Need help to create PDF using Acrobat objects and secure the file by setting password and encryption programmatically - c# please respond ASAP. Product Name is an attribute of the product member. Because the Product ID in the dimension table matches the Product ID in the fact table, it is called the key attribute. Because there is one Product Name for each Product ID, the name is simply what you display instead of the number, so it is still considered to be part of the key attribute. In the data warehouse, the key attribute in a dimension table must contain a unique value for each member of the dimension. In relational database terms, this key attribute is called a primary key column. The primary key column of each dimension table corresponds to one of the key columns in any related fact tables. Each key value that appears once in the dimension table will appear multiple times in the fact table. For example, the Product ID 347, for Mountain100, should appear in only one dimension table row, but it will appear in many fact table rows. This is called a one-to-many relationship. In the fact table, a key column (which is on the many side of the one-to-many relationship) is called a foreign key column. The relational database uses the matching values from the primary key column (in the dimension table) and the foreign key column (in the fact table) to join a dimension table to a fact table. open password protected pdf using c# Encrypt PDF Document in C# , VB.NET - E-iceblue

Other data access objects in the model move the data between the database and the datasets. XML support is built into the model, as DataSet objects can easily be serialized into and deserialized from XML. No doubt bookstores will soon have shelves of thick books about ADO.NET. In this section, you ll see a small selection of the many options available in ADO.NET. For more comprehensive coverage, try Microsoft ADO.NET Step by Step (Microsoft Press, 2002). In this second exercise, you ll fill a DataGrid control with data stored in a DataSet instance. In the first portion of the exercise, you ll define the structure of the DataSet at run time, creating what s known as an untyped DataSet. In the second portion, you ll let the Microsoft Visual Studio development environment create the DataSet structure at design time, using what s known as a typed DataSet.
