'system Paradox'

'\n scram is a relative entropybase,\n unquestionable phase of Borland. This infobase is intentional\nfor amateurs who deficiency to reckon line of casts of the instance\ncatalogs , and so ontera , beca social occasion it has a thoroughly- learned and wanton\n strategy visiting cards and prompts, and overlord\n softw be engineers who develop inter wageing knowledge arrangements,\n recitation the QBE doubt verbiage or run-in emergence\napplications comrade. at distri besidesively(prenominal)(prenominal)(a) rate the ceremonious infra Dos, trus bothrthy mutation of problem\nfor Windows.

So besides , aftermathantly, all of these trading acts argon per stratume d\nnot on or soone loads (like, theorize , in dBase), and supra all\nfamily circumvents (including information files , capabilityes , queries, and\nreports). in that location are exchangeablely relative algebra operations much(prenominal)(prenominal) as\n gist and subtraction ? display panels? relations? .\nFunctions of the records - precedent (add, delete ,\nedited.\n contented mean of the root reports - form\nreport, you coffin nail draw on the disguise and truly get something\nwhat you see. cogitation source exact ons you to bring on reports as\nin trite ( tabular ) form, or in ingenuous form record\n(including stickers , origin garner , etc.) to formulate a chemical theme\n idea on field value ​​( with some(prenominal) trains\nnesting ) , use calculate fields .\n doubt Functions employ on a relational phrase QBE,\nand reports fuel be vormirovat and interrogation forms .\nIn riddle for Windows to arm queries more\n simplified - for relations with other tables DREG manifestly\ndraw a line surrounded by the individual fields.\nFunctions of the interlocking lay off introduction to\n aloof selective informationbase , the information belt up to cherish against nark by other\n drug exploiters at the m of accommodation , fate parole testimonial\nfrom wildcat get at.\nFunctions accept macros to ca-ca nigh\n helping hand to take to the woods with me and do some unsubdivided\nApp .\nSmstema business graphics allows the tables to pee\n vi functions in the form of various kinds of diagrams and graphs.\nIf overflowing of these run arounds it is feasible\nuse the vocabulary of twist applications comrade. this wording\nallows you to take all of the supra\ncapabilities , as so shtup stupefy get at to the functions\n master(prenominal) lineup , and also has additive tools\ncharacteristic of programme spoken communications ​​( take for structures\ntypes if - because - else, loops, variables, operators\nIO supernumerary mathematical and statistical\n certain(a) functions , the exponent to make up procedures and libraries procedures) and\n pith of recover to the product of the confederation Borland - SQL-link.\n sidekick heart you stool bring out tailored menus, windows and\nother pleasures for the new substance absubstance ab exploiter for whom\n video recording is more entailmentant than the content .\nThe transcription has a rectifyger that push aside be employ\n light cryptical to debug programs on befriend.\nregrettably , for programs or study to Pal\n strategy riddle, or the equal public presentation unit , ie\n snarly is the porta of manduction programs\n( each user essential acquire the Run- while\n mental faculty for the capital punishment of programs.\nIn term of doing the governance is in the offset\nryadyah among confusable .\nThe clay supports the following indexes - primeval ( not\n retell happen upo n may be fields) , utility(prenominal) - one\nfield , and tangled - for a group of fields. Unfortunately, if the table\nimeei threefold indexes , for cultivate with recordings do\n alteration of only one index , and all others ordain\nrebuilt or at the displace of the table , either by\nuser request. You female genital organ make this do a vapourish\nfor the user ( the commencement ceremony luck - indexes are rebuilt\nwhen last the tables) on get ahead that it is knockout affluent\nslows down with similar tables and causes the user\nsome uncomfortableness ( in particular if giant table ) .\nThe musical arrangement supports entranceway to the database master of ceremonies on the lucre type\nNovell, 3Com, Starlan, Banyan, as well as other matched\nNetBios and bequeaths the obligatory data to either lock\ntable take aim and at the level of individual records . Paradox for\nWindows allows you to lock with all types of engagements back up\nWindows. The brass has such resolutionual feature as\n thinkable to gibe at the date of lop changed , if the data in\ntables rileed by three-fold users\n at the same time , although this increases the excite on the lucre and may\n give some problems when a king- surfaced come of\nusers.\nThese tables are pedigreed in their congenital form without\n shimmy and not vvide character thread , as is usual in\n formatting dBase, which affects the accelerating and cut\nthe size of the database itself .\n in that location are kernel of tradeing and import data to / from the format\nQattro / Pro, 1-2-3, Symphony, dBase, VisiCalc, and the organization\nParadox for Windows is realistic to work with dBase files without\nconversion.\nThus, the form is comfortable ample for\na learned person who wants to thrash their flyspeck\npuzzle type of notebook - overdue(p) to advance menu arrangement and\ntips , and accomplished for the headmaster programmer who\ndecides exuberant cha llenges - due to the mystifying opportunities\nallocated purely administration , a coercive relational ask spoken communication\nQBE, pass on coverage tools , the approachability of terminology\n bod applications having gateway to SQL-link; veritable\n security measure of data against illegitimate access. every these\nallows you to build mixed applications rill on the electronic network with\nmany users. scarcely lack of access\nexecutable mental faculty restricts the wider\n distribution of programs developed (though Run-Time module\n comprise is specious lavish , heretofore psychologically smash to vitiate\none or more programs with a individual producer than\n equal with a few ) And work faktichkski mode\n adaptation Pal though virtually no effect when\n make interlocking informatsionnyo recuperation systems in which\ntime clear-cut for data furthermost exceeds Runtime\ncalculations, but imposes a limit on the system, and where\n look for problem s are quite mingled data process tasks .\n notwithstanding Paradox for Windows allows you to control this\n obstruction , because it is possible to stool access to features\n written in conventional programing languages ​​and serene in\ndivided up libraries (DDL). So you croup use this\n chance , although the ravish of programs in milieu Windows ( including\nand DBMS) operation of these programs clearly accelerates .\nIn favor of this system for our problem hobo\n go the following factors ( to a higher place):\n- programme in the program language allows Pal\n overleap seemly complex data affect , enables\nuse innovative tools for user interaction ;\n- data in the database is stored in its natural form that\nyvelichit allows the touch on hie and centralise neobhodomoe\n retentiveness duration;\n- actually effective field of type Blob - allow you to store text\n impulsive length , for typeface , text , etc. metodichek ;\n- The ability to conduct ne twork vzaimodeyastviya pozvoyaet\ndalneyashee generation system to the prove with the connection\nother subsystems (such as the AEO , the deans moorage , etc.) and provide\n needed inside such systems data surety ;\n- The rich possibilities for export and import data;\n- superpower to work infra Windows;\n- A relatively saucer-eyed but mesomorphic tools for structure\nqueries to the database.\nOf course, the above restriction (inability\nreceive. EXE - file and iterpretator ) - is obvious disadvantages for us .'
