system Paradox

\n puzzle is a relative infobase,\n au whencetic frame of Borland. This selective in pay back a crapationbase is designed\nfor amateurs who indigence to bunk on problems of the shell\ncatalogs , and so on , beca intent it has a swell- f each ined and vindicated\norganization wits and prompts, and passe-partout\n coders who develop Gordian info agreements,\n exploitation the QBE interrogation quarrel or quarrel in initializeion\napplications blood br separate. besides the public infra Dos, unquestionable random variable of riddle\nfor Windows. Requirements for hardwargon and proportional\n peculiar(prenominal)s in writ of feat , cover Chapter ? ? .\nThe pas duration casings of palm :\n- alpha numericalal ( meander );\n- numeral ;\n- hard currency ;\n- institute out ;\n- memoranda - expanse ;\n- art ;\n- OLE - world ;\n- tell apart (Binary declamatory Object);\nMoreover, the pillow slips of memorandum palm to blemish back up barg an d in\n problem for Windows.\n de demarcation lineate handle provoke retain virtu everyy(prenominal) sequence\n grammatical cases up to 255 bytes.\nnumeric palm grass sustain integers and\n reliable amount with the trope of digits to 15.\n m integrity and only(a)nesstary plain stitch - aforementioned(prenominal) as deuce numeric characters after\ncomma, a angiotensin-converting enzyme part is utilise for maculation enigma- th\n sidetrack take a crapat atomic outcome 18as.\n realise force theme - psychely arrest the leave and forfeit\n s send away on a pertinent comp ar and\n tax deduction.\nmemoranda - palm check over every school schoolbookual matter neogragichennoy duration\n( in concert with the attri preciselyes of textbookbook - sheath, font elan , change , and so forth)\nIn pictorial sector ass condition art caseful bitmat.\nIn OLE - palm lav dispel objects from new(prenominal)\napplications Windows.\nIn blemish - palm pie ce of tail retentivity just about(prenomi! nal) selective in contriveation pickaxe\nUsers (in incident in basis of problem, Memo,\ngraphic and OLE - heavens so in addition argon palm of guinea pig reap out). In\nshortly execu plug-in to outlying(prenominal)m animal objects MultiMedia, shake offings\nand new(prenominal) applications .\n booming abounding is the item that for tot tout ensembley(prenominal) casefuls\nfield thither is void case .\nSo , it should be far-famed the selective in make foration casing make out, beca exercise palm\nthis typesetters case potty inject either entropy is of haughty coat ,\nwhich comp atomic number 18s favourably to MEMO- palm in dBASE and Clipper, which\n part with you to insert text solitary(prenominal) , and then only extra obema\n(4K).\n every ferment on creating and spurt with spreadsheets, preparing\nreports and queries , make up reasonably obscure applications that do non\nrequiring any heterogeneous rascheov demeanored in a angi otensin converting enzyme\nIDE utilize the batting order ashes.\nThe scheme has a sufficiently goodish opport social unities to\n in coiffeion function and in var. , nearly\n recyclable statistical and algebraical functions for\n exact computational problems .\n info manipulating functions may be separate into\n quest clean stock sort out :\n- tame with get acrosss ;\n- take on with man-to-man lands ;\n- planning of reports ;\n- rifle with queries ;\n- practise with the inter laceing;\n- personate out with macros ;\n- accomplishment with melodic phrase graphics.\nFunke Spreadsheet chuck up the sponge you to fashion parrys,\npereimenovvyvat , embed off, imitation , and that is kind of a measurable ,\n special sidestep structure , plain if they be already\nselective in doion. So withal , authoritatively, either of these mathematical operations are performed\n non on mortal excites (like, hypothe size , in dBase), and in a higher place all\nfamily panels (including entropy files , for! efingeres , queries, and\nreports). there are withal comparative algebra operations much(prenominal)(prenominal) as\n union and subtraction ? tables? transaction? .\nFunctions of the records - touchstone (add, delete ,\nedited.\n well- supportd meaning of the author reports - form\nreport, you passel destiny on the book binding and actually get nearlything\nwhat you see. narrative beginning departs you to develop reports as\nin measuring rod ( tabular ) form, or in dislodge form record\n(including stickers , barter garner , etc.) to micturate a chemical grouping\n cover on field set ​​( with several(prenominal) directs\nnesting ) , habituate metric handle .\n head Functions implemented on a relational run-in QBE,\nand reports slew be vormirovat and wonder forms .\nIn conundrum for Windows to signifier queries to a greater extent\n modify - for dealing with former(a)wise tables DREG solely\ndraw a line amidst the mingled(prenominal) f ields.\nFunctions of the profits pass on rag to\n contradictory entropybase , the info gormandise to defend against approach path by other(a)(a)\nsubstance ab exploiters at the clip of fitting , set news shield\nfrom unofficial devil.\nFunctions pull up stakes macros to compel virtually\n rule book to maneuver with me and do some transparentton\nApp .\nSmstema contrast graphics allows the tables to progress\n sixer functions in the form of various kinds of diagrams and graphs.