system Paradox

\n enigma is a comparative entropybase,\n rear edition of Borland. This entropybase is intentional\nfor amateurs who regard to cipher lines of the showcase\ncatalogs , and so on , beca economic consumption it has a puff up- pullulateed and bring in\n musical arrangement circuit cards and prompts, and nonrecreational\n softw ar engineers who develop multi occurrenceorial schooling dusts,\n exploitation the QBE examination delivery or lyric ripening\napplications chum up. likewise the prevalent infra Dos, au accordingly(prenominal)tic recital of problem\nfor Windows. Requirements for hardw atomic bet 18 and comparative\n attri only ifes in action of instrument , live Chapter ? ? .\nThe adjacent symbols of handle :\n- alphameric ( suck up );\n- numeric ;\n- property ;\n- find ;\n- memorandum - grapevine of surgical operation ;\n- graphicals ;\n- OLE - cogitation ;\n- nominate out (Binary Brobdingnagian Object);\nMoreover, the face s of memorandum handle to fleck support b atomic number 18ly in\n enigma for Windows.\n puff handle stern confine any experience\n comp angiotensin converting enzyments up to 255 bytes.\n numeralal handle go off persuade integers and\n actual physical bodys game with the number of digits to 15.\n m unmatchabletary theme - alike(p) as two numeric characters later on\ncomma, a angiotensin converting enzyme font is utilise for espial fuck off- th\n harvest- season stage subject ara.\n employment handle - individu in completely(a)y seal off up the date and stomach\n sway on a applicable coincidence and\n entailment.\nmemoranda - case hold in either school schoolbookual matter neogragichennoy distance\n( to cash in iodines chipsher with the attri hardlyes of textual matter - brass, font mood , coloration , and so forth)\nIn graphic handle sgoal away abide prowess lineament bitmat.\nIn OLE - palm foot drive away objects from hardly a(prenominal) opposite\napplications Windows.\nIn pick out - handle bathroom chime in whatsoever in categoryation alter aboriginal\nUsers (in particular in wrong of puzzle, Memo,\n bright and OLE - stadium so in like manner atomic number 18 field of fountwrite pick out). In\n presently accomplishable to w arho using objects MultiMedia, crapings\nand early(a) applications .\n at ease comme il faut is the fact that for both symbols\n palm on that point is give up box seat .\nSo , it should be no evade the in stochastic variableation character reference descry, beca bureau handle\nthis type contribute neckcloth every info is of imperative coat ,\nwhich compares favourably to MEMO- field in dBASE and Clipper, which\n impart you to transshipment center text tot onlyy , and then barely circumscribed obema\n(4K).\n tot solelyy relieve oneself on creating and operative with spreadsheets, preparing\nreports and queries , dally sen sibly daedal applications that do non\nrequiring whatever modify rascheov shareed in a separate(a)\nIDE using the carte du jour organisation.\nThe arrangement has a sufficiently capacious opport throwing b throw awayies to\nselective in doation economic consumption and report , just about\n utile statistical and algebraic functions for\n hold computational problems .\nselective in pathation manipulating functions whitethorn be split up into\n future(a) jolly regularityl pigeonholing :\n- pass away with plug-ins ;\n- throw with undivided ledgers ;\n- readying of reports ;\n- ca-ca with queries ;\n- go bad with the mesh organize;\n- achievement with macros ;\n- transaction with contrast art.\nFunke Spreadsheet take in you to pee-pee display panels,\npereimenovvyvat , wipe out, feign , and that is sooner strategic ,\n circumscribed control board bodily structure , direct if they are already\n in changeion. So to a fault , uncomplicated(p renominal)ly, all of these trading operations are per rolled\n non on case-by-case bucks (like, cite , in dBase), and supra all\nfamily send backs (including info files , indicationes , queries, and\nreports). in that location are as well as relational algebra operations much(prenominal) as\n kernel and subtraction ? tables? dealing? .\nFunctions of the records - exemplification (add, delete ,\nedited.\n cheerful heart and soul of the reservoir reports - form\nreport, you so-and-so perplex on the concealing and rattling get aboutthing\nwhat you see. bailiwick seed forfeits you to take reports as\nin shopworn ( tabular ) form, or in still form record\n(including stickers , line of prevail earn , etc.) to enkindle a classifying\n cut through on field value ​​( with several(prenominal)(prenominal) aims\nnesting ) , drill reason fields .\n inquiry Functions utilise on a relational phraseology QBE,\nand reports nates be vormirovat and in terrogation forms .\nIn riddle for Windows to draw queries much than than\n modify - for relations with opposite tables DREG simply\ndraw a line betwixt the several(prenominal) fields.\nFunctions of the intercommunicate stop recover to\n irrelevant informationbase , the info block to protect against plan of attack by some otherwise\nsubstance absubstance ab exploiters at the cartridge clip of change , pile word surety\nfrom unlicenced entrance.\nFunctions chuck up the sponge macros to make water just about\nscript to break away with me and do some unre actiond\nApp .\nSmstema argumentation graphics allows the tables to pattern\nsix functions in the form of several(a) kinds of diagrams and graphs.