Creating a database:
➢We use this software to organize and manipulate data in practice.
CREATE DATABSE [IF NOT EXISTS] database_name;
➢We use the data definition language CREATE statement to create
a database.
➢The command we need in this case is CREATE DATABASE. The
syntax to abide by is CREATE DATABASE.
➢[IF NOT EXISTS] is the optional statement.
➢The name of the database
➢And finally, a semicolon (;).

CREATE DATABASE:
➢ It will obviously create a database as an abstract unit.
➢ This means that for the moment the database will not contain any
data and will simply represent an object ready to be filled with
information.
[IF NOT EXISTS]:
➢It will verify if a database with same name exists already if it does,
this will impede us from creating a database with the same name.

- 5. ➢ Brackets around indicate that the statement in between them is optional in the syntax. ➢You could either type or omit the statement. Even if you don’t include it code will run anyway. ➢Neverthless, always using it allows you to avoid potential errors when working with large amount of data. database_name : ➢Give a name that is short but at the same time as related to the content of the data as possible. ➢Whether you use uppercase or lowercase letters only, or both. 10/18/2022 www.clinosol.com | follow us on social media @clinosolresearch 5
- 6. ➢ while writing the name of the database quotes are optional. Suppose the database name is trails, you could either say “trails” with quotes or without using quotes. It makes no difference. • trails • TRAILS • Trails • “trails” Semicolon: ➢ Finally, you should always end your statements with the semicolon character (;) ➢ It indicates that the statement is terminated. 10/18/2022 www.clinosol.com | follow us on social media @clinosolresearch 6

- 8. DATABASE MANAGEMENT SYSTEM • A database management system is a computerized data keeping system. • Users of the system are given facilities to perform several kinds of operations on such a system for either manipulation of the data in the database or management of the database structure itself. 8 www.clinosol.com | follow us on social media @clinosolresearch 10/18/2022
- 9. What database management system should you choose? The perfect DBMS depends on several factors, ● Purpose of the database: Different DBMS are optimized for different purposes. For example, DBMSs are designed for transactions processing, while others are designed for data warehousing. ● The scale of the database: The size of the database, number of users, and the amount of data that will be stored all impact the choice of DBMS ● Performance requirements: The response time and transactions will also affect the choice of DBMS. ● Cost: Different DBMS have different licensing fees and hardware requirements. 10/18/2022 www.clinosol.com | follow us on social media @clinosolresearch 9
- 10. Based on the above mentioned factors, some popular DBMS for database development include following, ● MY SQL: a widely used open-source relational database management system. ● Postgre SQL: a powerful open-source object-relational database management system. ● Microsoft SQL server: a popular commercial relational database management system. ● Oracle database: a powerful and widely used commercial relational database management system. 10/18/2022 www.clinosol.com | follow us on social media @clinosolresearch 10
- 11. ● Microsoft access: an older DBMS and prone to something called “bloating”, but it is great for beginners. The user interface is second to none for building your relational database, forms, and queries. ● MongoDB: a document-oriented NoSQL database management system known for its scalability and ease of use. 10/18/2022 www.clinosol.com | follow us on social media @clinosolresearch 11
- 12. ● The best choice will depend on the size and complexity of your database, the type of data you need to store, performance requirements, and budget. CONCLUSION Databases are used to store, organize and manipulate the data by using database management systems. 10/18/2022 www.clinosol.com | follow us on social media @clinosolresearch 12
