Ríomhairí, Ríomheolaíocht Tá an tSamhail Loighciúil de Shonraí faoi réir trasfhoirmiú atá bunaithe ar rialacha láimhe áirithe. Tá siad seo neamhspleách ar aon timpeallacht infheidhmithe ar leith, ach ba chóir go mbeidís inchurtha in oiriúint do tháirge sonraithe ar bith. Ba chóir dó a bheith gar go leor don dearadh deireanach le go rithfí cleachtaí uainithe agus tomhais air. Tá dhá leagan ann den Dearadh Céadiarrachta Sonraí: An dearadh atá neamhspleách ar chur i ngníomh, a leantar le dearadh céadiarrachta de réir rialacha a chuireann an timpeallacht roghnaithe ar fáil. Fágtar an dara ceann ar lár go minic, ag brath ar chleachtadh an dearthóra, nó ar riachtanais agus ar chastacht an DBMS roghnaithe.
Computers, Computer Science The Logical Data Model is subject to a transformation based on certain rules-of-thumb. These are independent of any given implementation environment, but should subsequently be adaptable to any specific product. It should be close enough to the final design for timing and sizing exercises to be carried out. There are two versions of the first-cut Data Design: The implementation-independent design, followed by a first-cut design according to the supplied rules of the chosen environment. The former is often omitted, depending on the experience of the designer, or the requirements and complexity of the selected DBMS.

Ríomhairí, Ríomheolaíocht An t-aschur ó Staid 5, Dearadh Loighciúil. Cuimsíonn sé an tSamhail Loighciúil den Sreabhadh Sonraí atá de Dhíth, an phróiseáil loighciúil agus an Chatalóg Riachtanas. Is é an t-ionchur é don Dearadh Fisiciúil.
Computers, Computer Science The output from Stage 5, Logical Design. It embraces the Required System Logical Data Model, the logical processing, and the Requirements Catalogue. It serves as the input to Physical Design.
