Microsoft SQL Server is a powerful and reliable relational database management system (RDBMS) developed by Microsoft. It is used to store and manage data for a variety of applications and businesses. With SQL Server, organizations can collect and analyze data to make better decisions, improve operations and gain insight from their data.
SQL Server supports a wide variety of data types and can be accessed using a variety of programming languages and tools. It offers advanced features such as in-memory OLTP and columnstore indexes, which can significantly improve the performance of data-intensive workloads. It also includes built-in support for Business Intelligence (BI) and data analytics, as well as support for big data scenarios.
Microsoft SQL Server is available in a number of different editions, including Express, Web, Standard and Enterprise, each with their own features and capabilities. It can run on various operating systems, including Windows, Linux and macOS, and supports both physical and virtual environments.
SQL Server is widely used in various industries and is a popular choice for managing data in enterprise environments. It also integrates with other Microsoft products and technologies, such as Azure, SharePoint and Power BI, providing seamless integration of data and analytics in the cloud or on-premises. Obtaining a Microsoft SQL Server certification can open the door to a variety of job opportunities for ICT professionals in the field of data management and analytics.
Microsoft SQL Server manages and stores data in a relational database. A relational database is a collection of tables, each containing rows (also known as records or tuples) and columns (also known as fields or attributes). The tables in a relational database are related to each other through a process called normalization, which divides the data into multiple tables and establishes relationships between them using keys.
When a user wants to access or modify the data in the database, he sends a request in the form of a Structured Query Language (SQL) statement to the SQL Server. The SQL Server processes the SQL instruction, optimizes the execution plan and opens the data in the appropriate tables. The results of the query are then returned to the user. SQL Server also provides a number of services to manage and maintain the database, including security, backup and recovery, and performance monitoring.
SQL Server uses a storage engine to store and retrieve data. The storage engine is responsible for reading and writing data to and from disk, as well as managing the data pages in memory. It also manages indexes, which are used to improve the performance of queries by allowing the database to quickly find specific rows of data.
SQL Server also provides a number of advanced features, such as support for in-memory OLTP and columnstore indexes, which can significantly improve the performance of data-intensive workloads. It also includes built-in support for Business Intelligence (BI) and data analytics, as well as support for big data scenarios through the use of technologies such as PolyBase and HDFS (Hadoop Distributed File System). SQL Server also provides a number of tools for administrators and developers to manage and work with the database, such as SQL Server Management Studio and SQL Server Data Tools. These tools allow you to perform tasks such as creating and modifying tables, running SQL queries and monitoring database performance.
One of the most important steps in preparing for a Microsoft SQL Server certification exam is becoming familiar with the exam skills overview. Studying is an essential part of preparing for a certification exam. To be fully prepared for the exam, OEM offers several SQL Server training courses.
Microsoft has strict rules regarding the types of study aids to prepare for its exams. The company will invalidate a certification if it determines that the exam participant used a tool with real exam questions, such as so-called "brain-dump" sites or practice exams from questionable sources. Training through OEM is always legitimate, official and an excellent preparation for the actual Microsoft SQL Server exam.
Here is an overview about taking exams for Microsoft SQL Server certifications:
Microsoft SQL Server certification exams are usually multiple-choice and may include some performance-based tests. The exams are designed to test your skills and knowledge in specific areas of SQL Server and may include hands-on exercises, simulations and scenario-based questions.
You can register for a Microsoft SQL Server certification exam through the Microsoft website. You need to create a Microsoft account and then purchase the exam. Exam training courses you reliably follow through OEM.
The cost of a Microsoft SQL Server certification exam may vary depending on the country where you are taking the exam.
OEM offers several resources to help you prepare for certification exams, including instructor-led training, self-study and practice tests. We have several high-quality training courses available to fully prepare you for any exams.
Exam retake policy
If you fail the exam, you can retake it after a certain period of time. However, the retake policy may vary from exam to exam.
Microsoft SQL Server certifications are valid for a certain period of time and you must renew it to keep it current. The renewal process includes taking a new exam or meeting certain other requirements.
It is important to know that information about certification exams can change as needed. In addition, it is also good to know that passing the exam is only one step because it is important to have the practical experience and skills to perform the work.
