Getting a job is different from getting a perfect job. You may earn a livelihood and spend your time being busy in work, but you might not derive satisfaction unless all your expectations from a job are fulfilled. Not getting a perfect job is a situation that arises not because you are unqualified or incompetent; it happens because you fail to create a good impression on the interviewer. Sometimes, despite all efforts, you fail to secure the job because you are not able to answer all the interview questions and this leaves an impression that you do not have the requisite qualifications. So when the next time you prepare for an interview, it would be better if you spend some additional time in learning about the interview questions an employer asks.
The ADO.NET interview questions are inclusive of two types of questions: technical and non-technical. While the technical questions allow the interviewer to know how well versed you are with this technology, the non-technical questions allow the employer to learn more about your personality as a human being and the qualities that add to your knowledge and result in making you a competent professional.
ADO.NET is basically a platform that is made up of different software components and allows the programmers to access and modify data and use the data services. Several applications make use of this platform to access data and the software components allow the applications to retrieve the data in the required format. Thus, the job of an ADO.NET developer is concentrated in making the best use of this technology and maintain and deliver a large database needed for different purposes.
To increase your chances of getting selected for the job, read the ADO.NET interview questions given below.
Question 1: What is ADO.NET consumer and ADO.NET data provider?
Answer: ADO.NET consumers actually refer to the applications that need to access the database, wheres ADO.NET data provider refers to the software components that provide the data by implementing the assigned interface.
Question 2: Name the fundamental objects included in ADO.NET.
Answer: The two fundamental objects in ADO.NET are DataReader and DataSet.
Question 3: How is XML useful for ADO.NET?
Answer: Through XML, it is possible for the ADO.NET framework to provide offline access to the data.
Question 4: Define object pooling.
Answer: Object pooling is a process through which an object is stored in memory so that it can be reused as and when required. The advantage of object pooling is that it helps the users to allocate an object from the pool, thus minimizing the time that would actually be spent in creating a new object as well as improving the systems' performance.
Question 5: Is it possible to update the records in database using datareader?
Answer: No. The datatreader only allows to read the data.
Question 6: What is the use of DataViewManager?
