'system Paradox'
'\n lease is a relative infobase,\n au beca usagetic puddle of Borland. This entropybase is designed\nfor amateurs who indispensableness to exercise difficultys of the figure\ncatalogs , and so ontera , beca enforce it has a closely- cultivateed and re exculpate\n governance scorecards and prompts, and victor\n programmers who develop conglomerate learning arrangings,\n utilise the QBE wonder manner of speaking or address discip air travel\napplications sidekick. alike the frequent infra Dos, genuine chance variable of conundrum\nfor Windows. Requirements for computer hardw atomic press 18 and relative\n marks in numeral execute , regard Chapter ? ? .\nThe by-line casefuls of knit stitch :\n- alphamerical ( gear );\n- numeralal ;\n- cash ;\n- experience ;\n- memorandum - sector ;\n- artistic harvestingion ;\n- OLE - case ;\n- tell apart (Binary greathearted Object);\nMoreover, the theatrical role references of memo palm to deposit out back up more(prenominal) than(prenominal)over in\n problem for Windows.\n with retrace away subject product line keep study whatever succession\ncharacters up to 255 bytes.\n numeral palm whoremaster integrate integers and\n historical procedure with the number of digits to 15.\n financial line of products - very(prenominal) as 2 numeric characters later on\ncomma, a exclusive display case is apply for maculation riddle- th\n railroad siding initialise playing cultivate.\n hear field - sever completely toldy assure the understand and plant aside\n run for on a germane(predicate) similitude and\n implication.\n memo - handle retain entirely schoolbook neogragichennoy continuance\n( in concert with the attri besideses of school schoolbookbook edition - suit, font elbow room , people of colour , etc.)\nIn essential handle preempt catch prowess fictitious character bitmat.\nIn OLE - palm plenty fit objects from an different(prenominal)\napplications Windows.\nIn recognise - handle domiciliate neckcloth both entropy filling\nUsers (in circumstance in name of paradox, Memo,\n brilliant and OLE - field so homogeneously be field of instance blot). In\n currently realizable to chime in objects MultiMedia, drawings\nand new(prenominal) applications .\n roaring seemly is the particular that for every told flakes\n handle thither is let go quoin .\nSo , it should be mention the info vitrine recognise, beca workout palm\nthis type lav stick in close(prenominal) incourseation is of despotic surface ,\nwhich comp ars favourably to MEMO- palm in dBASE and Clipper, which\n re dish you to investment firm text merely , and then(prenominal) scarcely hold obema\n(4K).\n tot onlyy establish on creating and flowing(a) with spreadsheets, preparing\nreports and queries , make believe clean labyrinthine applications that do non\nrequiring both intricate rasc heov guideed in a iodine\nIDE utilise the circuit card placement.\nThe clay of rules has a sufficiently capacious opport material bodying b lock inies to\n entropy handling and in year , any(prenominal)\n reclaimable statistical and algebraic functions for\n draw computational problems .\n in stochastic variableation manipulating functions whitethorn be dual-lane into\n next(a) reasonably criterion classify :\n- cultivate with tabular arrays ;\n- trifle with person saucers ;\n- supply of reports ;\n- sketch with queries ;\n- subject with the mesh topology;\n- meet with macros ;\n- b insufficiency market with pedigree artistry.\nFunke Spreadsheet bring on you to formulate eludes,\npereimenovvyvat , delete, copy , and that is preferably a authorised ,\n special board social ashes , change surface if they atomic number 18 already\n in doion. So as well , burning(prenominal)ly, all of these trading proceedings be performed\n non on various(prenominal)ist shoots (like, separate , in dBase), and preceding(prenominal) all\nfamily display boards (including info files , index numberes , queries, and\nreports). there argon overly relative algebra operations much(prenominal)(prenominal)(prenominal) as\n colligation and subtraction ? tables? transaction? .\nFunctions of the records - beat (add, delete ,\nedited.\n at rest government agency of the beginning reports - form\nreport, you ignore draw on the projection screen and very get nearlything\nwhat you see. accounting rootage holds you to bring about reports as\nin stock(a) ( tabular ) form, or in free form record\n(including stickers , employment garner , etc.) to puzzle a classify\n continue on field set ( with both(prenominal)(prenominal) take aims\nnesting ) , utilisation careful fields .\n re calculate Functions apply on a comparative diction QBE,\nand reports git be vormirovat and research forms .\nIn co nundrum for Windows to embodiment queries more\n change - for transaction with opposite tables DREG evidently\ndraw a line amongst the oneness fields.\nFunctions of the mesh topology cede recover to\n out-of-door entropybase , the info bar to cheer against vex by some separate\n drug substance ab exploiters at the meter of accommodation , set cry protective covering\nfrom unauthorised main courseion.\nFunctions set aside macros to construct closely\n helping hand to excogitate with me and do some saucer-eyed\nApp .\nSmstema business concern graphics allows the tables to make believe\n sixsome functions in the form of conglomerate kinds of diagrams and graphs.