirements definition, data modeling, database design, and implementation. Identify
the inputs and outputs for each stage of development.
In Hilary Putnam's Brain-in-a-tank (BIV) precedent, a world exists in which cerebrums, a neuroscientist, a supercomputer running recreations of minds contained in a tank, and the tank itself are the main articles. These things have either dependably existed or showed up totally arbitrarily with every thing in a similar state (i.e. PCs running recreations, minds are in tanks, and so on.) Understanding this, envision the accompanying situation: You are the abhorrent researcher who screens BIV's and the encounters they get from the PCs. You guarantee that all the BIV's associated trust they are carrying on with an utilitarian life in Springfield, Illinois. One of your BIV's is code-named "The Chancellor." After some time passes, the Chancellor for all intents and purposes expresses the expression "I realize I am only a cerebrum in-a-tank," which he accepts to be valid, and afterward proceeds with his modified capacities. The BIV situation Putnam presents is one such contention setting the suspicious speculation. Much like the Descartes' Evil Genius, the incredulous speculation calls into uncertainty one's information of the outside world. While the Evil Genius depends on an incomparable deluding divinity, Putnam's BIV considers the impacts of a crazy lab rat utilizing PCs to instigate deceptive observations and encounters. Conventional doubters battle we can't observe the BIV speculation as false; if we somehow managed to allow the BIV premises as evident, at that point our encounters would seem just they directly do (Stanford 2009). Thusly, doubters keep up that we come up short on the capacity to know anything about the world outside to us. Putnam applies his semantic externalism and therefore considers the situation with the Chancellor incomprehensible. Semantic externalism is a type of externalism where "implications and truth states of one's sentences, and the substance of one's deliberate mental states, rely on the character of one's outer, causal condition" (Stanford 2009). All the more correctly, he centers his worry to the principal individual sentence, "I am a mind in-a-tank" to show that a case in which the Chancellor verbally articulated said express is essentially false. Therefore, Putnam derives that we mustn't be BIVs. I will contend that Putnam abuses the meaning of "tank" in his mind in-a-tank try, along these lines diminishing his probability of negating the doubtful theory. In this article, I will characterize semantic externalism, trailed by Putnam's utilization of it against three diverse BIV situations. If we somehow happened to acknowledge semantic externalism, at that point we would essentially recognize that how we characterize a term isn't the sole factor in choosing what the word intends to us. A typical precedent would be the examination of a recognizable substance (e.g. water) and how its importance would stay consistent even before experiencing it. All the more accurately, the individuals who cling to semantic externalism would see "water" as a term credited to a substance with a compound sythesis of H2O before researchers had observed the particles containing it; in any case, the creation of this substance we had marked "water" did, to some degree, add to our significance (DeRose 102). For Putnam, communication with things on the planet speaks to the outside factor. For instance, consider two individuals who have the equivalent mental states and after that begin communicating with substances which are cosmetically comparable while still made out of various atoms. Maybe one individual collaborates solely with Ag (silver), and alternate cooperates just with ABC, yet both take in "silver" to allude to every one of their particular substances. Accordingly, every individual would have the equivalent mental states (wants, convictions, volitions, and so forth.), yet with contrasting in what they reference; "silver" would mean Ag for one, and ABC for the other. With the goal for Putnam to interface semantic externalism to his BIV test, he starts by noticing that it is important to recognize that any enunciation of the sentence "I am a mind in-a-tank" has all the earmarks of being self-disproving. All the more exactly, if we somehow happened to keep up this sentence to be valid, the sentence would at present infer a false end since we couldn't state "I am a mind in-a-tank" and realize that I am in such a state. Take for instance the announcement "[t]here is no positive articulation." If you see this announcement as evident, it would need to be false in light of the fact that it is an unmistakable proclamation. On the off chance that you placed the announcement to be false, the appropriate response is still false. To show how this identifies with Putnam's BIV's, first accept that we really exist in the substantial world (T) similarly as usually held, rather than in tanks (case T, where T is the Tangible world.) We have the accompanying: (T1) If I live in a Tangible world, I am not a "Mind in-a-tank." (T2) In occasion T, I live in a substantial world. (TC) I am not a "Mind in-a-tank" (True)(T1, T2) I am not a BIV. (TC) Next, consider we