API (Application Programming Interface)

Definition 
1.A set of routines by which an application program can call specific programs or services of a computer operating system (OS) or network operating system (NOS).
2.A set of routines by which an application program allows another application program to work directly with it.
          
(Application Programming Interface) A language and message format used by an application program to communicate with the operating system or some other control program such as a database management system (DBMS) or communications protocol. APIs are implemented by writing function calls in the program, which provide the linkage to the required subroutine for execution. Thus, an API implies that a driver or program module is available in the computer to perform the operation or that software must be linked into the existing program to perform the tasks. Plenty of API Programming Is Done Understanding an API is a major part of what a programmer does. Except for writing the business logic that performs the actual data processing, all the rest of the programming is writing the code to communicate with the functions in the operating system and other system software. The APIs for operating systems can be daunting, especially the calls to the user interface routines to display contents on the screen. There are more than a thousand API calls in a full-blown operating system such as Windows, Mac or Unix.

    The very use of API is very popular today because in this case we can draw from other sources. However, when I use native applications, I know that they work directly in cloud computing. That is why I am of the opinion that if we want to have good IT solutions then just contact us via https://grapeup.com/contact/ and we will certainly get the answer to our question.

Hi friends ! Today I am discussing about simple but very important scenario. When we create any application then during creation of application we have face many scenarios like 1.Taking information from user and storing these information inside database : Generally such type of Operation is performed by user using form application 2.Taking Data from Database and Displaying on Page : We can perform such type of Operation in various ways like using JSP,JSTL tags or you can perform such operations using JQUERY also. 3.Taking Data from Database and download it in Excel or CSV format : In this we want our data from database and store it inside Excel or text files for further use. And we have chosen third scenario from discussion for performing this Operation we have to need three files exportCsv.html  :- this contains a button for clicking and performing exporting data from database Operation ExportData.java  :- It is a servlet class which defines connectivity from databas

Secure Database Connectivity in node.js with mysql

Hi Everyone! Yesterday my friend Andrea from Italy asked me a question about secure Database connectivity in node.js with mysql i.e. he wants to a secure database connection in node.js for some secure keys like username,password,database name that we use during database connectivity.His problem is obviously right from security point of view as we know that JavaScript is client side scripting knowledge so it is compiled on client side so after inspecting page some one can be able to view these secure keys which I discussed previously. I surf internet and found there are various ways to solve this problem I am not discussing all of them here but also I discussing here two of them and after this discussion I think Andrea and other reader who are facing with same problem can be able to resolve their problem. I choose two ways to solve this problem. Connection code in app.js file Create a Json file Connection code in app.js file : Javascript is client side language and code i

Java Web Scraping

Today I introduced you from a new word i.e. Web scraping this word is used for extracting data from a website for some purpose. In this technique we extract large amount data from website and store inside our local file or we can also store these data inside our database for personal use .Now this technique is widely used all around the world because in the age of Information data is every thing.As much amount of you have as much power you have.Most of programming languages contains package for Web Scraping such in python we used BeautifulSoup.  BeautifulSoup is a fantastic tool of python for web Scraping. I don't know much about python and I am good in java so, here I am discussing here  how we can scarp data from website using concepts of Java? Now, we are presenting a little package for Java web Scarping. Jsoup is an open source Java HTML parser. Jsoup is an open source HTML parser which is used for scraping in Java.It uses DOM,CSS and Jquery-like methods for extra
