C_BOBIP_42 – SAP Certified Application Associate – SAP BusinessObjects Business Intelligence Platform 4.2 Interview Questions
While some interviewers have their own style of asking, the majority of job interviews follow a standard set of questions and responses (including some of the most often-asked behavioral interview questions). Here are some of the most often asked interview questions, along with some of the greatest responses. Consider the following tips for the C_BOBIP_42 – SAP Certified Application Associate – SAP BusinessObjects Business Intelligence Platform 4.2 interview preparation:
Q1)What are the different types of business objects?
Domain objects are what business objects are referred to as. A domain model depicts a collection of domain items and describes their relationships. As a result, a business model will display a set of domain objects as well as their relationships.
Q2)What is the definition of a universe?
Universe is the semantic layer that sits between the database and the person who creates the objects and classes. As a result, the data in the Database will map to the Universe.
Q3)What is the meaning of a bomain.Key?
BOMain.Key is a file that contains all of the repository site’s information. As a result, it will include the entire repository security domain’s address.
Q4)What is a business objects repository, and how does it work?
The word “business objects” refers to items that are use in Only the metadata is stored in the repository. The repository will function similarly to a database. Business objects such as users, data, access styles, and access rights will be store in the Business Object Repository. Objects of commerce A repository is a centralised idea that can store a collection of data structures.
Q5)What have linked universes?
Data from two separate universes is sometimes present, and the data from these two universes can be linked in some way. These universes are known as Linked Universes.
Q6) What is the difference between master-detail and breaks?
Common entities will be removed in Breaks. We shall declare a specific entity as a master in master detail to obtain comprehensive information, or it will report if the table format is alter.
Q7)What are metrics and how do they work?
Metrics are a set of variables. Metrics are a method of assessing a process in a quantitative and periodic manner. Typically, metrics are use to track trends and productivity.
Q8)What do you mean when you say “Universal parameters”?
The universal parameters are the RDBMS connection, size rights, universe name, and description.
Q9)In this universe, what are the user requirements?
Database connections, key columns, join and check for loop if you need measures, metrics are the user’s requirements in this universe. The following are the actions to take: 1. Define the connection.
- Create the objects and classes
- Provide the joins before resolving the loops.
- Create the entire universe.
Q10)How long does it take to set up a repository?
The version will determine how the repository is create. In the 5i/6i versions, the repository will be generate after the software is installed, however in the Xi version, the repository will be created at the time of installation.
Q11) What are the different types of access controls for database rows?
The limitations will also be determine by the Version. This may be done in the XI version by leveraging the designer module’s row-level security. The supervisor is in charge of restricting database access in the 5i/6i versions.
Q12)What are the steps in the data integration process
- Data is staged in a datastore, warehouse, or data mart that is operational.
- In batch or real-time mode, update staged data.
- Create a single development, testing, and deployment environment for the whole data integration platform.
- Manage a single metadata repository to track links between various extraction and access methods and perform integrated lineage and effect analysis.
Q13) Explain what the terms “job,” “workflow,” and “dataflow” mean.
- A task is the smallest unit of work that can be schedule for execution independently.
- The decision-making process for executing data flows is define by a work flow.
- Data flows are use to extract, transform, and load information. A data flow contains everything that has to do with data, including reading sources, altering data, and loading targets.
Q14)What does it mean to transform?
You can use a transform to regulate how datasets in a dataflow change.
Q15)What is the definition of a script?
In a workflow, a script is a one-time use object that is used to call functions and assign values.
Q16)What is a real time job?
Data is “extracted” from the body of the real-time message received and any secondary sources utilised in the job by real-time jobs.
Q17)What is an Embedded Dataflow?
Q18)What is the difference between a data store and a database?
A datastore is a database connection.
Q19) In Data Services, how many different types of datastores are there?
- Database Datastores are an easy way to import metadata straight from a relational database management system.
- Application Datastores: allow users to import metadata from most ERP systems quickly and simply.
- Adapter Datastores: offer access to the data and metadata of an application, or only the metadata.
Q20)What are memory datastores and how do they work?
You can also use Data Services to establish a database datastore with Memory as the Database type. Memory Datastores are develop to improve the processing performance of real-time data flows.
Q21) What are the different file formats in C_BOBIP_42 ?
- A file format is a set of attributes that describe a flat file’s structure (ASCII). The metadata structure is describe by file formats. File format objects can be use to describe files in the following formats:
- Each field is separate by commas or tabs in a delimit format.
- The column width is supplied by the user in a fixed-width format.
- SAP ERP and R/3 formats are available.
Q22)What is the difference between a repository and a datastore?
A repository is a collection of tables that store system objects, source and destination metadata, and transformation rules. A Datastore is a physical connection to a data-holding database.
Q23)What is the difference between a parameter and a variable- in C_BOBIP_42 ?
When a job is called, a parameter is an expression that provides a piece of data to a work flow, data flow, or custom function. A variable is a placeholder for values in a programme.
Q24) When is it better to use a global variable than a local variable in C_BOBIP_42 ?
- When a variable must be utilize several times in a single job.
- When you want to cut down on the time it takes to design task components that pass values between them.
- When you need to construct a dependency between the name of a global variable at the job level and the names of job components.
Q25)What is the substitution parameter in C_BOBIP_42 ?
When a job is migrate to another environment, the value that is consistent in one environment may change.
Q26)What are some possible reasons for a job’s failure to execute in C_BOBIP_42 ?
Incorrect syntax, Job Server not operating, and Designer and Job Server port numbers do not match.
Q27)List the considerations you make when deciding whether to run work or data flows serially or in parallel.
- Take into account the following:
- Whether or not the flows are self-contain. Whether or not the server is capable of handling the processing demands of multiple flows running at the same time (in parallel)
Q28) What is the purpose of a lookup function? What are the differences between the lookup function variations?
For each row in the source, all lookup functions return one row. They choose one of numerous matching rows to return in different ways.
Q29)What do cleaning packages involve in C_BOBIP_42 ?
These are packages that let Data Cleanse analyse various types of global data more accurately by integrating language-specific reference data and parsing rules.
Q30)What are adapters and how do they work in C_BOBIP_42 ?
Adapters are Java-based programmes that can be deploy on the task server to link to other systems like Salesforce.com and the JavaMessagingQueue. Customers can also design adapters for custom applications using a software development Kit (SDK).
