 # The new EF Core JSON Columns
 
+In this article, we will see how to use the new JSON columns in EF Core 7.0.
+
 ## JSON Columns
 
 Most relational databases support columns that contain JSON documents. The JSON in these columns can be drilled into with queries. This allows, for example, filtering and sorting by the elements of the documents, as well as projection of elements out of the documents into results. JSON columns allow relational databases to take on some of the characteristics of document databases, creating a useful hybrid between the two.
 
 EF7 contains provider-agnostic support for JSON columns, with an implementation for SQL Server. This support allows mapping of aggregates built from .NET types to JSON documents. Normal LINQ queries can be used on the aggregates, and these will be translated to the appropriate query constructs needed to drill into the JSON. EF7 also supports updating and saving changes to the JSON documents.

+You can find more information about JSON columns in EF Core 7.0 in the [documentation](https://docs.microsoft.com/en-us/ef/core/what-is-new/ef-core-7.0/whatsnew#json-columns).
+
+### Mapping JSON Columns
+
+In EF Core, aggregate types are defined using `OwnsOne` and `OwnsMany`. 
+`OwnsOne` is used to map a single aggregate, and `OwnsMany` is used to map a collection of aggregates.
+
+`ToJson` is used to map a property to a JSON column. The property can be of any type that can be serialized to JSON.
+
+These aggregates can be mapped to JSON columns using the `ToJson` method. The following example shows how to map a JSON column to an aggregate type:
 
 ```csharp	
 public class ContactDetails

     public string Name { get; set; } = null!;
     public ContactDetails ContactDetails { get; set; } = null!;
 }
+```
+
+Above, we have defined an aggregate type `ContactDetails` that contains an `Address` and a `Phone` number. The aggregate type is configured in `OnModelCreating` using `OwnsOne` and `ToJson`. The `Address` property is mapped to a JSON column using `ToJson`, and the `Phone` property is mapped to a regular column. This requires just one call to ToJson() when configuring the aggregate type:

 public class MyDbContext : AbpDbContext<MyDbContext>

 ### Querying JSON Columns
 
+Queries into JSON columns work just the same as querying into any other aggregate type in EF Core. That is, just use LINQ! Here are some examples:
+
 ```csharp
 var persons = await (await GetDbSetAsync()).ToListAsync();
+```
+
 
+```csharp
 var contacts = await (await GetDbSetAsync()).Select(person => new
 {
     person,
     person.ContactDetails.Phone,
     Addresses = person.ContactDetails.Address
 }).ToListAsync();
