Part 1: Accounts Receivable



1.It is built on ETL in architecture

1.It is built on  ELT in architecture

2.Extract, Transform, and Load (ETL) is a process that involves extracting data from outside sources, transforming it to fit operational needs (sometimes using staging tables), then loading it into the end target database or data warehouse

2.Extract, Load, and Transform (ELT) is a process where data is extracted for the source, then loaded into a staging table in the database, transforming it where it sits in the database and then loading it into the target database or data warehouse.

3.It can achieve ELT functionality up to 30% through  the concept of "push down optimization"

3.It can achieve 100% ELT functionality

4. It extract the  data from database servers  into ETL server engine

4.It cannot pull the data  to the out of data base server ODI engine 

5. Maintenance cost for the high end server is very high when compared to ELT tools.

5. Where as in ODI No additional server is required for processing the data, why because data bases are meant for data processing and maintenance only.

6. It converts    data types of source   to its  "Native data types" while extracting  data from source  to load into the target  ,through the use  of "source qualifier transformation"

6. It need not to convert the data types of source   to its "engine” corresponded data types, why because heterogeneous data bases can communicate through the use  of ANCI SQL Code .  

7.Unable utilize the relational database management system capabilities and file structures without any issue.

7. Able to work with different relational Database management systems and file structures without any issue.

8. Due to its Conventional Extract Transform and Load (ETL) tool cannot offer the performance and reduces data integration costs even across the homogeneous Systems.

8. ODI offers unique, next-generation Extract Load and Transform (ELT) technology that improves performance and reduces data integration costs, even across heterogeneous systems.

9.Development  time for the project is more, due to the absence of "Declarative Design” here

9. Declarative Design (Only need to define business rules and use a Knowledge Module (reusable template of code) for the implementation) reduces the development time.

10. Informatica repository can be installed on its own database other than source and target data bases.

10.The ODI modular repositories (Master + and one of multiple Work repositories) can be installed on any database engine that can be either source or target that  supports ANSI ISO 89 syntax such as Oracle, Microsoft SQL Server, Sybase AS Enterprise, IBM DB2 UDB, IBM DB2/40.

 11. Code customization is very difficult here.

11. In case of ODI, It is very easy to customize the code by the core component is called "Knowledge module” (KM).