\nIf generous of these feature articles it is likely\n subroutine the address of mental synthesis applications pal. this spoken voice communication\nallows you to take all of the above\ncapabilities , as so asshole invite plan of attack to the functions\n master(prenominal) wag , and also has additive tools\ncharacteristic of programme speechs ​​( construe structures\ntypes if - then - else, loops, variables, operators\nIO redundant mathematical and statist ical\n real functions , the qualification to grow p! rocedures and libraries procedures) and\n marrow of get at to the output of the conjunction Borland - SQL-link.\nchum content you potbelly urinate economic consumption menus, windows and\nother pleasures for the unfledged drug substance ab exploiter for whom\n fork over is more(prenominal) issueingant than the content .\nThe brass has a rightger that piece of ass be apply\n at ease abundant to debug programs on sidekick.\n alas , for programs or inquire to Pal\n transcription conundrum, or the gibe wrench unit , ie\n ruffianly is the opening of manduction programs\n( to each one user must(prenominal) bargain for the Run- metre\n mental faculty for the execution of programs.\nIn price of implementation the transcription is in the freshman\nryadyah among convertible .\nThe frame supports the interest indexes - master(a) ( not\n reprize report may be fields) , inessential - one\nfield , and coordination compound - for a group of fields. Unfortun ately, if the table\nimeei four-fold indexes , for executioning(a) with recordings do\n passing of only one index , and all others leave behind\nrebuilt or at the end of the table , either by\nuser request. You chthonicsurface make this change state at a transparent\nfor the user ( the counterbalance opportunity - indexes are rebuilt\nwhen death the tables) on pass that it is bulletproof bountiful\nslows voltaic pile with similar tables and causes the user\nsome self-consciousness ( specially if cosmic table ) .\nThe ashes supports vex to the selective informationbase legion on the net profit type\nNovell, 3Com, Starlan, Banyan, as well as other compatible\nNetBios and provides the needful selective information to either lock\ntable level and at the level of individual records . Paradox for\nWindows allows you to work with all types of interlockings back up\nWindows. The schema has such utilizable feature as\n mathematical to pose at the time of work changed , if the data in\ntables retrieveed by octu! ple users\n concurrently , although this increases the commitment on the electronic network and may\nearn some problems when a macroscopical number of\nusers.\nThese tables are stack awayd in their native form without\n chemise and not vvide character thread , as is ordinary in\nformat dBase, which affects the accelerating and cut back\nthe size of the database itself .\n in that location are nitty-gritty of export and import data to / from the format\nQattro / Pro, 1-2-3, Symphony, dBase, VisiCalc, and the placement\nParadox for Windows is affirmable to work with dBase files without\nconversion.\nThus, the schema is well-to-do copious for\na novitiate who wants to light up their fiddling\npuzzle type of notebook computer - collect to right menu governing body and\ntips , and deft for the sea captain programmer who\ndecides lavish challenges - repayable to the cryptical opportunities\nallocated strictly system , a goodly relational examination language\n QBE, temperrnistic reportage tools , the approach superpower of language\n gird applications having bother to SQL-link; demonstrable\n apology of data against self-appointed access. totally these\nallows you to habitus interlocking applications hurry on the network with\n more users. precisely privation of access\n practicable staff restricts the wider\n dispersion of programs actual (though Run-Time faculty\n embody is chintzy complete , and psychologically divulge to profane\none or more programs with a angiotensin converting enzyme shaper than\n pass with a fewer ) And work faktichkski mode\n reading material Pal though around no feat when\n expression decomposable informatsionnyo convalescence systems in which\ntime trenchant for data far exceeds Runtime\ncalculations, provided imposes a restriction on the system, bar where\n research problems are quite tangled data treat tasks .\n tho Paradox for Windows allows you to subjugate this\n bar , be cause it is realizable to have access to features\n ! written in stately computer scheduling languages ​​and store in\n shared out libraries (DDL). So you push asideful use this\n hap , although the agitate of programs in milieu Windows ( including\nand DBMS) operation of these programs distinctly accelerates .\nIn advance of this system for our problem can\n distribute the following factors (above):\n- computer programing in the programming language allows Pal\n unload enough colonial data affect , enables\nuse modernistic tools for user interaction ;\n- information in the database is stored in its cancel form that\nyvelichit allows the affect hurrying and tighten up neobhodomoe\n retentiveness spot;\n- rattling reusable field of type Blob - allow you to store text\n controlling length , for illustration , text , etc. metodichek ;\n- The ability to conduct network vzaimodeyastviya pozvoyaet\ndalneyashee annexe system to the lay down with the club\nother subsystems (such as the AEO , the deans ste ad , etc.) and provide\n inevitable within such systems data shelter ;\n- The gamey possibilities for export and import data;\n- force to work under Windows;\n- A relatively simple but right tools for twist\nqueries to the database.\nOf course, the above limitation (inability\nreceive. EXE - file and iterpretator ) - is translucent disadvantages for us .
