Lind.DDD.Repositories.Mongo Layer Introduction

Back to Catalog

It's been happening before.

The older uncle had previously talked about the warehousing of MongoDB, And after the uncle developed the LIND.DDD, decided to move this thing to the storage layer of this framework, which is also the trend, after all, MongoDB is the most like relational database NoSQL, its use of the scene is other nosql can not, this is beyond doubt!

Below is the uncle's summary of the MongoDB article directory, selected from the Uncle MongoDB series >

Storage module in LIND.DDD, MongoDB has a place

Uncle's MONGODB storage structure

When designing MongoDB queries and updates, the uncle used the recursive

  /// <summary>        ///Builders updated as needed///Recursive build Update operation string/// </summary>        /// <param name= "FieldList" ></param>        /// <param name= "property" ></param>        /// <param name= "PropertyValue" ></param>        /// <param name= "item" ></param>        /// <param name= "Fathervalue" ></param>        /// <param name= "father" ></param>        Private voidgeneraterecursionexpress (List<UpdateDefinition<TEntity>>FieldList, PropertyInfo property,ObjectPropertyValue, TEntity item,ObjectFathervalue,stringfather) {            //Complex Types            if(property.
