ADMIN TOOL BASICS

Admin tool is the Utility in OBIEE where we can do all the Metadata Development . Some of the functionalities that Admin tool covers are

Dimension Modeling (Physical And Logical)

Security

Cache management

Session View

Database request

Designing Variables

Multi user Development Management

OBIEE Architecture and Physical Layer 5

ADMIN TOOL BASICS (Contd..)The Meta Data Design in OBIEE is split into following 3 Layers

Physical Layer

• DB connections

• DB parameter Settings

• Physical data Model

Business Model Layer (BMM)

• Logical Data Model

• Dimension Hierarchies

• Aggregate Navigation

• Fragmentation

• Level Based Measures

Presentation Layer •Arranging Presentation tables (User Experience)

• Object level Security

• Aliases

ISOLATION LEVEL

The following are the different isolation levels

Committed Read

Allows to insert new records and allows to update the records that a transaction is using and would reflect only after commit, In other words data can be changed before end of transaction resulting in non repeatable reads.

Repeatable Read

Allows to insert new records and places the locks on the al the data that is used in the query to prevent anybody else updating the data.

Serializable

Locks the dataset and does not allow to insert or update the data set until the transaction is complete.

Dirty read

With this option it is possible to read uncommitted data and have rows appear and disappear before end of transaction
