Advantages and Disadvantages of DBMS

This article will discuss the advantages and disadvantages associated with DBMS.

A database management system allows you to efficiently create, manage, and update databases. It also replaces the older file systems that were used to store and retrieve data. Although the DBMS allows users to manage large databases efficiently and with ease, it is important to understand the pros and cons of using it before you start to use it. Let's take a closer look at it.

Advantages and Disadvantages of DBMS


Benefits of DBMS

1.  Data Abstraction

This is a critical characteristic of any software system, and DBMS does a great job in this area. It conceals unnecessary details and only shows the information that is relevant to the user in order to complete his task. It reduces the complexity of hidden details and makes it easier to use.

2. Data Redundancy Control

Database Management System can also eliminate redundancy from the record system by efficiently using the ACID (Atomicity, Consistency, Isolation, and Durability), and normalization properties.

3. Minimizing data inconsistency

The Database Management System reduces redundancy and makes the system more consistent by eliminating all inconsistencies.

4. Data Manipulation is easy

To manipulate the information in the database, the DBMS uses SQL commands such as SELECT (to select records from one or several tables), INSERT and UPDATE (to update the records' information), DELETE (to remove one or more records from a particular table), to create database manipulation languages like SQL.

5.  Data Security

The Database Management System is different from the old file system. It comes with a secure login password that can be used for both admin and user access. Access can also be restricted to certain extents for changes and user access.

6. 

Multiple users can access the same database at once, which makes data sharing easy. The database is accessible from anywhere users want to be. Users do not need to limit their access to a specific location. They can use the database as they wish, according to their own preferences and the software and hardware requirements.

7. Improved Data Access

Data is organized in a way that makes it easy to access. It is possible to retrieve the data you need immediately without having to worry about duplicates or excess records. This saves time and is also very efficient.

8. Data Independence

Data stored in a database are completely independent of other data. You can search for the data you want without having to consider any other data.


Advantages of DBMS

1. Increased cost

A Database Management System requires a fast processor and large memory. This is why it's expensive hardware, and therefore expensive software.

We also need to spend a lot to convert our data to a Database Management System, which increases the cost of the Database Management System.

We need a well-trained and educated staff to use a Database Management System.

Database Management System is therefore a more expensive system.

2. Management Complexity

It is no easy task to manage the Database Management System once you have it installed. It is important to have competent staff who can manage the system. Sometimes it can be difficult to choose where to store data or where to retrieve it.

3. Maintenance costs

A Database Management System has a high maintenance price. This includes the cost of maintaining the Database Management System after it is created.

4. Frequency Upgrade/Replacement

Database Management System updates and upgrades are necessary to keep up with technological developments and market trends. These updates and changes can sometimes be so rapid that users have difficulty using the system. Administrators may also find it difficult to keep up with changes in the system (learn new commands and understand them each time an update is made).

DBMS is a broad area. Before we can work in this field, it is important to understand how it can help us. These points will give you a good idea of the prospect.

What is Modular Programming? Where is it used?

Image
 A module is a separate application component.  It may frequently be utilized in a number of functions and applications with different elements of this machine.  Similar functions are grouped into precisely the exact same component of programming language and separate functions are manufactured as separate units of code so the code could be reused by other programs.   Modular programming empowers multiple developers to split up the job and debug portions of this program independently.   Advances in programming impose logical boundaries between elements and enhance maintainability.  They're incorporated through ports.   Teams may create modules separately and don't need knowledge of all modules from the system. Each modular program has a version number associated with that.  This gives programmers flexibility in module upkeep.  If any changes must be implemented to a module, then just the affected subroutines need to be altered.  This makes the program much easier to read and co

What is Hibernate Framework?

Image
 What is Hibernate? Hibernate, an Object-Relational Mapping tool (ORM), reduces the complexity of application development. Hibernate framework that allows you to interact with data stored in databases. It uses specifications from the Java Persistence API, (JPA), and is licensed under the GNU Lesser General Public License. It supports nearly all relational databases. Gavin King is the father of hibernate. Hibernate is available in both Java SE (Standard Edition), and Java EE, Enterprise Edition. Hibernate (Enterprise Application Platform) is an integral part of JBoss EAP. JBoss tools allow for easy implementation and testing code during application development. What is the ORM tool? An Object-Relational Mapping tool is used to simplify the creation, manipulation and access of data. This technique maps the object to the database data. ORM can be used to resolve mismatches such as Granularity It can be further divided into new data fields. A person can be considered an entity, for examp

Ellipse command in AutoCAD

Image
  Ellipse command in AutoCAD Two focal points are encircled by a curve, which is known as the Ellipse. Two of the ellipse's axes, which specify its length and breadth, determine its form. The Ellipse command on the AutoCAD display allows you to construct ellipses in general. By putting the start and end points on two different axes, we may make an ellipse. Depending on the specification, the first and second axes of the ellipse might be classified as either minor or major axes. The icon of Ellipse will look like the below image: Move the pointer of your mouse on the Ellipse icon to view the dialogue box for Ellipse in AutoCAD. It will look like the given image: It consists of the drop-down list, which includes other options such as Elliptical Arc, Center, and Axis . The list will look like the given image: Let's discuss each type of Ellipse in detail. CENTRE In this procedure, the length determines the second axis while the centre point and terminus defin
