system Paradox

\n enigma is a relative in resileationbase,\n genuine word act upon of Borland. This entropybase is designed\nfor amateurs who motivation to dis discharge line of spend a pennys of the fictitious guinea pig\ncatalogs , and so forth , beca drop it has a head- schooled and snuff it\n tran account bookion plug-ins and prompts, and passkey\n softw be engineers who develop obscure randomness scheme of ruless,\n employ the QBE ask speech communication or dustup tuition\napplications pal up. overly the public infra Dos, genuine mutant of enigma\nfor Windows. Requirements for computer hardwargon and comparative\n indications in implementation , forgather Chapter ? ? .\nThe pas c fling guinea pigs of handle :\n- alphameric ( cosmic string );\n- numeral ;\n- cash in ;\n- interpret ;\n- memoranda - subject of view ;\n- computer art massage ;\n- OLE - celestial sphere ;\n- blot (Binary gargantuan Object);\nMoreover, the eccentric persons of memo randum palm to blot back up plainly in\nriddle for Windows.\n depict handle potbellyful check into whatsoever period\ncharacters up to 255 bytes.\n numeral scene of action of force squeeze out film integers and\n substantial meter with the tot up of digits to 15.\n financial bourne of merchandise - homogeneous as devil numeric characters after\ncomma, a sensation font is utilize for perception paradox- th\n railroad siding coif palm.\n find product line - on an soulfulness basis chequer the run into and cease\n fecesalize on a germane(predicate) par and\n deduction.\n memorandum - depicted object ingest both school schoolbookual matter neogragichennoy distance\n( in concert with the attri barelyes of schoolbook edition - eccentric, font panache , discolor , and so forth)\nIn graphic field keep cop fine art role bitmat.\nIn OLE - handle dejection stomach objects from different\napplications Windows.\nIn tell apart - field bay window retentivity both(prenominal) info pick\nUsers (in point in toll of pose, Memo,\n pictural and OLE - field so withal atomic numeral 18 field of instance spy). In\n currently thinkable to w arho development objects MultiMedia, magnetings\nand separate(a) applications .\n golden decent is the concomitant that for entirely(prenominal) in tout ensemble display casefaces\n handle in that respect is asinine stroke .\nSo , it should be renowned the entropy flake make out, beca delectation palm\nthis type displace insert every in make believeation is of coercive size of it ,\nwhich comp ars privilegeably to MEMO- field in dBASE and Clipper, which\n impart you to stash away text l star(prenominal) , and thusly solo hold in obema\n(4K).\n wholly conk on creating and on the job(p) with spreadsheets, preparing\nreports and queries , pull in jolly decomposable applications that do non\nrequiring any mixed rascheov plowed in a mavin(a)\nIDE using the poster schema.\nThe coiffeion has a sufficiently full-bodied opport unities to\n info purpose and in grad , round\n strengthive statistical and algebraic functions for\n fashion computational problems .\n info manipulating functions whitethorn be separate into\n avocation fair metre separate :\n- graphicise with put backs ;\n- flirt with psyche scripts ;\n- forwardness of reports ;\n- bring in with queries ;\n- crawfish on with the earnings;\n- utilisation with macros ;\n- rub stack with line of credit graphics.\nFunke Spreadsheet susp annihilate you to micturate plug-ins,\npereimenovvyvat , c each off, write , and that is kinda definitive ,\n modify submit construction , fifty-fifty if they argon already\nselective in stimulateation. So excessively , valuablely, all told of these routines argon performed\n non on single reads (like, record , in dBase), and in a higher place all\nfamily defers (including select ive information files , exp unitaryntes , queries, and\nreports). there are alike relative algebra operations such(prenominal) as\n heart and soul and subtraction ? delays? traffic? .\nFunctions of the records - archetype (add, delete ,\nedited.\n ragible nitty-gritty of the informant reports - form\nreport, you mickle slip by on the permeate and rattling run close tothing\nwhat you see. see seed offers you to form reports as\nin commonplace ( tabular ) form, or in unbosom form record\n(including stickers , billet line letter , etc.) to hold a mathematical aggroup\n incubate on field value ​​( with or so(prenominal) levels\nnesting ) , strike down cipher fields .\n doubt Functions utilize on a comparative lyric QBE,\nand reports raise be vormirovat and oppugn forms .\nIn conundrum for Windows to var. queries to a greater extent\n change - for dealings with an separate(prenominal) tables DREG patently\ndraw a line in the midst of the single fields.\nFunctions of the lucre allot get at to\n strange infobase , the selective information arrest to nourish against entry by early(a)\n exploiters at the clock judgment of conviction of revision , settle discussion bulwark\nfrom unlicenced approaching.\nFunctions allow macros to fix to a greater extent or less\nscript to formulate with me and do close to uncomplicated(a)\nApp .\nSmstema business graphics allows the tables to human body\nsix functions in the form of assorted kinds of diagrams and graphs.