1)What are the different types of constraints in a database and how are they used? Rules that limit the values that may be added to a table are known as constraints in databases. A database may have primary key constraints, foreign key constraints, unique constraints, check constraints, and not null constraints, among other sorts of restrictions. Foreign key constraints ensure that the values in a field match those in another table, whereas primary key constraints guarantee that each row in a table is distinct. While check constraints ensure that values in field match specific requirements, unique constraints guarantee that each ... Read More

One uses the Cassandra Query Language (CQL) when communicating with the Apache Cassandra NoSQL database. Database roles may be defined and rights can be assigned to them using CQL, one of its characteristics. User access and permissions are managed within a database using Cassandra's roles. This article will discuss roles in Cassandra, how they work, and give examples of creating, changing, and removing roles using CQL. What do Cassandra's roles entail? A role in Cassandra is a type of object that specifies a set of rights that may be bestowed upon an individual user or group of users. Access to ... Read More
A software program known as a database management system (DBMS) is used to manage, compile, and store data in a systematic manner. The user and the database are connected through DBMS interfaces. They give users an easy-to-use interface so they may access and change the data that is stored in the database. There are several DBMS interface types, each created to meet certain user requirements. The most typical kinds of DBMS interfaces are as follows − Command-Line Interface (CLI) The earliest and most fundamental form of DBMS interface is the command-line interface (CLI). Through the use of a command ... Read More
A buffer is a memory location used by a database management system (DBMS) to temporarily hold data that has recently been accessed or updated in the database. This buffer, often referred to as a database buffer, acts as a link between the programs accessing the data and the physical storage devices. The database buffer is essential for enhancing the DBMS's overall performance. Caching frequently requested data in memory, it decreases the frequency of disc I/O operations, accelerating query and transaction processing. A more thorough explanation of a DBMS database buffer may be found in the following sections. Purpose of the ... Read More
