Why data contract

The benefit of a data contract is not only transparency but also cross-team collaboration. If that solution is a more ideal method of ingesting data say perhaps a Kafka Topic you can subscribe to , then even better! Taking the earlier example of ingesting order data, perhaps the source system team built an API specifically for use by the data engineering team. The API was built to handle large volumes of data, extracted either in full or incrementally.

Because the source system team built it specifically for extractions, they are also aware of what the data engineering team is doing and will thus be more likely to stay in touch as issues arise or changes to the system are planned. So in short, yes! For example, porting data to a new version might require multiple transactions when the block gas limit on Ethereum prevents an overly complex data migration transaction.

The standard practice of separating data from business logic can be applied to solve this problem. We can maintain the data and business logic in two separate smart contracts.

As of. Thx for clarifying that point! I will dig it a bit further then! Merci beaucoup! Show 5 more comments. Pradeep atkari Pradeep atkari 1 1 gold badge 6 6 silver badges 14 14 bronze badges. That's all true and fine, but it doesn't really answer the OP's question as to why the data contract serializer also works without any [DataContract] and [DataMember] attributes on your classes A data contract can be defined as follows: It describes the external format of data passed to and from service operations It defines the structure and types of data exchanged in service messages It maps a CLR type to an XML Schema It defines how data types are serialized and deserialized.

Through serialization, you convert an object into a sequence of bytes that can be transmitted over a network. Through deserialization, you reassemble an object from a sequence of bytes that you receive from a calling application. It is a versioning system that allows you to manage changes to structured data We need to include System. Kamran Kamran 6 6 silver badges 9 9 bronze badges.

For a data contract to be valid, it must be possible to serialize all of its data members. Generic types are handled in exactly the same way as non-generic types.

There are no special requirements for generic parameters. For example, consider the following type. This type is serializable whether the type used for the generic type parameter T is serializable or not. Because it must be possible to serialize all data members, the following type is serializable only if the generic type parameter is also serializable, as shown in the following code.
