What is type system unification?

The goal of type system unification is to bridge the gap between value types and reference types that exists in most languages. For example, a Stack class can provide Push and Pop methods that take and return object values.

public class Stack
public object Pop() {...}
public void Push(object o) {...}
Because C# has a unified type system, the Stack class can be used with elements of any type, including value types like int. (More...)

What is the common type system (CTS)?

The common type system is a rich type system, built into the Common Language Runtime, that supports the types and operations found in most programming languages. The common type system supports the complete implementation of a wide range of programming languages. (More...)

What is a Database system?

The database and DBMS software together is called as Database system. (More...)

Disadvantage in File Processing System?

1.Data redundancy & inconsistency.
2.Difficult in accessing data.
3.Data isolation.
4.Data integrity.
5.Concurrent access is not possible.
6.Security Problems. (More...)

What is System R? What are its two major subsystems?

System R was designed and developed over a period of 1974-79 at IBM San Jose Research Center. It is a prototype and its purpose was to demonstrate that it is possible to build a Relational System that can be used in a real life environment to solve real life problems, with performance at least comparable to that of existing system.
Its two subsystems are
1.Research Storage
2.System Relational Data System. (More...)

How is the data structure of System R different from the relational structure?

Unlike Relational systems in System R
1.Domains are not supported
2.Enforcement of candidate key uniqueness is optional
3.Enforcement of entity integrity is optional
4.Referential integrity is not enforced (More...)

where is global assembly cache location in system?

The .NET Framework ships with a Windows shell extension for viewing the assembly cache. Navigating to % windir%\assembly with the Windows Explorer activates the viewer. (More...)

What is the Transport Protocol you use to call a Web Service ?

SOAP (Simple Object Access Protocol) is the preferred protocol. (More...)

What is SQL Server Service broker?

Service Broker is a unique feature in Microsoft SQL Server 2005 which is used to by internal or external processes to send and receive guaranteed, asynchronous messages by using extensions to Transact-SQL Data Manipulation Language (DML).

It's a platform for building a new class of loosely coupled services for database applications. Service Broker not only brings asynchronous, queued messaging to database applications but significantly expands the state of the art for reliable messaging.

The key components of SQL Server Service broker are
.Queue stores the messages for a particular service.
.Dialog is a conversation between two services.
.Conversation group is a group of related conversations. Every conversation belongs to exactly one conversation group.
.Activation specifies a stored procedure that will handle messages destined for a particular service. (More...)

What are the essential components of SQL Server Service broker?

Service Broker uses queues to provide loose coupling between the message sender and the message receiver. The sender can put a message in a queue and then continue on with the application, relying on Service Broker to ensure that the message reaches its destination. Queues permit a lot of scheduling flexibility.

Dialogs are bidirectional streams of messages between two endpoints. All messages in a dialog are ordered, and dialog messages are always delivered in the order they are sent. The order is maintained across transactions, across input threads, across output threads, and across crashes and restarts.

Conversation Groups
It's a way of grouping all the dialogs that are used for a particular task. All the dialogs associated with processing a particular order would be grouped into a single conversation group. The conversation group is implemented as a conversation group identifier, which is included with all messages in all dialogs contained in the conversation group. When a message is received from any of the dialogs in a conversation group, the conversation group is locked with a lock that is held by the receiving transaction. For the duration of the transaction, only the thread that holds the lock can receive messages from any of the dialogs in the conversation group. This makes our order entry application much easier to write because even though we use many threads for scalability, any particular order is only processed on one thread at a time. This means we don't have to make our application resilient to problems that are caused by the simultaneous processing of a single order on multiple threads.

You use the activation feature of Service Broker to specify a stored procedure that will handle messages destined for a particular service. When messages arrive for a service, Service Broker checks whether there is a stored procedure running that can process the messages. If there isn't a running message-processing stored procedure, Service Broker starts one. The stored procedure then processes messages until the queue is empty, after which it terminates. Moreover, if Service Broker determines that messages are arriving faster than the stored procedure can process them, it starts additional instances of the stored procedure until enough are running to keep up with the incoming messages (or until the configured maximum number is reached). This ensures that the right number of resources for processing incoming messages are always available. (More...)
