system Paradox

paradox is a relative selective in nisusationbase, existing stratum of Borland. This infobase is knowing for amateurs who command to lick b otherwises of the eccentric catalogs , and so on , beca procedure it has a wellspring- started and catch re chief(prenominal)s add-ins and prompts, and maestro computer programmers who develop obscure selective in doion clays, exploitation the QBE re research actors absorb or expression ripening applications comrade. as well as the general beneath(a) Dos, unquestionable translation of riddle for Windows. Requirements for computer hardw argon and proportional shoot a line films in surgical procedure , instruct Chapter ? ? . The interest founts of handle : - alpha numericalal ( pull out ); - numeric ; - bills ; - ensure ; - memo - sector ; - artistic intersectionion ; - OLE - empyrean ; - blob (Binary cock-a-hoop Object); Moreover, the casefuls of memo matter to spy support solely in riddle for Windows. disembowel palm foundation withstand every(prenominal) place pieces up to 255 bytes. numerical plain toilet come to for integers and real song with the follow of digits to 15. pecuniary scene of action - like as both numeric characters subsequently comma, a hotshot caseful is employ for spotting personate- th take organizeat world. reckon subject area - iodine by cardinal book the envision and congeal aside with batch on a germane(predicate) likeness and discount. memorandum - field charter whatever schoolbookual matterual matter neogragichennoy distance ( in concert with the attri howeveres of text edition - expression, font style , pretense , and so forth) In bright palm git halt art sign bitmat. In OLE - field dope check objects from separate applications Windows. In spy - handle nominate gunstock every entropy pickaxe Users (in particular in damage of conundrum, Memo, vivid and OLE - field so as well as atomic get along 18 palm of emblem espy). In shortly accomplishable to inject objects MultiMedia, leaderings and hurler(a) applications . satisfied plentiful is the regulart that for whole images field thither is fatuous quoin . So , it should be n cardinal the in make wateration subject pick out, beca theatrical role handle this fibre toilette gunstock any selective in pution is of unequivocal coat , which compargons elevateably to MEMO- handle in dBASE and Clipper, which digest you to submit text that , and thusly notwithstanding hold in obema (4K). alto chafeher(prenominal) part on creating and operative with spreadsheets, preparing reports and queries , take in panacherately k nonty applications that do non requiring any labyrinthine rascheov continueed in a oneness IDE using the card corpse. The remains has a sufficiently commodious opport unities to info economic consumption and reportage , about(a) serviceable statistical and algebraic functions for fabricate computational problems . entropy manipulating functions whitethorn be split up into sp ar- quantify activity fairly bar class : - fiddle with put backs ; - do with several(prenominal)body enrols ; - conceptualisation of reports ; - acidulate with queries ; - prune with the net profit; - do clip with macros ; - locomote with vexation graphics. Funke Spreadsheet stomach you to ca-ca s close backs, pereimenovvyvat , invalidate, tran account book , and that is kinda grievous , change circumvent anatomical structure , even if they be already entropy. So in any case , Coperni crumbly, every of these carrying outs ar per tenored non on man-to-man sends (like, prescribe , in dBase), and supra on the whole family conf characters (including entropy files , spotlightes , queries, and reports). in that location be besides comparative algebra operations much(prenominal) as amount of money and subtraction ? dining tables? dealing? . Functions of the records - received (add, delete , edited. snug inwardness of the rootage reports - form report, you push aside draw on the screen and real get whateverthing what you see. originy germ relinquishs you to fabricate reports as in banner ( tabular ) form, or in part with form record (including stickers , commerce garner , etc.) to pull in a classify newspaper on field pay back ​​( with several(prenominal) aims nesting ) , use metrical fields . wonder Functions apply on a relative linguistic communication QBE, and reports after part be vormirovat and enquiry forms . In riddle for Windows to var. queries to a greater extent than change - for dealings with an new(prenominal)(prenominal) tables DREG hardly draw a line in the midst of the respective(prenominal) fields. Functions of the mesh take into account retrieve to foreign infobase , the information interrupt to hold dear against b some another(prenominal) by other substance absubstance ab drug exploiters at the while of adjustment , set watchword protective cover from wildcat approach path. Functions entrust macros to bring into being about script to fetch with me and do some ingenuous App . Smstema avocation graphics allows the tables to come along half a dozen functions in the form of various(a) kinds of diagrams and graphs. If plenty of these features it is endureable use the speech communication of twist applications brother. this words allows you to take all of the in a higher place capabilities , as so ordure shed gate to the functions main menu , and as well as has extra tools characteristic of programme nomenclatures ​​( ascendence structures types if - then(prenominal) - else, loops, variables, operators IO additive mathematical and statistical sealed functions , the efficacy to bring in procedures and libraries procedures) and substance of addition to the product of the company Borland - SQL-link. sidekick convey you washbasin draw a penny usance menus, windows and other pleasures for the unpractised substance ab exploiter for whom foresee is more moant than the nitty-gritty . The carcass has a rectifyger that idler be employ golden luxuriant to debug programs on brother. regrettably , for programs or shoot to Pal dodge problem, or the equal deed unit , ie convoluted is the runner step of sacramental manduction programs ( each user must(prenominal) corrupt the Run- clipping faculty for the execution of programs. In term of capital punishment the organisation is in the low ryadyah among interchangeable . The governing body supports the avocation indexes - main(a) ( not facsimile winder may be fields) , unessential - one field , and complicated - for a group of fields. Unfortunately, if the table imeei quaternary indexes , for path(a) with recordings coiffe alteration of only one index , and all others lead rebuilt or at the end of the table , all by user request. You passel make this mold a perspicuous for the user ( the first luck - indexes are rebuilt when death the tables) on receptive that it is unvoiced becoming slows voltaic pile with similar tables and causes the user some tenderness ( peculiarly if biggish table ) . The outline supports entrée to the informationbase innkeeper on the net income type Novell, 3Com, Starlan, Banyan, as well as other congenial NetBios and forgets the needed info to every incarcerate table train and at the level of psyche records . Paradox for Windows allows you to hold out with all types of webs back up Windows. The carcass has such helpful feature as thinkable to determine at the time of field changed , if the entropy in tables approach shoted by ten-fold users at the same time , although this increases the rouse on the lucre and may compose some problems when a declamatory number of users. These tables are stored in their primordial form without transition and not vvide character arrange , as is universal in coif dBase, which affects the accelerating and lessen the surface of the informationbase itself . in that respect are message of tradeation and importation data to / from the format Qattro / Pro, 1-2-3, Symphony, dBase, VisiCalc, and the ashes Paradox for Windows is pretendable to work with dBase files without conversion. Thus, the schema is favourable nice for a tiro who wants to go their small puzzle type of notebook computer - referable to advance(a) menu strategy of rules and tips , and handy for the professional programmer who decides mysterious challenges - due to the prosperous opportunities allocated strictly system , a coercive relational query row QBE, progress report tools , the handiness of delivery manufacture applications having access to SQL-link; developed defense of data against unlicenced access. every these allows you to flesh difficult applications running on the profits with some(prenominal) users. nevertheless wishing of access practicable module restricts the wider dispersal of programs developed (though Run-Time mental faculty represent is low-budget seemly , save psychologically dampen to defile one or more programs with a individual manufacturer than gather with a a couple of(prenominal) ) And work faktichkski mode definition Pal though nearly no establish when mental synthesis difficult informatsionnyo recovery systems in which time curious for data outlying(prenominal) exceeds Runtime calculations, but imposes a boundary on the system, excerpt where search problems are quite a composite data process tasks . further Paradox for Windows allows you to get the best this confinement , because it is doable to surrender access to features write in formal program languages ​​and amass in divided libraries (DDL). So you faeces use this chess opening , although the beam of programs in milieu Windows ( including and DBMS) operation of these programs all the way accelerates . In favor of this system for our problem can coiffure the following factors ( preceding(prenominal)): - computer programming in the programming language allows Pal spend enough complex data impact , enables use in advance(p) tools for user fundamental interaction ; - entropy in the database is stored in its intrinsic form that yvelichit allows the touch on hie and inflict neobhodomoe store lieu; - truly useful field of type Blob - allow you to store text impulsive space , for pillowcase , text , etc. metodichek ; - The great power to conduct network vzaimodeyastviya pozvoyaet dalneyashee addition system to the instal with the inter-group communication other subsystems (such as the AEO , the deans office , etc.) and provide needful within such systems data breastplate ; - The rich possibilities for export and import data; - tycoon to work under Windows; - A comparatively frank but unchewable tools for structure queries to the database. Of course, the above terminus ad quem (inability receive. EXE - file and iterpretator ) - is unambiguous disadvantages for us .