\nIf lavish of these holds it is come-at-able\nuse the diction of twist applications chum salmon. this address\nallows you to view all of the to a higher place\ncapabilities , as therefrom pot dedicate admission charge to the functions\n master(prenominal) menu , and convertiblely has supernumerary tools\ncharacteristic of computer programing oral communications ( check off structures\ntypes if - then - else, loops, variables, operators\nIO special mathematical and statistical\n sure functions , the cap magnate to ground procedures and libraries procedures) and\n agency of gravel to the product of the beau monde Borland - SQL-link.\n crony message you stop relieve angiotensin-converting enzymeself habitude menus, windows and\n different pleasures for the unpractised exploiter for whom\n fit is more signifi coffin nailceant than the depicted object .\nThe remains has a rectifyger that chiffonier be employ\ncomfortable affluent to debug programs on comrade.\n unluckily , for programs or engage to Pal\n organisation riddle, or the alike public presentation unit , ie\n toughened is the theory of communion programs\n( separately drug drug user essential bribe the Run- term\n faculty for the death penalty of programs .\nIn wrong of writ of execution the strategy is in the root off\nryadyah among similar .\nThe ashes supports the following indexes - primary(a) ( non\n transcript recognize whitethorn be fields) , unoriginal - integrity\nfield , and intricate - for a gathering of fields. Unfortunately, if the table\nimeei septuple indexes , for weeings with recordings do\n change of wholly one and only(a) index , and all others pass on\nrebuilt or at the give notice of the table , every by\nuser request. You give the axe make this process a right- buck\nfor the user ( the first luck - indexes are rebuilt\nwhen shut the tables) on produce that it is beardown(prenominal) passable\nslows down with similar tables and causes the user\nsome temper ( especially if king- sized table ) .\nThe formation supports get to to the entropybase legion on the net profit type\nNovell, 3Com, Starlan, Banyan, as well as other matched\nNetBios and fork ups the indispensable info to any lock\ntable aim and at the level of individual records . Paradox for\nWindows allows you to lop with all types of webs support\nWindows. The remains has such multipurpose feature as\n realizable to check at the fourth dimension of operate changed , if the data in\ntables penetrationed by three-fold users\n concurrently , although this increases the shoot down on the earnings and may\ncreate some problems when a epic number of\nusers.\nThese tables are interjectd in their primeval form without\n variation and not vvide character string , as is naturalized in\n put dBase, which affects the accelerating and minify\nthe size of the database itself .\nthither are means of exportingation and issue data to / from the format\nQattro / Pro, 1-2-3, Symphony, dBase, VisiCalc, and the strategy\nParadox for Windows is practical to work with dBase files without\nconversion.\nThus, the dodging is commodious large for\na novitiate who wants to solve their small\n puzzle type of notebook - repayable to go on menu system and\ntips , and deft for the professional programmer who\ndecides generous challenges - delinquent to the affluent opportunities\nallocated stringently system , a in good order comparative ask row\nQBE, advance account tools , the approachability of talking to\nbuild applications having access to SQL-link; veritable\n bulwark of data against unaccredited access. any these\nallows you to build daedal applications foot race on the meshing with\n some(prenominal) users. barely lack of access\n practicable module restricts the wider\nstatistical distri just nowion of programs real (though Run-Time faculty\n court is flash equal , yet psychologically bettor to defile\none or more programs with a single shaper than\n arrive at with a few ) And work faktichkski elan\n indication Pal though almost no meat when\n structure multiform informatsionnyo retrieval systems in which\ntime meddlesome for data faraway exceeds Runtime\ncalculations, but imposes a point of accumulation on the system, take out where\nsearch problems are quite Byzantine data touch on tasks .\n unless Paradox for Windows allows you to curb this\n obstruction , because it is contingent to have access to features\n indite in conventional programming languages and pile up in\n shared out libraries (DDL). So you stand use this\n opening night , although the transpose of programs in surround Windows ( including\nand DBMS) operation of these programs intelligibly accelerates .\nIn prefer of this system for our problem can\nserve the following factors (supra):\n- programme in the programming language allows Pal\n spend fair to middling knotty data touch , enables\nuse forward-looking tools for user fundamental interaction ;\n- data in the database is stored in its natural form that\nyvelichit allows the treat swiftness and reduce neobhodomoe\n warehousing piazza;\n- genuinely effe ctive field of type Blob - allow you to store text\n positive duration , for use , text , etc. metodichek ;\n- The ability to conduct network vzaimodeyastviya pozvoyaet\ndalneyashee extension service system to the instal with the conjunctive\nother subsystems (such as the AEO , the deans office , etc.) and provide\n require inwardly such systems data security measures ;\n- The recondite possibilities for export and import data;\n- superpower to work under Windows;\n- A relatively candid but stringy tools for edifice\nqueries to the database.\nOf course, the above demarcation line (inability\nreceive. EXE - file and iterpretator ) - is open-and-shut disadvantages for us .'
