My search for the meaning of DCO was quite fruitless, so I decided to ask here. In my Java application, there are many classes like EmployeeDetailsDto, EmployeeDetailsDao, but recently I also came across EmployeeDetailsDco. Does anyone know what does the DCO stand for?

DTO — Data Transfer Object. DAO — Data Access Object.
It is an Data Transfer object which used to pass the properties from service layer to persistence layer. DAO: It is an Data Access object. it is also known as persistence layer.
I know DTO is a data transfer object and a BO is a business object.
In Spring Framework, Data Transfer Object (DTO) is an object that carries data between processes. When you're working with a remote interface, each call is expensive. As a result, you need to reduce the number of calls. The solution is to create a Data Transfer Object that can hold all the data for the call.
DTO = Data Transfer Object
DAO = Data Access Object
DCO = Dynamically Configurable Object?
From the article
an object whose implementation can change incrementally after it is running
