Public campaign for Urdu TTS, please support us!

As you know, the Urdu is one of the biggest language of the world, but still there is no efficient  Text-to-speech engine available for any platform. There are many languages in the field of TTS, those are covered by many famous companies who are running their TTS solutions in the market. But none of them is paying attention towards Urdu language.

So in the first step, we are requesting Google to add Urdu language in their android's text-to-speech engine called "google TTS". For this purpose, we have started a petition on Change.org. This petition required supporters as much as possible, from all over the world to build a strongest impression. So we would like that you, as the BHP lover, sign this petition by visiting the following link. If you are not the Urdu speaker, even then sign this patition just for the sake of social cause, and for helping your visually impaired community. Don't worry, they will not ask any private information - you will just need to enter your e-mail and comment while signing the petition. Also copy the link from the address bar after visiting that page, and share in your circle, and ask your contacts to contribute towards this campaign. You can also directly share the petition to the various social media networks from that page as well.

So, Let's do it now and here!:

Introduction to Database Management System (DBMS)

What Is The Database Management System (DBMS)?

A database management system (DBMS) is system software for creating and managing databases. The DBMS provides users and programmers with a systematic way to create, retrieve, update and manage data.

A DBMS makes it possible for end users to create, read, update and delete data in a database. The DBMS essentially serves as an interface between the database and end users or application programs, ensuring that data is consistently organized and remains easily accessible. The DBMS manages three important thing which are the data, the database engine that allows data to be accessed, locked and modified  and the database schema, which defines the database’s logical structure. These three foundation elements help provide concurrency, security, data integrity and uniform administration procedures. Typical database administration tasks supported by the DBMS include change management, performance monitoring/tuning and backup and recovery.

Many database management systems are also responsible for automated rollbacks,restarts and recovery as well as the logging and auditing of activity. The DBMS is perhaps most useful for providing a centralized view of data that can be accessed by multiple users, from multiple locations, in a controlled manner. A DBMS can limit what data the end user sees, as well as how that end user can view the data, providing many views of a single database schema. End users and software programs are free from having to understand where the data is physically located or on what type of storage media it resides because the DBMS handles all requests.

The DBMS can offer both logical and physical data independence. That means it can protect users and applications from needing to know where data is stored or having to be concerned about changes to the physical structure of data (storage and hardware). As long as programs use the application programming interface (API)for the database that is provided by the DBMS, developers won't have to modify programs just because changes have been made to the database.

With relational DBMSs (RDBMSs),this API is Structured Query Language (SQL) a standard programming language for defining, protecting and accessing data in a RDBMS.

 

Popular types of DBMS

Popular database models and their management systems include:

  • Relational database management system (RDMS)  - adaptable to most use cases, but RDBMS Tier-1 products can be quite expensive.
  • NoSQL DBMS is well-suited for loosely defined data structures that may evolve over time. 
  • In-memory database management system (IMDBMS) provides faster response times and better performance.
  • Columnar database management system (CDBMS) - well-suited for data warehouses that have a large number of similar data items.
  • Cloud-based data management system - the cloud service provider is responsible for providing and maintaining the DBMS.
