DESIGN THE ARCHITECTURE of DATA BASES

CLARIFYING USE of DATA BASES

Modul 19 Design The Web of Data Base For Content Of Server


1. Competitor diklat able to design database according the target

2. Competitor diklat able to implementation database system

Target Activity of Study


In determining requirement system of Data bases is not quit of how

in fact that data bases is designed


Facilitating congeniality of information structure

Target of database Scheme

Supporting process requirement and some obyek appearance ( response time, processing time, and storage space

To fulfill information comprising requirement user peculiarly and its applications

PHASE of DATABASE SCHEME


Peculiarly process the scheme comprise 2 parallel activity

Scheme from content of data and database structure

Scheme of Process of and database software application


Process the Database Scheme

I Data collecting and analyze

VI System implementation Database

II Database scheme conceptually

III Election DBMS

IV Database scheme logically ( data model mapping )

V Database scheme in physical


Activities of data collecting and analyze

I. Data collecting and analyze

- Questionnaire and interview

- Environmental analysis operate for and data

process

- Existing Documentation sighting

- Activities of data collecting and analyze


Phase of database Scheme conceptually have two parallel activity

II. Database scheme conceptually

- Transaction scheme

- Conceptual Scheme


Economic factors and organization influencing one another in election DBMS

- The available of seller service

- Data structure

III. Election DBMS

- Personal which have accustomed to an system


Its mapping can be processed in 2 level

IV. Database scheme logically ( mapping model data )

- mapping System-Independent

- Scheme adjustment to specific DBMS


V. Database scheme in physical

Some guide in election database scheme in physical

- Response time

- Space utility

- Transaction throughput


VI. System Implementation Database

Specification is conceptually tested and attributed to [by] a code program

with the commands from embedded DML which have been writted and tested


Question :Mentioning process – process scheme

of database !

DETERMINING PROCEDURE RECOVERY


HOME


1. Competitor diklat able to determine the correct procedure of recovery

2. Competitor diklat knew the technique in procedure recovery


HOME


Transaction Recognition and the Process

TRANSACTION REPRESENT THE LOGIC UNIT [of] FROM DATABASE PROCESS INCLUDING ONE OR

MORE OPERATE FOR TO ACCESS THE DATABASE COVER THE INSERT, DELETE, MODIFICATION

OR OPERATE FOR RETRIEVE


- ROLLBACK (or ABORT)

- COMMIT_TRANSACTION

- READ or WRITE

Status of Transaction and Additional Operation

- BEGIN_TRANSACTION


Transaction Process

Begin Transaction

End Trancaction Commit

Abort Abort

Read, Write


Recovery Concept

Recovery from a transaction failure usually mean database in restore to

consistent status to time before happened failure


Especial Technique In Recovery

I. Deferred update

II. Immediate update


Idea from protocol update delayed

I. Deferred update

A transaction cannot change the database at disk till reach the dot point

A transaction cannot reach the dot point till all operation update kept in logarithm and writed to

disk


Two Operation Recovery At Deferred Update

Recovery updated is delayed at single-user

Recovery update delayed executed is concurrent at multi-user


Operate for the REDO have the nature of idempotent, that is execute recurring that

happened- repeat is equal to once just execute

Procedure of REDO


Advantage from method or algorithm NO-UNDO / redo is transaction operation have

never been required not to become executed

Excess of Method REDO


Transaction do not note all changes in in database at disk reach the point commit

Reason

Transaction will never read the value writted by transaction which not yet commit


II. Immediate update

In this technique, database will be updated by some transaction before transaction

reach the point


Shadow Paging

This scheme Recovery do not require the logarithm use at single-user. At multiuser, a

logarithm required for the method of concurrent control


Question :Mentioning status of transaction

and additional operation in process recovery !

DESIGN THE ARCHITECTURE

OF DATA BASES


HOME


1. Competitor diklat able to comprehend the type of data independence

2. Competitor diklat knew levels in data bases


HOME


Especial target from system of data bases is provide the wearer of through an

abstraction view of concerning data, by hiding detail from how data kept and

manipulate

Target of System Data Bases


Level of Architecture of data Bases

- External Level

- Conseptual Level

- Internal Level


Level Architecture of data Bases


Independence Data

Especial target from 3 architecture level is look after the independence data

Type of Independence Data

- Physical Data Independence

- Logical Data Independence


Scheme of Data Bases


Principle of Data independence is one of matter which must be applied in management of system of

data bases with reason

•DBA can alter the content, location, materialization in organization of data bases without bothering application program

•Factory / equipments agent / software of data processing can introduce the new product without bothering application program

•To remove the application program growth


Question :There is 3 level in architecture of data bases aim to

differentiate the way of wearer approach to data bases and way of making data bases in physical

Mentioning and decripcting level of the data bases architecture !

CLARIFYING USE OF

DATA BASES


HOME


1. Competitor of diklat can implementation data bases in the Multimedia and Internet


HOME


I Data bases for the Multimedia

Application of Data Bases

- Universal Resource Locator (URL)

II Data bases for the internet

- Web Display Language

- Web Server


I. Data bases for the Multimedia

Condition which must be full filed by if on file data multimedia in data bases

•Data bases have to can accommodate the big object

•Existence of facility for the intake of data of pursuant to looking like ( similarity-based retrieval) what is needed by a lot of application of basisdata multimedia


II. Data bases for the Internet World Wide Web ( WWW) represent the system

of distribution information being based on hypertext. Document becoming especial

unsure in web can be expressed in a few type. most type of popular is document hypertext


Universal Resource Locator (URL)

System Hypertext contain the consequence of about existence of depository of pointer ( indicative [of] location) to document place reside in. In web, this function pointer is

given by Universal of Resource Locator ( URL)

http://www.smkn5malang.sch.id

Example :


When a server HTTP accept demand for certain document intake, server execute the program

and deliver the document HTML yielded by a the program. Farther, client web can deliver the

additional argument to be used by program at the (time) of executing

Web Server


Language for the text of markup language, like Standard of Generalized Markup

Language ( SGML), develop, build to fill the blankness of among artless text and

description page yard by order of formatting text

Web Display Language


Question:Mentioning condition must be fullfield if

mutimedia data saved in data base !
