Raster data is a set of horizontal lines composed of individual pixels, used to form an image on a CRT or other screen.Raster data makes use of matrix of square areas to define where features are located. These squares are typically of uniform size, and their size determines the detail that can be maintained in the dataset.Raster data represent square areas, they describe interiors rather than boundaries. Vector data use X and Y coordinates to define the locations of points, lines, and areas (polygons) that correspond to map features, vector data tend to define centers and edges of features.They are excellent for capturing and storing spatial details

Code
#pragma pack(1)

A database is an organized collection of information.  It is structured so you can jump to the information by using a key, and find related infromation by navigating a path.  A sequential (flat)  file is not considered a database. 

A relational database contains one-to-many relationships.

A networked database contains one-to-many and many-to-many relationships.

There will be a lot of changes in fact. First of all, all the variables the function was suing needs to be pushed into the stack. (we need all these variables when we return from the other function). The Program counter will be pushed to stack too... (When the "return" of second function occurs we should know where to 'return' to)These are the basics which are bound to happen when a function calls another.

What is the difference between Decode and Case with examples?

Manohar

• Oct 4th, 2017

Decode is a function I used it way back in Oracle 6 and 7. Slower than Case.
Case is statement I think it is introduced in 9i, you can use Case instead of Decode, I feel Case is faster when compared to Decode as it jumps to end when condition is met and simpler to understand

VAIBHAV GUPTA

• Apr 9th, 2016

Decode is used in a select statement where as case is a independent statement which occur in where clause.
decode is used for static value but we can use the case for range and can enable complex business logic.
Case is faster than decode.
