Find Interview Questions for Riktam technologies

Right Answer:
Performance tuning in ABAP involves optimizing the code and database access to enhance the efficiency and speed of ABAP programs. To improve performance, you can:

1. Use efficient SQL queries (e.g., SELECT only necessary fields).
2. Minimize database accesses (e.g., use internal tables).
3. Avoid nested loops and use hash tables for faster lookups.
4. Utilize buffering for frequently accessed data.
5. Optimize the use of SELECT statements with proper WHERE conditions.
6. Use appropriate data types and structures.
7. Analyze and optimize the runtime using transaction ST05 (SQL Trace) and ST12 (Performance Analysis).
8. Implement parallel processing where applicable.

Right Answer:
Alfresco integrates with external systems like SAP or Salesforce primarily through:

* **CMIS (Content Management Interoperability Services):** A standard protocol for accessing content repositories.
* **REST APIs:** Alfresco provides REST APIs for interacting with its functionalities.
* **Custom Integrations:** Developing custom integrations using Java, JavaScript, or other programming languages to connect directly with system APIs or databases.
* **Pre-built Connectors/Modules:** Alfresco Marketplace may offer pre-built connectors for specific systems.

Right Answer:
EME (Enterprise Meta>Environment) is a metadata management tool in Ab Initio that stores, manages, and retrieves metadata related to data processing applications. It provides a centralized repository for metadata, allowing users to track data lineage, manage data definitions, and facilitate collaboration among teams by maintaining version control and documentation of data assets.

Right Answer:
Functional programming focuses on using functions and immutable data, emphasizing the evaluation of expressions rather than execution of commands. Procedural programming, on the other hand, is based on the concept of procedure calls, where programs are structured as a sequence of instructions or procedures that manipulate data.

Right Answer:
To implement custom workflows in AEM, follow these steps:

1. **Create a Workflow Model**: Use the AEM Workflow Model Editor to design your workflow. Define the steps and the order in which they will execute.

2. **Add Workflow Steps**: Include custom workflow processes by creating Java classes that extend `WorkflowProcess`. Implement the `execute` method to define the logic for each step.

3. **Register the Workflow Process**: Use the OSGi configuration to register your custom workflow process in AEM.

4. **Create a Workflow Launchers**: Set up workflow launchers to trigger the workflow based on specific events or conditions, such as content creation or modification.

5. **Test the Workflow**: Deploy your workflow and test it to ensure it functions as expected.

6. **Monitor and Debug**: Use the AEM Workflow console to monitor the execution and debug any issues that arise.

Right Answer:
1. **Performance**: Stored procedures are precompiled, which can lead to faster execution.
2. **Reusability**: They can be reused across multiple applications, reducing code duplication.
3. **Security**: They provide a layer of security by restricting direct access to the underlying tables.
4. **Maintainability**: Changes can be made in one place without affecting the application code.
5. **Reduced Network Traffic**: They can execute multiple SQL statements in a single call, minimizing data transfer.
6. **Transaction Control**: They allow for better management of transactions and error handling.

Right Answer:
```sql
CREATE PROCEDURE CreateGuidAndInsert
@NewGuid UNIQUEIDENTIFIER OUTPUT
AS
BEGIN
-- Generate a new GUID
SET @NewGuid = NEWID();

-- Insert the GUID into the table (replace 'YourTable' with your actual table name)
INSERT INTO YourTable (GuidColumn) VALUES (@NewGuid);
END
```

Right Answer:
JavaScript is a programming language used to create interactive and dynamic content on websites. It allows developers to manipulate HTML and CSS, handle events, and communicate with servers, enhancing user experience and functionality in web development.

Right Answer:
Synchronous code executes sequentially, meaning each operation must complete before the next one starts. Asynchronous code allows operations to run independently, enabling other tasks to proceed without waiting for the previous ones to finish.

Right Answer:
Event bubbling is a JavaScript event propagation method where an event starts from the target element and bubbles up to its ancestors in the DOM hierarchy. Event delegation is a technique that involves attaching a single event listener to a parent element to manage events for multiple child elements, leveraging event bubbling to handle events efficiently.

Right Answer:
Some popular frontend frameworks and libraries are:

1. React
2. Angular
3. Vue.js
4. Svelte
5. Bootstrap
6. jQuery
7. Ember.js
8. Backbone.js

Right Answer:
The box model in CSS describes the rectangular boxes generated for elements in a document tree and consists of four areas: content, padding, border, and margin. The content is the innermost area, surrounded by padding, then the border, and finally the margin, which is the outermost area.

Right Answer:

A VPC (Virtual Private Cloud) is a virtual network dedicated to your AWS account, allowing you to launch AWS resources in a logically isolated environment.

Right Answer:

Auto Scaling is a feature in AWS that automatically adjusts the number of EC2 instances in a group based on demand, ensuring optimal performance and cost efficiency.

Right Answer:

To secure data in transit in AWS, use SSL/TLS for encryption during transmission and implement VPNs or AWS Direct Connect for secure connections. To secure data at rest, use AWS services like S3 Server-Side Encryption, EBS encryption, and RDS encryption, along with IAM policies to control access.

Right Answer:

AWS Lambda is a serverless computing service that allows you to run code in response to events without provisioning or managing servers. It automatically scales and charges only for the compute time consumed.

Right Answer:

AWS, or Amazon Web Services, is a comprehensive cloud computing platform provided by Amazon that offers a wide range of services, including computing power, storage, and databases, as well as machine learning, analytics, and networking, allowing businesses to scale and grow without the need for physical infrastructure.

Right Answer:

Git cherry-pick is a command that allows you to apply the changes from a specific commit in one branch to another branch. You would use it when you want to selectively apply certain commits without merging the entire branch, such as when you need a bug fix or feature from another branch without bringing in all other changes.
