Data mining is a process of extracting useful information and data patterns from data, whereas a data warehouse is a database management system developed to support the management functions. Read this article to learn more about Data Mining and Data Warehousing and how they are different from each other. What is Data Mining? Data Mining is a process used to determine data patterns and extract useful information from data. It can be understood as a general method to extract useful data from a set of data. In the data mining process, data is analyzed repeatedly to find patterns. Data mining ... Read More
What is Padding in Android? Padding is a space which is present between the content which we have to display and the border of that content. Padding is used to create the extra space within the content. We can add padding for a widget from any of the specific sides. We can add padding either from left, right, top or bottom depending upon the requirement. In this article we will take a look on How to use padding attributes for different widgets within our android application. Syntax android:padding="Size in dp" Explanation − Above syntax for padding is used ... Read More
Data mining and data science are the two most important concepts in information technology. Data mining is a process of determining useful information, trends, and patterns from large databases, so that these parameters can be used to solve several business problems. On the other hand, data science is the process of obtaining important insights from the unstructured and structured data by using different analysis tools. Basically, data science is one of the modern emerging fields of computer science and information technology for the study of largescale data analysis. Read this article to learn more about Data Mining and Data Science ... Read More
Data Lake and Data Warehouse both are used for storing big data. A Data Lake is a very big storage repository which is used to store raw unstructured data, machine to machine, logs flowing through in real-time. The purpose of the stored data is not defined in a data lake. They are stored for future analysis of the data. A data warehouse is a repository for structured, filtered data that has already been processed for a specific purpose. A Data warehouse collects the data from multiple sources and transforms the data using ETL process, then loads it to the Data ... Read More
Metadata is a form of Data, but both are not the same. Data and metadata are used for different purposes and have different specifications. Data is simply defined as a set of raw facts and figures, while metadata is one that provides relevant information about the data. Read this article to learn more about data and metadata and how they are different from each other. What is Data? Raw facts and figures obtained from an observation, measurement, etc. are called data. Data makes the basis of processing. For a user, raw data may not always be meaningful. Data is first ...

In Go programming language, a tree is a frequently used data structure that resembles an upside-down tree or an inverted tree with parent-child relationships between the nodes. In a tree, each node has a value and zero to many nodes as offspring. The root node is the node without a parent, while the leaves are the nodes without children. Trees can be employed for a variety of tasks, including data storage, sorting, and searching in hierarchical structures. We will use two methods to perform inorder tree traversal. Syntax func make ([] type, size, capacity) The make function in go ... Read More
In go we can use strings.Join to convert a arraylist into string. Here we will understand how we can use strings.Join to combine multiple texts from an array that are separated by commas and spaces also, strings. To create an array of strings, use the Split function on the string. Let’s see through the code and algorithm how its executed. Syntax func Join(s []string, sep string) string The join function is used to convert an array to string. This function is present in strings package. it takes two arguments first one is the array that we wish to convert ... Read More
In the Go programming language, a linkedlist is a data structure made up of a series of nodes, each of which has a value and a reference (pointer) to the node after it. Since items can be added to or removed from a list without rearranging the entire data set, linked lists offer a dynamic and adaptable approach to store data. Using structs and pointers, linked lists can be implemented in Go whereas array is a fixed-size group of identical elements that may be accessed by their respective indexes, which are integers with a zero-based basis. An array's size is ... Read More
We can use chmod function and syscall package in Golang to make a file read-only file. To convert a file into read-only files, the chmod function set the file’s right to 044. The os.Chmod function is then used to modify the file's mode. In syscall package of Golang we are going to use os.stat function to obtain information about the file. Method 1: Using chmod function This program employs the Chmod function to modify a file's permissions using the os package. Syntax os.Chmod In Go, this function belongs to the os package. The main goal of this function is ... Read More
In go programming language we can use os.create and ioutil.WriteFile to write into a file. In Go, the OS can be used to represent a file. os package file type that offers ways to open, read from, write to, and manipulate files. Method 1: Using os.Create function We make use of the os.Create in this program to start a new file or, if one already exists, to open it. The file is deferred while a string is written using the WriteString function. Close makes ensuring that when the application ends, the file is correctly closed. Syntax Os.Create In ... Read More
