Right Answer: Open SQL is a database-independent SQL interface provided by SAP that allows developers to write queries without worrying about the underlying database system. It translates the queries into the appropriate SQL dialect for the specific database being used.
Native SQL, on the other hand, refers to the SQL syntax specific to a particular database management system (DBMS). It allows for the use of advanced features and optimizations specific to that DBMS but is not portable across different systems.
Right Answer: LIS stands for Laboratory Information System, which is a software system that manages and processes laboratory data, including test orders, results, and patient information.
Right Answer: Second Normal Form (2NF) is a database normalization level where a table is in First Normal Form (1NF) and all non-key attributes are fully functionally dependent on the entire primary key, meaning there are no partial dependencies on a composite primary key.
Right Answer: Denormalization should be considered when you need to improve read performance, reduce the complexity of queries, or when you have specific reporting requirements that benefit from fewer joins in the database.
Right Answer: BI stands for Business Intelligence, which involves analyzing data to help make informed business decisions. For OLAP (Online Analytical Processing) reporting, a star schema or snowflake schema is suitable because they optimize query performance and simplify data retrieval.
Steps to create a database:
1. Define the purpose and requirements.
2. Design the schema (tables, relationships).
3. Choose a database management system (DBMS).
4. Create the database and tables using SQL.
5. Populate the database with data.
6. Implement indexing for performance.
7. Test the database for functionality and performance.
Right Answer: First Normal Form (1NF) is a property of a relation in a database that ensures all columns contain atomic, indivisible values, and each entry in a column is of the same data type. Additionally, each row must be unique, typically achieved by having a primary key.
Right Answer: I handle shifting priorities by staying flexible and open to change. I prioritize tasks based on the new requirements, communicate with my team to ensure everyone is aligned, and adjust my workflow to accommodate the changes while maintaining focus on project goals.
Right Answer: In my previous job, I worked with a colleague who preferred detailed written communication over verbal discussions. To adapt, I started sending more comprehensive emails and reports, ensuring I included all necessary information. This change helped us collaborate more effectively and improved our project outcomes.
Right Answer: I prioritize tasks based on urgency and importance, maintain clear communication with my team and stakeholders, and stay flexible by adjusting my plans as needed. I also set personal milestones to track progress and ensure quality remains high despite changes.
Right Answer: I keep my skills up to date by regularly attending workshops and webinars, following industry news and trends, taking online courses, and participating in professional networks and forums.
Right Answer: Adaptability in a professional setting means being open to change, adjusting to new situations, and being flexible in response to challenges or shifting priorities while maintaining productivity and effectiveness.
