How Does Database Management System (DBMS) Work?
A database management system gives users access to stored data. It lets users add new data, change existing ones, and/or delete old or obsolete data. It also ensures the access of specific information to authorized users only. To enable this, a DBMS needs to be structured in a way that lets users extract only particular types of information. This is regulated through a specific criterion.
For example, if a user wants all accounts related to customers in New Jersey, they just need to enter “New Jersey” into the search tab. They can then return all corresponding records from this table. When the database has been arranged as per the business’s needs, developers can build apps around it.
Primary Concepts of DBMS
There are various concepts in DBMS. These include the following:
1. Data Models
It is the abstract presentation of a database system. These models are employed to build and implement a database. They are designed through conceptual modeling. They also function to define the organization and structure of how data is stored physically.
2. Query Languages
Query languages let users find and manipulate data in databases. The most common among these languages is SQL or structured query languages. Besides, there are other languages like data definition language, data manipulation language, data query language, and data control language. Every language has its own syntax. However, all share a single premise of letting you extract data from a database view or table. It also lets you change data or add new information.
3. Database File Organization and Indexing
File organization facilitates optimal utilization of storage space in a database. It also lets users retrieve data they want quickly. Index files and data files are two levels of database files. Index files have indexing structures defining data locations for quicker retrieval. Users use these files to find particular records in a table structure.
Data files contain variable length and fixed length records.
Normalization gets rid of duplicate data. This process consists of breaking down related tables into several tables according to business rules. Breaking up associated tables into various entities lets you store data efficiently. Normalization eliminates redundancy and problems like database corruption.
5. Candidate Key
The candidate key defines the relationship between tables. It must be present in each table. It consists of unique attributes and static values.
6. Key Fields
A key field acts as a unique identifier for every row in a table. A table has only one key field. The primary key should be unique in different views and tables. The primary key’s value automatically increments by one with the addition of a new record to the table.
