ETL stands for Extract-Transform-Load and it is a process of how data is loaded from the source system to the data warehouse. Data is extracted from an OLTP database, transformed to match the data warehouse schema and loaded into the data warehouse database.Many data warehouses also incorporate data from non-OLTP systems such as text files, legacy systems and spreadsheets.
Conventional testing is a sort of testing in which the test engineers will check the developed application or its related parts are working accordingly to the expectations of customer or not, from coding phase of SDLC to the end

What is the difference between alpha testing and acceptance testing?
Alpha testing is always performed by the developers at the software development site. acceptance testing is a test conducted to determine if the requirements of a specification or contract are met.
In testing for differences between the means of two related populations the null hypothesis is?
That there is no difference between the means for the two populations.
Difference between alpha testing and beta testing?
Alpha Testing is always performed at the time of Acceptance Testing when developers test the product and project to check whether it meets the user requirements or not.Beta Testing is always performed at the time when software product and project are marketed.
What is non-directional research hypothesis?
A non-directional research hypothesis is a kind of hypothesis that is used in testing statistical significance. It states that there is no difference between variables.
The statistical distribution used for testing the difference between two population variances is the BLANK distribution. The choices are a t b standardized normal c binomial d F?

What is the difference between object oriented testing and conventional testing?
Conventional testing is the traditional approach to testing mostly done when water fall life cycle is used for development, while object oriented testing is used when object oriented analysis and design is used for developing enterprise software. Conventional testing focuses more on decomposition and functional approaches as opposed to object oriented testing, which uses composition. The three levels of testing (system, integration, unit) used in conventional testing is not clearly defined when it comes to object oriented testing. The main reason for this is that OO development uses incremental approach, while traditional development follows a sequential approach. In terms of unit testing, object oriented testing looks at much smaller units compared to conventional testing

Difference between functionality testing and load testing?
Functionality testing is what is expected. Load testing is what it actually did.
What are the differences between object oriented testing of software and convectional software testing?
Object-oriented testing and conventional software testing differ in several key aspects: Testing Focus: Object-Oriented Testing focuses on testing classes, objects, methods, and interactions between objects. It emphasizes encapsulation, inheritance, and polymorphism. Conventional Testing typically focuses on individual functions, modules, or procedural code without considering object-oriented principles. Test Levels: Object-Oriented Testing involves unit testing individual classes and methods, integration testing between objects, and ensuring correct behavior of class hierarchies. Conventional Testing often focuses on lower-level procedural testing and may not consider interactions between complex structures like objects. Test Design: Object-Oriented Testing requires test cases that validate the behavior of objects, their interactions, and their state changes across method calls. Conventional Testing tests isolated functions or procedures with a focus on input/output correctness. Reusability and Maintenance: Object-Oriented Testing must account for object reusability, inheritance, and polymorphism, which may introduce complexities in testing inherited behaviors. Conventional Testing may be simpler but lacks the depth of testing relationships between entities in object-oriented code. In summary, object-oriented testing is more focused on the complexities of interacting objects, while conventional testing typically emphasizes simpler, procedural code verification.

What is the difference between testing a single mean and testing the difference between two means?
A single mean is used in testing to compare a single variable to a population mean in order to determineÊif there is aÊdifference. Two means are used in testing to compare two populations to see if there are variances between the two variables.Ê
What is the difference between data warehouse testing and traditional software testing?
ETL or Dataware Housing Testing:- ETL stands for Extract-Transform-Load and it is a process of how data is loaded from the source system to the data warehouse. Data is extracted from an OLTP database, transformed to match the data warehouse schema and loaded into the data warehouse database. Many data warehouses also incorporate data from non-OLTP systems such as text files, legacy systems and spreadsheets. Traditional (old) way of software testing: -Requirement -Design -Code & Build -Testing -Maintenance Unfortunately that is an erroneous methodology because the earlier you find an error - the more funds you can save. For example, fixing an error in maintenance is ten times more expensive than fixing it during execution. But many organizations have improved this way of thinking and choose modern way of software testing. In this philosophy testing should take place in every stage.
