Database Design Course Overview

Database refers to an organised collection of data curated to negate inconsistencies and make data management easier. For example, a collection of information such as marks of different subjects for some students might be challenging to deal with if not for data collection to manage comprehensively. A large amount of data requires several databases, which often grow into an unmanageable amount as well. This is where DBMS assists the database in managing containing information.

The database uses DBMS or database management system, and most prominently RDBMS, a relational database management system to maintain neat databases. RDBMS secures the database using tables and also contains the relationship between containing data. The system helps evaluate data to manage, modify, and regulate it per the user’s requirements. These systems use the SQL language to manage databases.

Database production follows a detailed process which requires the management system to follow a set pattern to design data tables, its storing process, regulation and implementation for the stored data. This process is known as database designing. A database design consists of detailed operations to design, develop, test, implement and maintain created database models for a reliable database system. Consistency in databases is crucial to comprehending the relation between containing data and their usefulness.

But why database design is important?

Database design under the RDBM system extends diverse benefits to users. Here’s why database designing is important.

  • Database designing works as a blueprint for data storage, defining how data would be saved in the modelled system. This will enable programmers to assess the influence of a database on an application’s performance.
  • Database design evaluates whether the model meets user requirements or not.
  • Database designing operations allow users to assess application behaviour and how data requests will be processed in the future.
  • Database design, working as a blueprint, would enable designers to work on constraining points and resolve the relevant points for higher efficiency.

Developers work on creating database design with the vision to deliver robust databases capable of delivering identified objectives without hindering application efficiency. To do so, certain steps are required to be followed. Database designers work on several steps using database management systems to create reliable databases.
process of database designing

Let us look at these steps that accomplish the process of database designing.

1. Identifying objectives and purposes of the database: The data design process starts with defining the objective of the database. Deriving the purpose beforehand helps developers prepare a plan following its scope and provides a direction to the process.

2.Searching and organising relevant information for the database: Collect the required information to be compiled. For example, figures such as a product’s information, order number and other relevant details.

3. Separating information using tables: Divide the information into major subjects such as product name and order name, creating a separate table for each.

4.Identify the information and divide it into columns: The user must identify which information must be included in every table. Every added information gets displayed as a column within the table after turning into a unique field. For example, a student’s table might contain columns such as marks and subjects.

5.Specify the primary key for each table: Specify the primary key for each table, which is a column or a group of many columns used to identify every unique row. An apt example would be the marks obtained by students.

6. Establish the relationship between each table: Identify interrelationships in each table through analysis and fill additional fields or new tables to refine the relationship if necessary.

7.Implement normalisation rules: Data normalisation rules are essential to check the quality of table structure. Make changes if you find any inconsistencies.

8. Use DBMS to build the database: Follow the derived blueprint and implement the model using a database management system to design the database.

9. Reassess for quality check: Assess the created design for any constraints or errors. Run several tests on the tables to evaluate their efficiency and reduce redundancy and inconsistencies.

Database management system requires users to practice specialised database languages explicitly created to access database management systems. Standard Query Language (SQL) is a domain-specific language that works with RDBMS to access, store, manage, manipulate, and maintain databases. The standard database language follows a set pattern of grammar and syntaxes to communicate with relational databases to work with query data.

Although a standard language, various relational database management systems create their unique subset of SQL to interact with databases and regulate their content. SQL is a predominant query language most commonly paired with the relational database management system called MySQL. Let’s learn more about MySQL to understand how the pair helps create robust databases

Initially created in 1995 for personal use, MySQL worked as a backbone for many organisations, managing its database system to ensure an easy flow of operations. MySQL is a free, open-source relational database management system which works with the standard version of the famous SQL language to support enormous databases. MySQL helps design, develop and implement database tables following interrelationships within containing information. The program implements a relational database in the computer by interacting with the operating system to regulate user access to databases and facilitate various tasks like testing database integrity.

Several features add to its success, being one of the top relational database management systems available in the market.

  • MySQL is free, easy to use, and works with most operating systems.
  • MySQL’s open-source license enables programmers to access the functionality of the most expensive and robust database packages.
  • Besides SQL, MySQL works with languages such as PHP, JAVA, C, C++, etc.
  • MySQL is comparatively faster than other RDBMSs with the ability to regulate huge data mounds, enabling up to 50 million rows in a single table and more
