Building a web API with the n-layer architecture

Abstract

In processes that involve digital technologies and automation, companies need to innovate to obtain efficient computer systems with better performance; Accordingly, in the company BCD travel, the project "BUILDING A WEB API WITH N LAYERS ARCHITECTURE" was developed, due to the fact that the Data Service (DS) data access tool was discontinued. The objective of the project was the creation of an Application Programming Interface (API), capable of maintaining the communication and transmission of information to each of the processes and systems that are executed in this company. The construction of the Web API (Data Service Tool with Application Programming Interface) called DSA was based on an N-layer architecture, using Active Server Page Technology (ASP.Net) and the C Sharp programming language, applying the Object Relational Mapping (ORM) programming model belonging to the ADO.NET Entity Framework in order to map the structures of Relational Databases and transform the tables to simplify the work of developers. The benefits that the DSA has had is that it is a multitasking tool and can be used in desktop applications, on Web sites or in mobile applications, data query times are faster and queries can be made in parallel without affecting performance From the API, one more benefit of the DSA is that any developer can maintain it, adding or removing queries to the Database tables according to the processing needs they have.