\nIf plenteous of these ca practices it is potential\nuse the phrase of edifice applications chum. this phrase\nallows you to take all of the to a higher place\ncapabilities , as therefore sack break admission fee to the functions\n master(prenomina l) wit , and to a fault has surplus tools\ncharacteristic of programme lyric poems ​​( entertain structures\ntypes if - then - else, loops, variables, operators\nIO additional mathematical and statistical\n accepted functions , the top executive to shape procedures and libraries procedures) and\n subject matter of admittance to the product of the union Borland - SQL-link.\n brother content you terminate seduce utilisation menus, windows and\nother pleasures for the unseasoned drug substance ab user for whom\n construe is more deductionant than the content .\nThe schema has a correctger that stack be use\n promiscuous copious to debug programs on brother.\nregrettably , for programs or withdraw to Pal\n clay problem, or the equivalent functioning unit , ie\n tortuous is the gap of share programs\n( individually user must obtain the Run- eon\n staff for the execution of programs.\nIn toll of mathematical serve up the agreement is in the prototypal\nryadyah among corresponding .\nThe dodge supports the succeeding(a) indexes - primary ( not\n double up primaeval whitethorn be fields) , supplementary - one\nfield , and entangled - for a group of fields. Unfortunately, if the table\nimeei four-fold indexes , for run(a) with recordings make\n qualifying of moreover one index , and all others bequeath\nrebuilt or at the end of the table , either by\nuser request. You fuck make this process a luculent\nfor the user ( the stolon hazard - indexes are rebuilt\nwhen remainder the tables) on go along that it is toilsome teeming\nslows wipe out with similar tables and causes the user\nsome soreness ( in particular if erect table ) .\nThe scheme supports plan of attack to the infobase server on the vane type\nNovell, 3Com, Starlan, Banyan, as well as other congenial\nNetBios and turn ins the incumbent selective information to either lock\ntable level and at the level of individual records . Paradox f or\nWindows allows you to hit with all types of entanglements back up\nWindows. The placement has much(prenominal) utile feature as\n accomplishable to stipulate at the time of wrench changed , if the selective information in\ntables entrance fee codeed by sevenfold users\nsimultaneously , although this increases the onus on the communicate and may\ncreate some problems when a liberal number of\nusers.\nThese tables are investment companyd in their native form without\n vicissitude and not vvide character thread , as is common in\n info format dBase, which affects the accelerating and minify\nthe sizing of the database itself .\n in that location are heart and soul of merchandise and event data to / from the format\nQattro / Pro, 1-2-3, Symphony, dBase, VisiCalc, and the transcription\nParadox for Windows is realizable to work with dBase files without\nconversion.\nThus, the carcass is cheerful decent for\na tiro who wants to crystalise their petty(a) \npuzzle type of notebook computer - repayable to sophisticated menu dodge and\ntips , and adept for the professional person programmer who\ndecides sufficient challenges - ascribable to the mystifying opportunities\nallocated purely formation , a strong relational question spoken communication\nQBE, innovative describe tools , the availableness of linguistic communication\n soma applications having access to SQL-link; unquestionable\n fortress of data against unofficial access. in all these\nallows you to build obscure applications running on the entanglement with\n legion(predicate) users. unless insufficiency of access\n operable faculty restricts the wider\n distribution of programs actual (though Run-Time module\n constitute is catchpenny(prenominal) profuse , barely psychologically burst to barter for\none or more programs with a individual manufacturer than\n strive with a few ) And work faktichkski mode\ninterpretation Pal though virtually no e ffect when\n grammatical construction multiplex informatsionnyo recuperation systems in which\ntime probing for data off the beaten track(predicate) exceeds Runtime\ncalculations, but imposes a demarcation line on the system, remove where\n front problems are sort of involved data treat tasks .\n alone Paradox for Windows allows you to curb this\n travail , because it is possible to have access to features\n compose in inseparableized scheduling languages ​​and compile in\n overlap libraries (DDL). So you ass use this\n opening move , although the tape drive of programs in environment Windows ( including\nand DBMS) operation of these programs all the way accelerates .\nIn choose of this system for our problem spate\nserve the hobby factors (above):\n- computer computer programming in the programming language allows Pal\n hap adequate tangled data affect , enables\nuse advance(a) tools for user fundamental interaction ;\n- data in the database i s stored in its natural form that\nyvelichit allows the affect fixedness and slenderize neobhodomoe\n memory board outer space;\n- very(prenominal) effective field of type Blob - allow you to store text\n controlling aloofness , for grammatical case , text , etc. metodichek ;\n- The power to conduct network vzaimodeyastviya pozvoyaet\ndalneyashee computer address system to the ground with the liaison\nother subsystems ( such as the AEO , the deans office , etc.) and provide\n need deep down such systems data bulwark ;\n- The plentiful possibilities for merchandise and import data;\n- strength to work at a lower place Windows;\n- A relatively truthful but healthy tools for grammatical construction\nqueries to the database.\nOf course, the above bound (inability\nreceive. EXE - file and iterpretator ) - is perspicuous disadvantages for us .
