Database Design Assignment Help
Help with Database Design Assignment
First we need to understand the meaning of database design. The process of creating the detailed data model of a database is known as Database Design. The data model for creating database design has two type of model namely logical and physical model. Therefore, DDL - Data Definition Language is generated by using all the logical, physical design choices and storage parameters from the logical data model. This DDL - Data Definition Language is used to produce a database. In Database Design, each entity is allocated with the set of attributes. We can understand database design in a very simple manner, proper management and Organization of data which follow by database models known as database design. The designer plays a crucial role while designing the database. And he determines what kinds of data must be stored and how data elements should interrelate. Once the designer is done with his research and requirement he will fit the data to the database model.
Database design consists of activities like classifying data and identifying interrelationship between the data. When we represent data in a theoretical manner is called an ontology. We use ontology for database design. Most of the time the person who a design database is a person who has expertise in the area of database design rather than expertise in the domain. The most important thing for designing database is requirement analysis. Without proper requirement analysis, it would be hard for any designer to design a database which will fulfil all the requirement of the users. For designing a database designer need to check the needed information from those who have domain knowledge. Because those who have domain knowledge most of the time fail to express clearly what the system wants. And what are the exact requirements for database designing?

The term Database design is a broad term which can be used to explain various parts of the database management assignments. The easiest definition of database design is - "to create the logical design of the data structures for storing data". In the relational database model, table and view are present. In an object database model, entities and relationships are mapped directly. Therefore, database design can be used to for each and every process of designing database.

Importance of Database design in real world applications
As we have seen the proliferation of data over the years it has become very important to have a robust database that can hold millions of entries. Most the business are data driven. If we talk about Facebook, it is all about data. Same goes for Google and Other marketing companies. Apart from holding the information data retrieval is one of the most important parts of databases. If we are not able to fetch data at an efficient rate, then the concept of databases is rendered useless. Hence, database design in one of the most important aspect of databases.
Steps in solving a database design homework
- Find out the purpose of Database - It would help you for all the leftover steps.
- Identify the Information Required to Store - Identify the information required to store in the database such as username, password, email, name, date of birth in case of registering user.
- Design Tables required for storing data - Identify the information which is related to an entity and make it a table such as User_account, user_profile.
- Design Columns in the table - Identify which set of data is to be stored in which table. Each item becomes a field and is displayed as a column in the table. For example, username, email, and password become columns of user_account, name and date_of_birth become columns of user_profile.
- Identify primary keys - Each row has to identified uniquely so assign a primary key to a field which would be unique. For example, userid is primary key for user_account table.
- Desing Relationship between Tables - Identify the columns which can be related to another column of the different table to maintain consistency. For example, user_account and user_profile table would be related with column user_id in both the tables.
- Review and Refine your design - After reviewing your database design, create the actual database and tables. Insert some data into the tables and check the correctness of the result fetched. If the result is not correct, redesign your database and recheck for the result.
- Apply the normalization rules - Apply Normalization in the database to make the database design robust.
Learn the subject and hire tutors for assignment writing

Database structures for the practical implementations. Moreover, professors might ask to implement any programming assignment that require intensive use of database concepts.
