Other data models include entity-relationship, record base, object-oriented, object relation, semi-structured, associative, context, and flat data models. Database system architecture in DBMS is categorized as either single tier, in which the DBMS is the only entity where the user directly sits on the DBMS and uses it, or multi-tier, in which nearly all components are independent and can be changed independently. A distributed database is a collection of related data in multiple interconnected databases that are logically interrelated, but physically stored across multiple physical locations.
Distributed databases are categorized as either homogeneous, in which all the physical locations use the same hardware and run the same operating systems and applications, or heterogeneous, in which each location may have different data, software, and hardware structures. A distributed database management system DDBMS refers to a centralized application that functions to create and manipulate distributed databases, synchronize the database at regular intervals and provide transparent access mechanisms to the user, ensure universal application of data modifications, maintain data security and integrity of the database, can be accessed by several users simultaneously, and is used in applications that process large volumes of data.
A traditional filing system refers to early endeavors to computerize the manual filing system. File-based systems typically use storage devices such as a CD-ROM or hard disk to store and organize computer files and the data within with the goal of facilitating easy access. A traditional file system is inexpensive, ideal for a small system with smaller quantity of parts, very low design efforts, isolated data, and has a simple backup system, but is not secure, has a lack of flexibility and many limitations, and has integrity flaws.
The people who are involved in such an environment are programmers, system administrators, and end-users. In the database environment, there are five components: data, hardware, software, people, and procedures. Multiple users can have quick access to the data and share it with other users without going through extra effort.
The system helps in searching the required information from a large database in just a few seconds. Therefore, it is highly effective for businesses to manage various types of data such as student records, employee information, inventory, payroll, project management, etc.
In the absence of database management systems, the data collection and storing tasks were conducted manually and it was a time-consuming process.
However, after the invention of the management system, users can access and work on data by a single click. For instance, in a sales organization, managers can identify high-performing employees by tracking their personnel files and sales performance file. Manufacturing It is used for the management of supply chain and for tracking production of items. Inventories status in warehouses. HR Management For information about employees, salaries, payroll, deduction, generation of paychecks, etc.
