what are different types of view?

Posted By :BangaruBabuPureti     Posted Date :June 23, 2010    Points :10   Category :Sql Server 
Simple view - created on single table
Complex view- created on more than one table

All types in C# implicitly derive from.........

System.Object Class. System.Object is the parent class of all .NET classes (More...)

What is a view?

If we have several tables in a db and we want to view only specific columns from specific tables we can go for views. It would also suffice the needs of security some times allowing specfic users to see only specific columns based on the permission that we can configure on the view. Views also reduce the effort that is required for writing queries to access specific columns every time. (More...)

What are the types of indexes available with SQL Server?

There are basically two types of indexes that we use with the SQL Server. Clustered and the Non-Clustered. (More...)

What is a view? How it is related to data independence?

A view may be thought of as a virtual table, that is, a table that does not really exist in its own right but is instead derived from one or more underlying base table. In other words, there is no stored file that direct represents the view instead a definition of view is stored in data dictionary.

Growth and restructuring of base tables is not reflected in views. Thus the view can insulate users from the effects of restructuring and growth in the database. Hence accounts for logical data independence. (More...)

What is VDL (View Definition Language)?

It specifies user views and their mappings to the conceptual schema. (More...)

Different Types of Remote Objects?

The remoting infrastructure allows you to create two distinct types of remote objects.

1.Client-activated objects - A client-activated object is a server-side object whose creation and destruction is controlled by the client application. An instance of the remote object is created when the client calls the new operator on the server object. This instance lives as long as the client needs it, and lives across one to many method calls. The object will be subject to garbage collection once it''s determined that no other clients need it.

2.Server-activated objects - A server-activated object''s lifetime is managed by the remote server, not the client that instantiates the object. This differs from the client-activated object, where the client governs when the object will be marked for finalization. It is important to understand that the server-activated objects are not created when a client calls New or Activator.GetObject. They are rather created when the client actually invokes a method on the proxy. There are two types of server activated objects. They are:

I. Single call . Single-call objects handle one, and only one, request coming from a client. When the client calls a method on a single call object, the object constructs itself, performs whatever action the method calls for, and the object is then subject to garbage collection. No state is held between calls, and each call (no matter what client it came from) is called on a new object instance.

II.Singleton - The difference in a singleton and single call lies in lifetime management. While single-call objects are stateless in nature, singletons are stateful objects, meaning that they can be used to retain state across multiple method calls. A singleton object instance serves multiple clients, allowing those clients to share data among themselves. (More...)

what are value types and reference types?

Value type - bool, byte, chat, decimal, double, enum , float, int, long, sbyte, short, strut, uint, ulong, ushort
Value types are stored in the Stack
Reference type - class, delegate, interface, object, string
Reference types are stored in the Heap (More...)

What are the types of threading models?

. Single Threading: This is the simplest and most common threading
model where a single thread corresponds to your entire application's
Apartment Threading (STA): This allows multiple threads to exist in a
single application. In single threading apartment (STA), each thread
is isolated in it's own apartment. The process may contain multiple
threads (apartments) however when an object is created in a
thread (i.e. apartment) it stays within that
apartment. If any communication needs to occur between different
threads (i.e. different apartments) then we must marshal the first
thread object to the second thread.
Free Threading: The most complex threading model. Unlike STA,
threads are not confined to their own apartments. Multiple treads can
make calls to the same methods and same components at the
same time. (More...)

Session state vs View state

In some cases, using view state is not feasible. The alternative for view state is session state. Session state is employed under the following situations:
. Large amounts of data - View state tends to increase the size of both the HTML page sent to the browser and the size of form posted back. Hence session state is used.
. Secure data - Though the view state data is encoded and may be encrypted, it is better and secure if no sensitive data is sent to the client. Thus, session state is a more secure option.
. Problems in serializing of objects into view state - View state is efficient for a small set of data. Other types like DataSet are slower and can generate a very large view state (More...)

How many types of tables are present in SQL SERVER?

There are 2 types of temporary tables, local and global in sql server.

Local temporary tables are created using a single pound (#) sign and are visible to a single connection and automatically dropped when that connection ends.

Global temporary tables are created using a double pound (##) sign and are visible across multiple connections and users and are automatically dropped when all SQL sessions stop referencing the global temporary table. (More...)

What are the different types of Assembly?

There are two types of assembly Private and Public assembly.

A private assembly is normally used by a single application, and is stored in the application's directory, or a sub-directory beneath. A shared assembly is normally stored in the global assembly cache, which is a repository of assemblies maintained by the .NET runtime. Shared assemblies are usually libraries of code which many applications will find useful, e.g. Crystal report classes which will be used by all application for Reports. (More...)

What are different types of JIT?

JIT compiler is a part of the runtime execution environment.
In Microsoft .NET there are three types of JIT compilers:
.Pre-JIT: - Pre-JIT compiles complete source code into native code in a single compilation cycle. This is done at the time of deployment of the application.
.Econo-JIT: - Econo-JIT compiles only those methods that are called at runtime. However, these compiled methods are removed when they are not required.
.Normal-JIT :- Normal-JIT compiles only those methods that are called at runtime. These methods are compiled the first time they are called, and then they are stored in cache. When the same methods are called again, the compiled code from cache is used for execution. (More...)

What are Value types and Reference types?

Value types directly contain their data which are either allocated on the stack or allocated in-line in a structure. Reference types store a reference to the value's memory address, and are allocated on the heap. Reference types can be self-describing types, pointer types, or interface types. Variables that are value types each have their own copy of the data, and therefore operations on one variable do not affect other variables. Variables that are reference types can refer to the same object; therefore, operations on one variable can affect the same object referred to by another variable. All types derive from the System.Object base type. (More...)