are currently the cerebrums in the tanks an alternate case (occurrence BIV). In this case BIV, a mind boggling registering framework consistently encourages us amazing encounters. In this way, we currently have the confused processing framework sending us signals for us to build our encounters. Presently we have an alternate issue in occasion BIV: (BIV1)If I am a genuine BIV, a PC is sending me exceptional encounters. (BIV2) I am a genuine BIV. (BIV3)A PC is sending me marvelous encounters. (BIV1, BIV2) (BIV4)If I express "I am a BIV", I am a mind in-a-tank. (False, BIV3) (BIVC) "I am not a cerebrum in-a-tank" (True) (BIV1, BIV2, BIV3, BIV4) Subsequently, "I am not a mind in-a-tank" (BIVC) To illuminate, semantic externalism infers that the subject will never cooperate with the Tangible tanks on the planet. In this way, when the Chancellor emphasizes "tank," he doesn't mean substantial tanks, however rather the starting point of these electric motivations. All the more absolutely, when he says "tank" he implies counterfeit tanks since he really communicated with a PC program. On the off chance that the Chancellor was alluding to a cerebrum in the occurrence BIV, that mind would allude the electrical motivations sent from the PC as fake tanks. Accordingly, we land at the accompanying situation: (BIV1) "I am a mind in-a-tank" (False); (BIV1) infers (BIV2) "I am not a mind in-a-tank" (True) (BIV1, BIV2) infers we are not minds in tanks. Subsequently, the idea that "I am a mind in-a-tank" gives off an impression of being a self-disproving as per Putnam. After Putnam trusts he has built up this self-invalidation, he should frame a conventional (i.e. all around relevant) contention (U). Henceforth, the accompanying occurrence: Emphasis of (U1) "I am a mind in-a-tank" (false, fundamentally); (U2) "I am not a mind in-a-tank" (from U1)(true, fundamentally) (UC)If I am not a mind in-a-tank, at that point we are not cerebrums in tanks. We are not minds in tanks. (UC) The articulating of "I am a mind in-a-tank" must be false since the occurrence BIV reasons that we are not cerebrums in tanks. Therefore, we mustn't be minds in tanks as per this rationale. While at first glance this may appear to be sound, I plan to demonstrate how Putnam may have come up short. At first look, the rationale behind the Tangible world occurrence, the BIV example, and the Universal occasion may appear to be indistinguishable seeing that they each find we are not minds in tanks; in any case, every stipulation joins an alternate importance of "tank." The "tank" utilized in the Universal case speaks to a dark term between the initial two referenced cases (i.e. Substantial world and BIV case); the Tangible "tank" speaks to tanks from the unmistakable world similarly as we would see it today; and the BIV "tank" represents the virtual tank that the overly wonderful PC has made for us with its electric signs. Putnam's blunder happens when he doesn't universalize the tank definition by utilizing the last feeling of the fake tank all through occurrence BIV. While somewhat befuddling, it appears Putnam thinks about the occasion (BIV1) since the main time it is genuine is in the last feeling of "tank." Putnam additionally needs to attach this definition to the Tangible world. All things considered, we as a whole live in the unmistakable world and would need to trust we are not cerebrums in tanks while in the substantial world. Tragically, utilizing somewhat extraordinary definitions amid an endeavor to demonstrate this end hampers the contention. As such, his contention is either that '(BIV1) suggests (BIV2) infers (TC)' or that '(BIV1) infers (T2) infers (TC); in any case, these contentions neglect to remain constant. It is superfluous to consider the two potential outcomes inside and out autonomously, since they can both be renounced on similar criteria. In the case of going from (BIV2) to (TC), or from (BIV1) to (T2), Putnam mentions an objective fact about BIV-tanks, and afterward utilizes that to make a case about Tangible-tanks. The genuine explanation, (BIV2) "I am a not a mind in a virtual-tank" neglects to suggest "Not being cerebrums in unmistakable tanks." Likewise, (T2) "I am not a mind in a substantial tank" being valid, neglects to pursue from (BIV1) "I am a mind in a counterfeit tank" being false. The absence of a consistent meaning of "tank" presents one critical hindrance for Putnam; be that as it may, in the event that you keep up a specific level of what establishes "tank," the contention still stays invalid and keeps running into different issues which I won't address here. I have endeavored to contend that one can't get to (TC) from (BIV1); notwithstanding, any individual who buys in to Putnam's contention against cerebrums in-tanks may contend the inverse. It is essential to perceive the conditions encompassing the contention. All the more absolutely, Putnam surmises we live in the regular world. The doubter's primary contention is that we come up short on the information to recognize regardless of whether we exist as minds in tanks. We would just have the capacity to separate between the examples and the tank utilization on the off chance that we new conclusively which cases were being referenced. >GET ANSWER
