An Oracle Model is a set of datastores corresponding to views and tables contained in an Oracle Schema. A model is always based on a Logical Schema. In a given Context, the Logical Schema corresponds to a Physical Schema.
The Data Schema of this Physical Schema contains the Oracle model’s tables and views.

The Master Repository is a data structure containing information on the topology of a company’s IT resources, on security, and on version management of projects and data models.
This repository is stored on a relational database accessible in client/server mode from the different modules. Generally, only one master repository is necessary.
However, in exceptional circumstances, it may be necessary to create several master repositories in one of the following cases:
Project construction over several sites not linked by a high-speed network (off-site development, for example).
The necessity to clearly separate the interfaces’ operating environments (development, test, production), including on the database containing the master repository. This may be the case if these environments are on several sites.

Each work repository is attached to a master repository, therefore, information about the physical connection to a work repository is stored in the master repository it is attached to.
Defining a connection to a work repository consists of defining a connection to a master repository, then selecting one of the work repositories attached to this master repository.

Variables can be used in all Oracle Data Integrator expressions:ü Mapping,ü Filters,ü Joins,ü Constraints,
Posted Date:- 2021-10-08 04:52:17
The procedure is a step-by-step technology code operation. you can refer What are the types of Variables?
* Global
* Project
A variable is an object that stores a single value. This value can be a string, a number, or a date. The value is stored in Oracle Data Integrator and can be updated at run-time.
The value of a variable can be updated from the result of a query executed on a logical schema. For example, it can retrieve the current date and time from a database. A variable can be created as a global variable or in a project.
Global variables can be used in all projects, while project variables can only be used within the project in which they are defined.

ODI stands for Oracle Data Integrator. It is different from another ETL tool in the way that it uses the E-LT approach as opposed to the ETL approach. This approach eliminates the need for the exclusive Transformation Server between the Source and Target Data server.
The power of the target data server can be used to transform the data. i.e. The target data server acts as a staging area in addition to its role in the target database.
While loading the data in the target database (from the staging area) the transformation logic is implemented.
Also, the use of appropriate CKM (Check Knowledge Module) can be made while doing this to implement data quality requirements.

As mentioned previously, the ODI-EE license includes both ODI and OWB as separate products, both tools will converge in time into “Oracle’s Unified Data Integration Productâ€.
Oracle has released a statement of direction for both products, published January 2010:
OWB 11G R2 is the first step from Oracle to bring these two applications together, it's now possible to use ODI Knowledge modules within your OWB 11G R2 environment as ‘Code
Templates’, an Oracle white paper published in February 2010 describes this in more detail.

Yes, ODI is ‘SOA’ enabled and its web services can be used in 3 ways:
* The Oracle Data Integrator Public Web Service, lets you execute a scenario (a published package) from a web service call.
* Data Services, which provide a web service over an ODI data store (i.e. a table, view, or other data source registered in ODI).
* The ODIInvokeWebService tool that you can add to a package to request a response from a web service.

SCD Slowly changing dimension we are using for to load changing dimension information data.
where are three types of SCD'same
1) SCD TYPE1: No history, we will all columns SCD property as OVERWRITE ON CHANGE in ODI.
SCD TYPE1: we can use IKM Oracle Incremental update KM or we can IKM Slowly Changing Dimension both we can use.
2) SCD TYPE2: Here we can maintain no of times history, so we need to maintain below SCD properties in SCD TYPE 2 table.
1) ADD Row On CHANGE: this property will add a row whenever we are receiving changed data to maintain history.
2) STARTING_ TIME STAMP: This will show record starting date and time
3) Ending Time stamp: this will show record ending date and time
4) RECORD FLAG: this will show active record if it is Y and if it is N for old rows or history rows.
3) SCD TYPE 3: As of now ODI is not supporting we have to customise our IKM Slowly Changing Dimension. it will maintain only one time history in different column like , CURRENT SALARY and PREVIOUS SALARY two columns.

ODI offers a unique design approach through the use of Contexts and Logical schemas. Imagine a development team, within the ODI Topology manager a senior developer can define the system architecture, connections, databases, data servers (tables, etc), and so forth.
These objects are linked through contexts to ‘logical’ architecture objects that are then used by other developers to simply create interfaces using these logical objects, at run-time, on the specification of a context within which to execute the interfaces, ODI will use the correct physical connections, databases + tables (source + target) linked the logical objects being used in those interfaces as defined within the environment Topology.

Yellow interface we are using for without target table and we can create dynamically target table if we dont have target table.for this we need to enable CREATE_TARGET_TABLE option=> TRUE at IKM level.This yellow interface we can use for source table as well.

Logical schema is alias for your physical schemas and it will connect to your physical schemas throgh contexts. In Designer developer can access only logical schemas he con not access physical schemas, developer can access logical schemas and context combination he
can connect physical schemas.

Contexts bring together components of the physical architecture (the real Architecture) of the information system with components of the Oracle Data Integrator logical architecture (the Architecture on which the user works).
For example, contexts may correspond to different execution environments (Development, Test and Production) or different execution locations (Boston Site, New-York Site, and so forth.) where similar physical resource exist.

ODI agent is run time component which orchestrates the data integration process.
They are three types of Agents:

Physical Schema = Logical Schema + Context
For Example: Consider an Organization A whose Branches are A1,A2 and A3.
Consider the Structure of A1,A2 and A3 Schema's are same but located in different Servers. By the EOD all the data stored in A1,A2 and A3 to be stored in A.
For above scenario, developer develops one mapping with one logical Schema , 3 Physical Schema (A1,A2 and A3)and 3 Context (A1_CTX,A2_CTX and A3_CTX) . While executing the mapping if he selects A1_CTX it loads to A1. (i.e., Logical_schema+A1_CTX = A1... ) . That means we can reuse same code to pick data from different schema's.

E-LT is an innovative approach to extracting, loading, and Transforming data. Typically ETL application vendors have relied on costly heavyweight, mid-tier servers to perform the transformations required when moving large volumes of data around the enterprise.
ODI delivers unique next-generation, Extract Load and Transform (ELT) technology that improves performance and reduces data integration costs, even across heterogeneous systems by pushing the processing required down to the typically large and powerful database servers already in place within the enterprise.
