Jak przypisać własności modelu poszczególnym własnościom bazy w EF?

public class PersonModel
    {
        [Key]
        [JsonProperty("ix")]
        [XmlElement("ix")]
        public int Index { get; set; }

        [XmlElement("content")]
        public ContentModel Content { get; set; }
    }

    [XmlRoot(ElementName = "content")]
    public class ContentModel
    {
        [JsonProperty("name")]
        [XmlElement("name")]
        public string Name { get; set; }
        [JsonProperty("visits")]
        [XmlElement("visits", IsNullable = true)]
        public int? Visits { get; set; }
        public bool ShouldSerializeVisits() { return Visits != null; }
        [JsonProperty("date")]
        public DateTime Date { get; set; }

        [XmlElement("date")]
        public string dateRequested
        {
            get { return Date.ToString("yyyy-MM-dd"); }
            set { Date = DateTime.ParseExact(value, "yyyy-MM-dd", System.Globalization.CultureInfo.InvariantCulture); }
        }
    }

<?xml version="1.0" encoding="utf-8"?>
<PersonXmlModel xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns:xsd="http://www.w3.org/2001/XMLSchema">

    <name>Jadon</name>
    <date>2009-12-21</date>
  </content>
</PersonXmlModel>

public void AddItem(PersonModel request)
        {
            PersonModel dataItem = new PersonModel
            {
                Index = request.Index,
                Content = new ContentModel
                {
                    Name = request.Content.Name,
                    Visits = request.Content.Visits,
                    Date = request.Content.Date
                }
            };
            _context.Requests.Add(dataItem);
            _context.SaveChanges();
        }

Index
Name
Visits
Date

public class PersonModelDatabase
    {
        public int Index { get; set; }
        public string Name { get; set; }
        public int? Visits { get; set; }
        public DateTime Date { get; set; }
    }
