Use the substring() method in C# to find all substrings in a string.Let’s say our string is −XyzLoop through the length of the string and use the Substring function from the beginning to the end of the string −for (int start = 0; start
To count uppercase characters in a string, check the following condition −myStr[i]>='A' && myStr[i]='a' && myStr[i]
Firstly, create a new linked list −LinkedList myList = new LinkedList();Now add some elements in the linked list −// Add 6 elements in the linked list myList.AddLast("P"); myList.AddLast("Q"); myList.AddLast("R"); myList.AddLast("S"); myList.AddLast("T"); myList.AddLast("U");Let’s now find a node and add a new node after that −LinkedListNode node = myList.Find("R"); myList.AddAfter(node, "ADDED");ExampleYou can try to run the following code to find a node in the linked list.Live Demousing System; using System.Collections.Generic; class Program { static void Main() { LinkedList myList = new LinkedList(); // Add 6 elements in the linked list myList.AddLast("P"); ...

Data WarehousingData warehousing is a collection of tools and techniques using which more knowledge can be driven out from a large amount of data. This helps with the decision-making process and improving information resources. Data warehouse is basically a database of unique data structures that allows relatively quick and easy performance of complex queries over a large amount of data. It is created from multiple heterogeneous sources.Characteristics of Data WarehousingIntegratedTime variant Non-volatileThe purpose of Data warehouse is to support the decision making process. It makes information easily accessible as we can generate reports from the data warehouse. It usually contains historical data ... Read More
In object based data models, the focus is on how data is represented. The data is divided into multiple entities each of which have some defining characteristics. Moreover, these data entities are connected with each other through some relationships.So, in object based data models the entities are based on real world models, and how the data is in real life. There is not as much concern over what the data is as compared to how it is visualised and connected.Some examples of object based data models areEntity Relationship Data ModelObject Oriented Data ModelSemantic Data ModelFunctional Data ModelOut of these models, ...

The detailed comparison on the E- R model and Object Oriented Model is given as follows −E-R ModelER model is used to represent real life scenarios as entities. The properties of these entities are their attributes in the ER diagram and their connections are shown in the form of relationships. An ER model is generally considered as a top down approach in data designing.An example of ER model is −Advantages of E - R modelThe data requirements are easily understandable using an E - R model as it utilises clear diagrams.The E-R model can be easily converted into a relational database.The ...
