Important Terms Related to Database Management System

When it comes to database management, there are a few key concepts that you need to understand. In this blog post, we will be discussing three of the most important terms: Data Manipulation Languages (DML), Structured Query Language (SQL), and Data Definition Language (DDL). We will be explaining what each of these terms means and how they are used in database management. Stay tuned for more information on this topic!

What is database management?

A database management system (DBMS) is a software application that enables users to create and manage databases. A DBMS can be used to store data for a variety of purposes, including websites, customer information, and inventory tracking.

There are many different types of DBMSs available, but the most common is the SQL database. SQL is a standard data manipulation language that enables users to create, read, update, and delete (CRUD) data from a database.

SQL is the most popular DBMS because it is easy to use and provides a high level of security.

Terms Related to Database Management System:

Here is the list of terms that you need to know about if you are interested in pursuing a career in database management systems:

– Data Manipulation Language (DML): This is the language used to interact with the data in the database. It includes commands to insert, update, and delete data.

– Structured Query Language (SQL): This is the standard language for querying databases. It is a powerful language that can be used to perform complex queries.

– Data Definition Language (DDL): This language is used to create and modify the structure of the database. It includes commands to create, delete, and alter tables and other database objects.

– Database: This is a collection of data that is organized in a specific way. A database can be divided into tables, which are then further divided into fields and records.

– Table: This is the basic unit of data in a database. A table consists of a number of fields, each of which contains a specific type of data.

– Field: This is the name given to a particular column in a table. A field can contain any type of data, including text, numbers, and dates.

– Record: This is the individual unit of data in a table. A record consists of a number of fields, each of which contains a specific type of data.

– Column: This is the name given to a particular field in a table. A column can contain any type of data, including text, numbers, and dates.

– Row: This is the name given to a particular record in a table. A row consists of a number of fields, each of which contains a specific type of data.

-RDBMS: This is the acronym for “relational database management system.” A RDBMS is a type of database that stores data in tables. It is the most popular type of database system.

-Database Administrator (DBA): This is the person responsible for managing a database. The DBA is responsible for creating and modifying the structure of the database, adding new data, and ensuring that the database is running correctly.

-Database Designer: This is the person responsible for designing the structure of a database. The database designer is responsible for creating the tables, fields, and records that will be used in the database.

-Database Developer: This is the person responsible for developing applications that use a database. The database developer is responsible for creating the code that will allow the application to interact with the database.

-Cascade: This is a term that is used when deleting data from a table. When you delete data from a table, the system will automatically delete the data from all of the tables that are related to it. This is known as a cascade delete.

-Referential Integrity: This is a term that is used to describe the relationship between two tables. When you create a table, you can specify that it should be related to another table. This means that the data in the two tables will be linked together. When you delete a record from one table, the system will automatically delete the corresponding record from the other table. This is known as referential integrity.

-Primary Key: This is the name given to the column in a table that is used to identify the records in the table. The primary key is a unique column, meaning that no two records in the table can have the same value in the primary key column.

-Foreign Key: This is the name given to the column in a table that is used to identify the records in another table. The foreign key is a column in a table that references the primary key of another table. This means that the data in the two tables will be linked together. When you delete a record from one table, the system will automatically delete the corresponding record from the other table. This is known as referential integrity.

These are the basic terms that you need to know about database management systems. 

Conclusion:

There are many other terms and concepts that you will learn as you delve further into the world of database management systems, but these are some of the most important ones to know. By understanding these terms and concepts, you will be able to effectively manage and use databases for your own purposes. So, what are you waiting for?
