It explains conceptual models as high-level abstractions that naturally represent real-world facts, properties, and relationships, independent of any specific database system and focused on application semantics, providing the entity-relationship model as an example. It then transitions to logical database models, which support access methods and specify data concepts, domains, relationships, and constraints using Data Definition Language (DDL), as well as manipulation of modeled concepts using Data Manipulation Language (DML). The document also illustrates database schemas, both logical and conceptual, using examples of how to define entities and their attributes, such as 'Matrícula' (Enrollment) with attributes like 'Nome' (Name) and 'AnoIngresso' (Year of Entry), and 'Código' (Code) with 'Nome' (Name). The text emphasizes that a logical schema is the result of specifying data for an application domain within a database model, providing a clear distinction between conceptual and logical modeling approaches in database design.",{"@graph":51,"@context":106},[52,68,89],{"@type":53,"itemListElement":54},"BreadcrumbList",[55,59,62,65],{"item":56,"name":57,"@type":58,"position":9},"https://docshare.wps.com","Home","ListItem",{"item":60,"name":10,"@type":58,"position":61},"https://docshare.wps.com/pt/template/",2,{"item":63,"name":35,"@type":58,"position":64},"https://docshare.wps.com/pt/template/geral/",3,{"item":66,"name":47,"@type":58,"position":67},"https://docshare.wps.com/pt/template/relational-model/190586/",4,{"url":66,"name":47,"@type":69,"image":70,"author":75,"headline":47,"publisher":78,"fileFormat":81,"inLanguage":45,"description":49,"dateModified":82,"datePublished":83,"encodingFormat":81,"isAccessibleForFree":84,"interactionStatistic":85},"DigitalDocument",{"url":71,"@type":72,"width":73,"height":74},"https://docshare.wps.com/thumbnails/relational-model/190586.png","ImageObject",442,249,{"name":76,"@type":77},"supergirl","Person",{"url":56,"name":79,"@type":80},"DocShare","Organization","application/pdf","2026-10-06","2026-09-03",true,{"@type":86,"interactionType":87,"userInteractionCount":64},"InteractionCounter",{"@type":88},"ViewAction",{"@type":90,"mainEntity":91},"FAQPage",[92,98,102],{"name":93,"@type":94,"acceptedAnswer":95},"What
