Example: “When developing Essbase applications, there are a number of scalability considerations that need to be taken into account. These include:
-The size of the data set that will be processed by the application.
-The number of users who will be using the application.
-The amount of customisation and configuration that will be required for the application.
-The performance requirements of the application.”
What security features do you typically implement for Essbase applications?
The interviewer is asking this question to assess the Essbase Developer's knowledge of security features and how they can be used to protect Essbase applications. It is important for the interviewer to know this because it will help them determine if the Essbase Developer is able to properly secure Essbase applications and prevent unauthorized access.
Example: “There are a few different security features that can be implemented for Essbase applications. The most common ones are user authentication and authorization, data encryption, and application-level security. User authentication is typically done using a username and password, while authorization controls what users can do within the application. Data encryption ensures that information stored in the database is secure, and application-level security restricts access to certain areas of the application.”
What data loading and ETL strategies do you use for Essbase applications?
There are a few reasons why an interviewer might ask this question:
1. To gauge the developer's understanding of how data is loaded into Essbase applications. This is important because it can impact the performance of the application.

3. To determine if the developer is using best practices for data loading and ETL. This is important because it can impact the stability of the application and the data.
Example: “There are a few different ways to load data into Essbase, and the best strategy depends on the specific application and data set. For smaller data sets, it is often easiest to simply use the Essbase Data Load wizard to load data directly from a flat file. For larger data sets, it is usually more efficient to use an ETL tool such as Informatica or DataStage to extract data from the source system, transform it into the appropriate format, and then load it into Essbase.”
What reporting and analysis tools do you use in conjunction with Essbase?
There are many possible reasons why an interviewer would ask this question to an Essbase Developer. Some possible reasons include:
-To gauge the Essbase Developer's level of experience with using reporting and analysis tools in conjunction with Essbase.
-To assess the Essbase Developer's ability to use different reporting and analysis tools to generate insights from Essbase data.
-To determine whether the Essbase Developer is familiar with using a variety of reporting and analysis tools to create custom reports and dashboards.
The ability to use reporting and analysis tools in conjunction with Essbase is important because it allows developers to create custom reports and dashboards that can provide valuable insights into an organization's data. Additionally, using different reporting and analysis tools can help developers to identify trends and patterns that may not be immediately apparent when looking at data from just one perspective.
Example: “There are a number of reporting and analysis tools that can be used in conjunction with Essbase, including Oracle BIEE, Cognos, Business Objects, and Microsoft Excel. Each of these tools has its own strengths and weaknesses, so it is important to choose the right tool for the job at hand. In general, Oracle BIEE is the most comprehensive tool and offers the greatest flexibility, while Excel is the simplest and most widely-used tool.”
How do you handle versioning and change management for Essbase applications?

There could be several reasons why an interviewer would ask this question to an Essbase developer. One reason might be to gauge the developer's understanding of the product and its future direction. Another reason might be to get a sense of the developer's level of experience and expertise. It is important for the interviewer to understand the challenges that the Essbase developer sees in the future so that he or she can make an informed decision about whether or not to hire the developer.
Example: “There are several challenges that we see for Essbase development in the future. One challenge is the increasing complexity of data sets. As data sets continue to grow in size and complexity, it becomes more difficult to develop efficient algorithms that can extract meaningful information from them. Another challenge is the need to develop more user-friendly interfaces. As Essbase becomes more widely used, there is a greater need for interfaces that are easy to use and understand. Finally, there is a need for better integration with other enterprise applications. As businesses become more reliant on data from multiple sources, it becomes increasingly important to be able to easily integrate Essbase with other applications.”
What trends are you seeing in the world of Business Intelligence and Data Warehousing?
There are a few reasons why an interviewer might ask this question to an Essbase developer. First, it shows that the interviewer is interested in knowing what trends the developer is seeing in their field. This can help the interviewer gauge the developer's level of expertise and knowledge. Additionally, it can help the interviewer understand how the developer keeps up with changes in their field. Finally, this question can also help the interviewer understand the developer's thoughts on the future of Business Intelligence and Data Warehousing.
Example: “There is a growing trend towards self-service Business Intelligence (BI) and data warehousing. This means that users are able to access and analyze data without having to go through a centralized IT department. This trend is being driven by the increasing availability of powerful data visualization and analysis tools, as well as the growing popularity of cloud-based BI and data warehousing solutions.
Another trend that is becoming more prevalent is the use of in-memory databases for BI and data warehousing. In-memory databases allow for much faster data access and analysis than traditional disk-based databases. This can be a major advantage when working with large data sets.
Finally, there is a trend towards using BI and data warehousing solutions for predictive analytics. Predictive analytics can help organizations to make better decisions by using historical data to predict future trends.”
How does Essbase fit into the overall BI landscape?
An interviewer would ask "How does Essbase fit into the overall BI landscape?" to a/an Essbase Developer in order to gauge the candidate's understanding of how their tool of choice integrates with other systems and tools in a business intelligence context. This question is important because a comprehensive understanding of the BI landscape is necessary for developing effective solutions that meet business needs.
Example: “Essbase is a multidimensional database management system (MDBMS) that provides a platform for building analytical applications. It is often used as a component in business intelligence (BI) systems.
Essbase can be used to store and analyze data from various sources, including relational databases, flat files, and OLAP cubes. It supports a variety of data models, including star schema, snowflake schema, and hybrid schema. Essbase also provides a number of features for managing and analyzing data, such as dimensionality reduction, data compression, and query optimization.
Essbase is typically used to support decision-making processes by providing quick access to accurate and up-to-date information. It can be used to answer questions such as "What were our sales last quarter?" or "What are the trends in our customer satisfaction scores?"
Essbase is often used in conjunction with other BI tools, such as reporting and data visualization tools. It can also be integrated with enterprise resource planning (ERP) systems and other back-end systems.”
