Medium Global Query Filters Global Query Filters Soft Delete	Try practice test
In an Entity Framework Core project, you're working on an e-commerce application where products can be 'soft deleted'. A soft deleted product is not physically removed from the database, but is flagged as deleted and should not appear in normal query results. Assume that your Product model includes an IsDeleted boolean property. Your task is to implement a global query filter to exclude soft deleted products from all queries throughout the application. Which of the following is the correct way to implement this requirement in your DbContext derived class, ProductContext?
Medium Implicit and Explicit Loading Loading Strategies Relationships	Try practice test
In an Entity Framework Core project, you have two related entities, Product and Category. Each Product entity has a navigation property Category that represents the Category entity associated with the product. You have the following code that retrieves a product: The Product and Category entities are defined as follows: You call the GetProduct method and then access the Category.Name property of the returned Product entity. What will happen? A: The Category.Name property will have the name of the category associated with the product.

Reason #5

Designed for elimination, not selection

The most important thing while implementing the pre-employment Entity Framework Online Test in your hiring process is that it is an elimination tool, not a selection tool. In other words: you want to use the test to eliminate the candidates who do poorly on the test, not to select the candidates who come out at the top. While they are super valuable, pre-employment tests do not paint the entire picture of a candidate’s abilities, knowledge, and motivations. Multiple easy questions are more predictive of a candidate's ability than fewer hard questions. Harder questions are often "trick" based questions, which do not provide any meaningful signal about the candidate's skillset.

Science behind Adaface tests

Reason #6

1 click candidate invites

Entity Framework Designer
Entity Framework Designer er et visuelt verktøy som brukes til å designe enhetsmodeller , Kartlegging av databaseobjekter til enhetsklasser. Å forstå enhetsrammeutdesigneren gjør det mulig Enhetsramme for å kartlegge databaseobjekter til enhetsobjekter. Å vurdere kandidatenes kunnskap om ORM sikrer at de kan jobbe effektivt med enhetsrammen og forstå de underliggende prinsippene for objekt-relasjonell kartlegging.
Databasekobling
Databasekoblingsevner involverer å etablere og vedlikeholde Tilkoblinger til databaser for å utføre dataoperasjoner. Evaluering av databasekoblingsevner hjelper til med å identifisere kandidater som effektivt kan etablere databaseforbindelser, håndtere tilkoblingssamling og effektivt administrere databasetilgang i sammenheng med enhetsrammen.
LINQ
LINQ (språk integrert Spørring) er et kraftig trekk ved enhetsrammen som muliggjør spørring og manipulering av data på en typesikker måte. Å vurdere kandidatenes kunnskap om LINQ sikrer at de kan utnytte LINQ-uttrykk for å effektivt spørre data og utføre komplekse datamanipulasjoner.
Database First Approach
Database-First-tilnærmingen i enhetsrammen involverer generere enhetsmodellen fra et eksisterende databaseskjema. Vurdering av kunnskap om database-første tilnærming sikrer at kandidater kan jobbe med eksisterende databaser og generere enhetsmodeller nøyaktig og effektivt.
spørringsoptimalisering
spørringsoptimaliseringsevner involverer forståelse og implementering av teknikker for å forbedre Ytelsen til databasespørsmål i enhetsrammen. Kandidater med sterke spørringsoptimaliseringsevner kan skrive effektive spørsmål, optimalisere databasetilgang og forbedre den generelle applikasjonsytelsen.
Datatilgangslag
Datatilgangslaget er komponenten i en applikasjon som er ansvarlig for hente og manipulere data fra databasen. Vurdering av kunnskap om datatilgangslaget i sammenheng med enhetsrammen sikrer at kandidater kan designe og implementere effektive datatilgangskomponenter som samhandler sømløst med rammen.
Databasedesign
Databasedesign Ferdigheter omfatter muligheten til å analysere krav og designe effektive og skalerbare databaseskjemaer. Evaluering av kandidaters kunnskap om databasedesign sikrer at de kan designe databaseskjemaer som samsvarer med beste praksis, optimaliserer datalagring og letter effektiv datainnhenting og manipulering.
Resultatinnstilling

Entity Framework Hiring Test Vanlige spørsmål

Hva er enhetsrammevurderingstest?

Entity Framework Assessment Test er et testverktøy før ansettelse som brukes av arbeidsgivere for å vurdere en kandidats evne til å jobbe med enhetsrammen. Det er en .NET Framework-komponent som gjør det mulig for utviklere å jobbe med data på en objektorientert måte.

Vurderingstesten fokuserer på spørsmål rundt enhetsrammearkitektur, Entity Data Model (EDM), Entity SQL Language, Object Services API og andre grunnleggende emner å teste for ferdigheter på jobben.

Kan jeg kombinere flere ferdigheter til en tilpasset vurdering?

Ja absolutt. Tilpassede vurderinger er satt opp basert på stillingsbeskrivelsen din, og vil inneholde spørsmål om alle må-ha ferdigheter du spesifiserer.

Har du noen anti-juksende eller proktoreringsfunksjoner på plass?

Vi har følgende anti-juksede funksjoner på plass:

Ikke-googlable spørsmål
IP Proctoring
Nettproctoring
Webcam Proctoring
Deteksjon av plagiering
Sikker nettleser

Les mer om Proctoring -funksjonene.

Hvordan tolker jeg testresultater?

Den viktigste tingen å huske på er at en vurdering er et eliminasjonsverktøy, ikke et seleksjonsverktøy. En ferdighetsvurdering er optimalisert for å hjelpe deg med å eliminere kandidater som ikke er teknisk kvalifisert for rollen, det er ikke optimalisert for å hjelpe deg med å finne den beste kandidaten for rollen. Så den ideelle måten å bruke en vurdering på er å bestemme en terskelpoeng (vanligvis 55%, vi hjelper deg med å benchmark) og invitere alle kandidater som scorer over terskelen for de neste rundene med intervjuet.

Hvilken opplevelsesnivå kan jeg bruke denne testen til?

Hver ADAFACE -vurdering er tilpasset din stillingsbeskrivelse/ ideell kandidatperson (våre fageksperter vil velge de riktige spørsmålene for din vurdering fra vårt bibliotek med 10000+ spørsmål). Denne vurderingen kan tilpasses for ethvert opplevelsesnivå.

Får hver kandidat de samme spørsmålene?

Ja, det gjør det mye lettere for deg å sammenligne kandidater. Alternativer for MCQ -spørsmål og rekkefølgen på spørsmål er randomisert. Vi har anti-juksing/proctoring funksjoner på plass. I vår bedriftsplan har vi også muligheten til å lage flere versjoner av den samme vurderingen med spørsmål med lignende vanskelighetsnivåer.
