in clusterd index the system will sort the row of a table whe there is a chage made to the index. Or in other word, when you use the cluster index, the rows in the table will be in the same order as that of the index. Cluster index controls the physical location of data.
Search results are quicker when records are retrieved by the cluster indexother indexes that use fields that are a part of the cluster index might use less data space

What are some alternative methods for optimizing database rows to improve performance?
Some alternative methods for optimizing database rows to improve performance include indexing columns frequently used in queries, denormalizing data to reduce joins, using partitioning to manage large datasets, and optimizing queries by avoiding unnecessary operations.
What is simple indexing?
Simple indexing is a method used in databases and information retrieval systems to quickly locate and access data. It involves creating an index that maps keys or identifiers to their corresponding data records, allowing for efficient searching and retrieval. This technique enhances performance by reducing the amount of data that needs to be scanned, making queries faster and more efficient. Simple indexing is commonly used in various applications, including databases, search engines, and file systems.
What are the key concepts covered in the Fundamentals of Database Systems 7th Edition?
The key concepts covered in the Fundamentals of Database Systems 7th Edition include database design, normalization, SQL queries, transaction management, indexing, and data warehousing.
What are the four main types of queries?
The four main types of queries are select queries, action queries, parameter queries, and aggregate queries. Select queries retrieve data from one or more tables based on specified criteria. Action queries modify data, such as updating, deleting, or inserting records. Parameter queries prompt users for input to filter results dynamically, while aggregate queries perform calculations on data, such as summing or averaging values.
What is a codgers queries called?

How Search Engine?
The search engine has a three-step work mechanism. Crawl, fetch and index. When a website is available online, the search engine algorithms reach the website and analyze the website content, structure and other technicalities, that are crawling. Next, fetch. Fetch is a mechanism that search engines sort and arrange the analyzed website details and store in their backend database. Last is indexing. Indexing is the process of listing in search of matching queries in search by the user.
What is queries?
Query is a statement which user gives in database.
Does Google queries keywords have to be capitalized?
No. Queries do not need to be capitalized.
Delete queries are often run after queries have added those same records to history tables?
No, Delete queries are ran before the queries which adds the data to history table. This is to avoid duplicacy.
How does database management software interrogate a database?
Database management software interrogates a database by sending queries written in a specific database query language (e.g., SQL) to retrieve, update, and manipulate data. The software processes these queries to access the database and perform the requested operations efficiently. It uses mechanisms like query optimization and indexing to improve performance and ensure data integrity.
