TTASKS OF DBADBA

TTASKS OF DBA: D DATABASE D DESIGN

• the DBA must understand – relational design practices. – relational theory and the specific implementation of the relational database

management system (RDBMS)– conceptual and logical data modeling techniques. The ability to create and interpret

entity-relationship diagrams is essential to designing a relational database.

TType of DBA

• System DBA – A system DBA focuses on technical rather than

business issues, primarily in the system administration area

– Indeed, the job of system DBA usually exists only if the organization does not have an official system administration or systems programming department.

• Database Architect – The database architect is involved in new design and

development work only.

• Database Analyst– Sometimes junior DBAs are referred to as

database analysts. – Sometimes a database analyst performs a role

similar to that of the database architect.– Sometimes the data administrator is referred to

as the database analyst or perhaps as the data analyst

• Data Modeler – A data modeler is usually responsible for a

subset of the DA's responsibilities

• Application DBA – contrast to the system DBA is the application

DBA. – The application DBA focuses on database design

and the ongoing support– administration of databases for a specific

application or applications. – The application DBA is likely to be an expert at

writing and debugging complex SQL

• Task-Oriented DBA – quite rare outside of very large IT shops. – One example of a task-oriented DBA is a backup-

and-recovery DBA who devotes his entire day to ensuring the recoverability of the organization's databases.

– The performance analyst is usually the most skilled, senior member of the DBA staff.

• Data Warehouse Administrator – DBAs specifically to monitor and support the data

warehouse environmen
