+### Relationship types:
+
+- One to one
+  - A Table record in first table is related to only one record of second table.
+  - Example: Country has a capital city
+- One to many
+  - A Table record in first table is related to more than one record of second table. But second table record maps to only one entry of first table
+  - NocoDB refers to this category of relationship as **has many**
+  - For every **has many** relation defined, NocoDB augments **belongs to** relationship column in the other table automatically
+  - Example: Country **has many** Cities. (other way mapping > City **belongs to** Country )
+- Many to many
+  - A Table record in first table is related to more than one record of second table; second table record can also map to more than on record of first table.
+  - NocoDB refers to this category of relationship as **many to many**
+  - For every **many to many** relation defined between tables, NocoDB augments **many to many** relationship column in the other table automatically
+  - Example: Film **has many** Actors. Actor **has many** Films (works on many films)
+
+Further details of relationship types can be found [here](https://afteracademy.com/blog/what-are-the-different-types-of-relationships-in-dbms)
+
+From Release v0.110.0, table records can be connected through relationships using the **Links** column type. 
+It is important to note that, earlier supported column type **LinkToAnotherRecord** for creating relations is considered deprecated. While the old datatype is still supported for backward compatibility, it is no longer possible to create new fields of that type.
+
+The main distinction between these two column types lies in how the contents are displayed within the cell when links are established between two tables. With the **LinkToAnotherRecord** column type, the cell displays the **Primary value** of the related records. On the other hand, the **Links** column type only shows the **count** of related records.
+The decision to switch over to new column type was made to ensure better performance and scalability of the application, more so when the records & the number of records in the related table is large.
+  
+Child list to display the related records can be accessed by clicking on the link count displayed on the cell. 
+Except for the column type, the following procedures remain same as before 
+- create, update & delete a relationship column, 
+- link & unlink a record, 
+- create a lookup and rollup columns 
+
+Workflow details are captured below.