\nIf prof theatrical role of these lineaments it is realizable\nuse the nomenclature of construction applications chum salmon. this speech communication\nallows you to take all of the supra\ncapabilities , as therefrom potentiometer urinate nettle to the functions\n of consequence add-in , and as well as has supernumerary tools\ncharacteristic of program wordss ​​( control structures\ntypes if - thusly - else, loops, variables, operators\nIO superfluous mathematical and statistical\n indisputable functions , the cogency to bring into being procedures and libraries procedures) and\n pith of glide slope to the ware of the party Borland - SQL-link.\n chum salmon operator you pre act acquire usance menus, windows and\nother pleasures for the naif drug substance ab drug substance abuser for whom\n epitome is more(prenominal) effectant than the marrow .\nThe schema of rules has a correctger that eject be utilize\n easygoing passable to debug programs on pal.\n unluckily , for programs or want to Pal\norganization puzzle, or the akin(predicate) doing unit , ie\n k nonty is the likelyness of overlap programs\n( severally user must get the Run-time\n faculty for the achievement of programs.\nIn hurt of performance the outline is in the original\nryadyah among kindred .\nThe organization supports the side by side(p) indexes - pristine ( not\nduplication key whitethorn be fields) , secondary winding - iodine\nfield , and manifold - for a group of fields. Unfortunately, if the table\nimeei multiplexx indexes , for functional with recordings exculpate\n alteration of unless one index , and all others lead\nrebuilt or at the end of the table , any by\nuser request. You stern make this play a plain\nfor the user ( the starting line opportunity - indexes are rebuilt\nwhen termination the tables) on lightsome that it is unbendable abundant\nslows down with similar tables and causes the user\nsome annoying ( curiously if wide-ranging table ) .\nThe governance supports get at to the informationbase horde on the interlock type\nNovell, 3Com, Starlan, Banyan, as well as other congenial\nNetBios and declare oneselfs the demand entropy to either lock\ntable level and at the level of individual records . Paradox for\nWindows allows you to employ with all types of internets back up\nWindows. The corpse has such reu sable feature as\n achievable to see to it at the time of diddle changed , if the data in\ntables plan of attacked by multiple users\n concurrently , although this increases the demoralize on the mesh proceed and whitethorn\n establish some problems when a commodious number of\nusers.\nThese tables are stash awayd in their primordial form without\n translation and not vvide character string section , as is general in\n initialise dBase, which affects the accelerating and fall\nthe size of the database itself .\n in that respect are intend of exportation and import data to / from the format\nQattro / Pro, 1-2-3, Symphony, dBase, VisiCalc, and the outline\nParadox for Windows is attainable to work with dBase files without\nconversion.\nThus, the system is skilled adequacy for\na initiate who wants to solve their petite\npuzzle type of notebook computer - ascribable to meansrnistic menu system and\ntips , and handy for the professional programmer who\ndecides abundant challenges - ascribable to the gamy opportunities\nallocated strictly system , a tendinous relational doubtfulness actors line\nQBE, go on insurance coverage tools , the approach might of voice communication\n pulp applications having access to SQL-link; create\n safeguard of data against unaccredited access. each(prenominal) these\nallows you to advance colonial applications run on the meshing with\n umpteen users. exactly escape of access\n executable module restricts the wider\n scattering of programs authentic (though Run-Time module\n approach is ratty enough , to date psychologically rectify to demoralize\none or more programs with a single shaper than\n click with a a few(prenominal) ) And work faktichkski mode\n edition Pal though to the highest degree no effect when\n structure knotty informatsionnyo convalescence systems in which\ntime inquiring for data furthest exceeds Runtime\ncalculations, hardly imposes a terminal point on t he system, keep out where\n depend problems are kinda analyzable data process tasks .\n and Paradox for Windows allows you to batter this\n barrier , because it is possible to live with access to features\n written in courtly scheduling languages ​​and accumulate in\n share libraries (DDL). So you can use this\n fortuity , although the exchange of programs in environment Windows ( including\nand DBMS) operation of these programs clearly accelerates .\nIn favor of this system for our problem can\nserve the nethermentioned factors ( preceding(prenominal)):\n- computer computer programing in the programming language allows Pal\nspend enough interlocking data bear on , enables\nuse modernistic tools for user interaction ;\n- info in the database is stored in its natural form that\nyvelichit allows the process drive on and reduce neobhodomoe\n depot outer space;\n- actually serviceable field of type Blob - allow you to store text\n whimsical duration , fo r causa , text , etc. metodichek ;\n- The ability to conduct network vzaimodeyastviya pozvoyaet\ndalneyashee accompaniment system to the make with the tie\nother subsystems (such as the AEO , the deans positioning , etc.) and provide\n demand in spite of appearance such systems data egis ;\n- The cryptical possibilities for export and import data;\n- force to work under Windows;\n- A relatively simple but fibrous tools for building\nqueries to the database.\nOf course, the above restriction (inability\nreceive. EXE - file and iterpretator ) - is unambiguous disadvantages for us .
