A lot of final students and freshers are usually in this dilema about Java and Asp.NET. Lets take it this way. In a software company if there are 100 employees, there would be 80 developers. So scope for development is huge. Now coming about choosing. Choose both. First go with Core Java programming and then go for .NET. You yourself will have fair idea after learning the core of both. Good Luck.

ExecuteNonQuery

ExecuteNonQuery method will return number of rows effected with INSERT, DELETE or UPDATE operations. This ExecuteNonQuery method will be used only for insert, update and delete, Create, and SET statements. 

 

ExecuteReader

Execute Reader will be used to return the set of rows, on execution of SQL Query or Stored procedure using command object. This one is forward only retrieval of records and it is used to read the table values from first to last. MOSTLY HELPFUL WHEN SEARCHNG FOR EXISTANCE OF PARTICULAR DATABASE RECORDS.since its only for searching and retrieval of records here as well INSERT, DELETE or UPDATE queries for its operations tobe performed is not applicable.

 

Execute Scalar

Execute Scalar will return single row single column value i.e. single value, on execution of SQL Query or Stored procedure using command object. It’s very fast to retrieve single values from database. as comapred to executeNonquery its not depended on INSERT, DELETE or UPDATE queries for its operations tobe performed.

What to choose between WCF or WEB API..?

  1. Choose WCF when you want to create a service that should support special scenarios such as one way messaging, message queues, duplex communication etc. while we need to choose web API. When you want to create a resource-oriented service over HTTP that can use the full features of HTTP (like URIs, request/response headers, caching, versioning, various content formats)

  2. Choose WCF whenever you want to create a service that can use fast transport channels when available, such as TCP, Named Pipes, or maybe even UDP (in WCF 4.5), and you also want to support HTTP when all other transport channels are unavailable. While we need to choose Web API when you want to expose your service to a broad range of clients including browsers,  iPhone, mobiles and tablets.

The benefits of using stored procedures in SQL Server rather than application code stored locally on client computers include.
 
                
1. They allow faster execution:
overall request-response traffic from client-server communication is much more optimised.
 
2. They can reduce network traffic.
What overall traffic for server responses return for the client request is reduced due to the mechanism of stored procedures. If less traffic the application runs much faster.
 
3. They can be used as a security mechanism.
By means of stored procedures, important database features like table name and its column names field remain unopen in the server side coding in ado.net .hence acts like a security mechanism. Hackers even if they invade into the code they cannot come across the database features. Database features are protected.

.1. TYPE SAFETY FEATURES.

2. OBJECT ORIENRED FEATURES.

3. Lamda Function

4. BRING GENERICS.

 

1. Type safety means an object when defined has its ability to understand of its own type and maintain it in future operations.object can be a string, integer, boolean, float, double etc.

2. Objected oriented means delegates can support the object-oriented features like inheritance polymorphism virtual functions. etc

3. Lamba function means delegate can create its own anonymously function types. that can handle its own kind of operations there is no need to specify a name in particular for that function.

4. Generics means giving higher valued definition to the delegate classes in terms of object creation.
