Relational databases store data in structured tables, allowing for complex queries and relationships between data entities.
Data is organized in tables (e.g., Customers, Orders) with rows and columns.
Each table has a primary key that uniquely identifies each record (e.g., CustomerID).
Tables can be related through foreign keys, enabling data integrity (e.g., Order table referencing CustomerID).
SQL (Structured Query ...
In the Southeast market, the pole not required for PLA is the cold pole, as it doesn't influence the production process.
PLA (Polylactic Acid) production typically requires heat for polymerization.
The cold pole is not necessary as it does not contribute to the thermal processes.
In contrast, the hot pole is essential for maintaining the required temperatures.
For example, in extrusion processes, maintaining heat is c...
Smoke testing checks basic functionality, while sanity testing verifies specific functionalities after changes. Both are part of regression testing.
Smoke Testing: A preliminary test to check if the basic functions of an application work. Example: Verifying if the application launches.
Sanity Testing: A focused test to ensure that specific functionalities work after changes. Example: Testing a new feature after a bu...
What people are saying about Amdocs
Agile is an iterative approach to software development that emphasizes flexibility, collaboration, and customer feedback.

Priority refers to the urgency of fixing a defect, while severity indicates the impact of the defect on the system.
Priority is about the order in which defects should be fixed, while severity is about the impact of the defect.
High severity defects may not always be high priority. For example, a critical bug in a rarely used feature may be severe but low priority.
Conversely, a minor defect in a key feature may be h...
AD typically refers to Active Directory, a directory service for Windows domain networks.

It stores information about members of the domain, including devices and users.
AD allows for centralized management of user accounts and security policies.
Example: An organization can use AD to enforce password policies across all user acc...
IMAP (Internet Message Access Protocol) is a protocol for accessing and managing email on a remote mail server.
IMAP allows users to access their email from multiple devices while keeping messages synchronized.
Unlike POP3, IMAP does not download emails; it keeps them on the server.
IMAP supports folder management, allowing users to organize emails into different folders.
Example: A user can read an email on their pho...
A VBA program can filter Excel data based on two columns and transfer the results to another sheet efficiently.
Use the AutoFilter method to filter data based on criteria from two columns.
Example: Filter Column A for 'Sales' and Column B for '2023'.
Copy the visible filtered data to a new sheet using the Range.Copy method.
Ensure to clear previous data in the destination sheet before copying new data.
DAX in Power BI enables advanced data analysis through calculated columns, measures, and filtering.
Calculated Columns: Create new data columns using DAX formulas, e.g., 'Sales[Total Sales] = Sales[Quantity] * Sales[Unit Price]'.
Measures: Define calculations that aggregate data dynamically, e.g., 'Total Revenue = SUM(Sales[Total Sales])'.
Time Intelligence: Use DAX functions for date calculations, e.g., 'YTD Sales =...

- Q1. For insertion and deletion which list u use?why?
- Ans.
I use LinkedList for insertion and deletion as it provides constant time complexity.
LinkedList provides constant time complexity for insertion and deletion operations.
ArrayList provides linear time complexity for these operations.
LinkedList is preferred when frequent insertion and deletion operations are required.
ArrayList is preferred when frequent access to elements is required.
- Q2. Custom exception
- Q3. Association means what?
- Ans.
Association refers to a relationship between two or more objects where they are connected or linked in some way.
Association is a fundamental concept in object-oriented programming.
It is used to represent a relationship between two or more objects.
The relationship can be one-to-one, one-to-many, or many-to-many.
For example, a car has an association with its engine, as it cannot function without it.
Another example is a s...
- Q4. Thread life cycle?
- Ans.
The thread life cycle in Java consists of several states that a thread can be in during its execution.
NEW: A thread is created but not yet started. Example: Thread t = new Thread();
RUNNABLE: The thread is ready to run and waiting for CPU time. Example: t.start();
BLOCKED: The thread is waiting for a monitor lock to enter a synchronized block.
WAITING: The thread is waiting indefinitely for another thread to perform a par...
- Q5. Diff between truncate and delete
- Ans.
Truncate removes all data from a table while delete removes specific rows.
Truncate is faster than delete as it doesn't log individual row deletions.
Truncate cannot be rolled back while delete can be.
Truncate resets the identity of the table while delete doesn't.
Truncate doesn't fire triggers while delete does.
- Q6. Write query to delete record
- Ans.
Query to delete record in SQL
Use DELETE statement with WHERE clause to specify the record to be deleted
Make sure to backup data before deleting
Example: DELETE FROM table_name WHERE column_name = value;
- Q7. Prog merge two list
- Ans.
Merging two lists in Java
Create a new list to hold the merged result
Iterate through both lists and compare elements
Add the smaller element to the new list and move to the next element in that list
Repeat until all elements have been added to the new list
Return the new merged list
- Q8. FindNon duplicate element in string prog?

- Q2. What is the internal working mechanism of a HashMap?
- Ans.
HashMap is a data structure that stores key-value pairs and uses hashing to quickly retrieve values based on keys.
HashMap internally uses an array of linked lists to store key-value pairs.
When a key-value pair is added, the key is hashed to determine the index in the array where the pair will be stored.
If multiple keys hash to the same index (collision), a linked list is used to store these pairs.
To retrieve a value, t...
