Data Exchange

Components of Data Exchange Systems

Data Exchange application

Digital methods of data exchange

Is an application where data can be moved from one application to another/between stake holders

Provides global access to data points

Enables both parties or receiving ends of the exchange a more efficient and intelligent way of service delivery

Data Consumer System

Data Provider System

Request Data

Object Structures

Data import and export

API Keys

Text-Based Formats

JSON

Data Structures

Objects

Array

Has minimal number of data values which are common to most programming language, enabling exchange across language gaps

Supported by many different programming languages

Data exchange protocol derived from JavaScript

XML

elements

Nested child attributes

Binary Based Format

CORBA(The Common Object Request Broker Architecture)

Google Protocol Buffers, Avro, Thrift

Transfer Protocols

File Transfer Protocol (FTP)

FTP over SSL (FTPS)

Hypertext Transfer Protocol (HTTP)

HTTP over SSL (HTTPS)

Network File System (NFS)

Unique identifier

when attached to a external client, the external client are allowed to directly interact and access the data

used to assist in tracking how the interface is being uitlized

Allows secure identification

Direct interaction with consumer

Generates a JSON data packet and formats it into groups that are transmitter over the internet to the dat consumer system

REST (Representational State Transfer)

Archictectural style which is for developing web services

Principles to make a RESTful API

Uniform Interface

Client-Server

Stateless

Cacheable

Layered System

REST can structure data in XML and JSON

Data Interface

RSS (Realy Simple Syndication)

the collection of web formats collated into a file that contain updated and shared information in a standardized way

API( Application Programming Interface)

Its acts as an intermediary communicates between the two systems by delivering the users response to the system and in the same the system's response or initial request to the user

API data is an open format, which publishes specific data

Provider Data exists in data server, API is intermediary between web client and data server/base
