NoSQL databases, which stand for "not only SQL, " are a popular alternative to traditional relational databases. They are designed to handle large amounts of unstructured or semi-structured data, and are often used for big data and real-time web applications. However, like any technology, NoSQL databases come with their own set of challenges. Challenges of NoSQL Data modeling and schema design One of the biggest challenges with NoSQL databases is data modeling and schema design. Unlike relational databases, which have a well-defined schema and a fixed set of tables, NoSQL databases often do not have a fixed schema. This can ... Read More

Updated on 16-Jan-2023 16:16:06
Introduction A database management system (DBMS) is a software system that is designed to manage and organize data in a structured manner. In order to accomplish this, DBMS uses a specific architecture that dictates how data is stored, retrieved, and updated. Two of the most commonly used architectures in DBMS are centralized and client-server architectures. Centralized Architecture A centralized architecture for DBMS is one in which all data is stored on a single server, and all clients connect to that server in order to access and manipulate the data. This type of architecture is also known as a monolithic architecture. ... Read More

Bitmap indexing in DBMS is a type of indexing technique that is used to improve the performance of database systems. It works by creating a bitmap for each distinct value in a database column, with each bit in the bitmap representing a row in the database table. The bitmap index can then be used to quickly identify which rows in the table match a given search criteria, making it an efficient way to filter and retrieve data from large tables. In this article, we will delve into the concept of bitmap indexing and how it works, the advantages and disadvantages ... Read More
