Ríomhairí, Ríomheolaíocht Sreabhadh sonraí ar Léaráid den Sreabhadh Sonraí ar féidir é a dhianscaoileadh ag leibhéal níos ísle ina dhá shreabhadh sonraí ar leith nó breis.
Computers, Computer Science A data flow on a Data Flow Diagram which can be decomposed at a lower level into two or more separate data flows.

Ríomhairí, Ríomheolaíocht Cineál ailtireacht ríomhairí ina mbíonn líon áirithe próiseálaithe atá saor ó phróiseáil srathach de shaghas ar bith. Ina ionad sin, téann gach próiseálaí ag obair de réir mar a chuireann próiseálaithe eile sonraí ar fáil agus roinneann sé toradh a chuid oibre ar phróiseálaithe eile nuair a bhíonn sé críochnaithe.
Computers, Computer Science 1. A type of computer architecture involving a number of processors that are freed from any serial form of processing. Instead, each processor goes to work as data becomes available from other processors and shares the results of its work with other processors when it has finished. 2. (In SSADM) One of the elements of Data flow diagrams. The data flow shows a passage of data between two other elements, process, data store or external entity. At the lowest level, the data flows are simple flows, but at the higher levels they may be grouped together as composite flows, for ease of drawing.
Déanfar an staidreamh a bheidh le táirgeadh a ghrúpáil lena tharchur chuig an gCoimisiún (Eurostat) i gcomhréir leis na sreafaí sonraí seo a leanas...
The statistics to be produced shall be grouped for transmission to the Commission (Eurostat) in accordance with the following data flows...

Ríomhairí, Ríomheolaíocht An stóras ar an DFD Loighciúil do na míreanna sonraí uilig a bhaineann le hábhar amháin. Ní hionann é agus na stórais fhisiciúla sonraí, áit ar féidir ábhar amháin, e.g., orduithe, a choimeád i bhformáidí éagsúla agus in áiteanna éagsúla i rith shaol aon tarlaithe amháin.
Computers, Computer Science The repository on the Logical DFD for all data items belonging to one subject. Unlike the physical data stores, where one topic, e.g., orders, could be held in many formats and many places during the life of any one occurrence.

Ríomhairí, Ríomheolaíocht Ceann de na heilimintí comhpháirteacha i Léaráid den Sreabhadh Sonraí. Cur síos é ar aon áit sa chóras ina stóráiltear nó ina mbailítear sonraí. D'fhéadfadh gur meán leictreonach a bheadh i gceist ar nós comhad diosca/téipe, nó d'fhéadfadh gur meán stórála láimhe a bheadh ann ar nós comhadchaibinéad, nó comhad cárta-innéacs. Tugtar stóras sonraí freisin ar bheart foirmeacha i bhfáiscín docht ag fanacht ar ghníomhaíocht éigin. Ar Léaráid den Sreabhadh Sonraí, ní mór próiseas amháin ar a laghad, agus breis is ceann de ghnáth, a thaispeáint ag rochtain gach stóras sonraí, chun sonraí a chruthú, agus a úsáid.
Computers, Computer Science One of the component elements of a Data flow diagram. It represents any place in the system where data is stored or collected. It may be an electronic medium such as a disk/tape file, or it may be a manual storage method such as a filing cabinet, or card-index file. A batch of forms in a bulldog clip waiting to be actioned also counts as a data store. On a Data flow diagram, it is necessary to show each data store being accessed by at least one process, and usually more, both for creating the data, and for using it.

Ríomhairí, Ríomheolaíocht Stóras sonraí a choimeádtar go sealadach roimh a bpróiseáil, agus a scriostar ansin. Ní dócha go n-áireofaí a leithéid sin de shonraí ar Struchtúr Loighciúil Sonraí. Is d'áisiúlacht riaracháin is mó a úsáidtear na stórais seo, agus is minic a cheiliúrann siad ón Léaráid den Sreabhadh Sonraí ag am loighcithe.
Computers, Computer Science A store of data that is held temporarily before being processed, and is then deleted. Such data is not likely to be included on a Logical Data Structure. These stores are mostly used for administrative convenience, and frequently vanish from The Data flow diagram at logicalization.

gu struchtúir dhinimiciúil sonraí, ai struchtúir dhinimiciúla sonraí
Ríomhairí, Ríomheolaíocht Struchtúr sonraí a mb'fhéidir go n-athródh a thréithe eagraíochtúla i rith a shaoil. Go minic baineann solúbthacht lena leithéid seo struchtúir, e.g. liostaí nasctha, ach is minic a laghdaítear éifeachtúlacht rochtana ar eilimintí an struchtúir mar gheall air sin. Tá dhá ghné ar leith a idirdhealaíonn struchtúir dhinimiciúla ó struchtúir statacha sonraí. Ar an gcéad dul síos, ní féidir a thuilleadh an t-eolas struchtúrtha ar fad a bheith i gceanntásc; ní mór do gach eilimint eolas a bheith ann a thugann gaol loighciúil dó le heilimintí eile an struchtúir. Ar an dara dul síos, níl sé oiriúnach i gcónaí bloc aonair stórála leanúnaigh a úsáid, agus más ea is gá scéim bainistíochta stórála a sholáthar ag am rite.
Computers, Computer Science A data structure whose organizational characteristics may change during its lifetime. The adaptability afforded by such structures, e.g. - linked lists, is often at the expense of decreased efficiency in accessing elements of the structure. Two main features distinguish dynamic structures from static data structures. Firstly, it is no longer possible to have all structural information in a header; each element will have to contain information relating it logically to other elements of the structure. Secondly, using a single block of continuous storage is often not appropriate, and hence it is necessary to provide some storage management scheme at run-time.

Ríomhairí, Ríomheolaíocht Ceann de thrí amharc ar an gcóras. Taispeánann sé riachtanais faisnéise na heagraíochta trí aonáin agus na gaoil eatarthu a aithint, i dtéarmaí na ngníomhaíochtaí feidhmiúla gnó.
Computers, Computer Science One of the three views of the system. It shows the information requirements of the organization by identifying entities and the relationships between them, in terms of the business functional activities.

Ríomhairí, Ríomheolaíocht Samhail fhoirmiúil de na gaoil oird agus inrochtaineachta i measc míreanna sonraíochta gan tagairt dá gcumraíocht stórála iarbhír.
Computers, Computer Science A formalized representation of the ordering and accessibility relationships among data items without regard to their actual storage configuration.

Ríomhairí, Ríomheolaíocht B'fhearr treoracha cóipeála sonraí a thabhairt ar threoracha aistrithe sonraí ach tá an téarma aistriú sonraí bunaithe cheana. Nuair a deirimid go bhfuil an t-ábhar atá i suíomh 2000 sa chuimhne aistrithe go tabhall éigin, is éard a bhíonn i gceist againn beagnach i gcónaí ná go bhfuil cóip chomhionann cruthaithe ansin agus go bhfuil an bunábhar fós gan chorraí i suíomh 2000.
Computers, Computer Science Data movement instructions would better be called data duplication instructions, but the term data movement is already established. When we say that the contents of memory location 2000 have been moved to some register, we almost always mean that an identical copy has been created there and that the original is still undisturbed in location 2000.
