What is Database Architecture

Database  Architecture 



Database store a lot of critical information to access data quickly and security we need to select the correct architecture for efficient data for management client for the machine is the database architecture client .Database management system architecture help user to get their into a request done file connecting with database


.We choose the database architecture based on the following factures 

1.Size of the database                                                                            2.Number of users                                                                                3.Relationship between the users 

.Type of database architecture                                                            .There are various types of database architectures that we use to the  according in the requirements


  

1.One tier architectures:-In one tier architecture the database is the directly available to the user .in one tier architectures the client and  database is prevent in one machine .one tier architecture is not for in integers industrial basically industry prefer two tier or three tier and a architectures  

.Advantages of One tier architecture                                                  1.Simple architecture                                                                              2.Cost effective                                                                                      3.Easy to implement                                                                  

2.Two tier architecture:-It is similar to the client server model side  .In this the application client side  client directly communications to with data base or server services API, like IDBC are used for this is communication in that architectures client side application is the may estabilished connection between server side application database      .The main aim of this architecture is maintanance and understanding easy  

.Advantages of Two tire architecture                                                1.Easy to access                                                                                    2.Scatable                                                                                              3.Low Cost                                                                                          4.Easy to implement and diployment simple

3.Three tire architecture:-In three tire architecture three is another layer between client application and database server. in this low cost architecture client does not communication directly with server for a instead of it interact with the application server layer and this then to they application server communicate with database server. This layer act as a intermediately for exchange of partial information between the client and server  

.Advantage of Three tire architecture                                                1.Enhanced scalability                                                                          2.Data integrity                                                                                      3.Security

What is Constants, Variables, and Data Types

Image
                                          Constants   Constants in java refer to fixed values do not change during the execution of a program , Java support several types  of constants as illustrated. .Integer  Constants      An integer constant refer to a sequence of digits , There are three types integers .namely decimal imager octal integers and hexadecimals integers . Decimal integers consist of a set of thing preceded by an optional minus sign Valid of decimals integer constant  .Variables  A variable is an identifier that denotes a storage location seed to store a data value unlike constant that remain unchanged during the execution of a program , a variable may take different values at different times during the execution of the program ,we had used several variable for instance , we used variables length and breath to store the values o...
