Understanding RDBMS: CRUD Functions, Create Relationships With Data, Prevent Duplication

JSMedia – In today’s modern era, maybe many people need to understand the term database to meet their needs. The term database will relate to various aspects of human life, so that it can affect all fields, one of which is understanding of RDBMS.

The relationship will also make some tables become part of the components in storing and creating data. This will affect an object, then the table will be connected to each other, so you must understand the key of the database as explained below.

Understanding RDBMS

Understanding RDBMS

1. Understanding RDBMS in General

Many people already know the rational model, in the sense that a database is built on a number of tables. This will relate to the columns and rows that are complemented by data or content.

However, to create a database it is necessary to integrate several aspects of a table concept with other tables. This key will relate to several aspects that are owned and developed. This is called an RDBMS.

RDBMS stands for Relational Database Management System, which means a relationship that will link the database in the management and management of a system. The key or relation is needed by every database.

2. RDBMS According to the Concept

RDBMS or Relational Database Management System is a conceptual system and has support between the relationships between tables in one database. Each of these tables has a focal point or key commonly known as a primary key.

The primary key has a function to connect the table to the next section, so that the database has a foreign key. This concept can usually be the basis for Compiling or creating a database in the company.

3. RDBMS by Function

The definition of RDBMS has actually been widely used by various vendors since 1970. This is also related to the development of understanding of RDBMS itself, so that many companies use a database with a hierarchical model.

There are also those who use the network who switch to the RDBMS model, this is because the RDBMS model has functions that are easy to use by large companies. However, today there are many types of databases that use the RDBMS concept.

An example of an RDBMS can be seen in the use of Ms. Access, MySQL, Oracle, SQL server, OpenOffice, PostgreSQL, and FoxBase. However, everything will return to the interests and functions used by the company.

Functions of RDBMS

Functions of RDBMS

The basic function of an RDBMS is to reference data storage in terms that are structured by tables, and use rows, and columns. The system itself refers to the database that keeps the data safe and consistent, other functions are as follows:

1. CRUD Function

Another basic RDBMS function is to deal with the number of tables in the database being compiled. You can read the data, and update the database structure. This will relate to the Create, Read, Update, and Delete (CRUD) functions.

2. Creating Relationships with Data

In the preparation of the database, RDBMS usually has a data dictionary and metadata features that can be used to process and handle information data. This feature is what makes RDBMS have the function to create relationships between data and tables.

It serves to create well-defined data. The relationship with the data can occur because of the assignment of certain keys, so it is called the primary key for the first part of the table that can be linked to others.

3. Prevent Duplication

Many people complain because there is a lot of data that is double and duplicated. This complicates the data being processed, thus making many people feel more tired in processing the database, and a waste of time.

This can be prevented by the RDBMS function as a deterrent to duplication of data. Repeatedly available data can be detected quickly, and you won’t get a complex database.

Data duplication can occur in any database, so you can use an RDBMS system to make it the main solution.

Understanding RDBMS and its functions can certainly make database creation easier and faster. You can use it to process data in large companies, so that company performance is well maintained and safe with a modern touch.
