All rights reserved. ǀ PUBLIC 4  \nDatabase Overview  \nWhat is Database?  \n• A book?  \n• A spreadsheet?  \n• A menu on the table in the restaurant?  \n• A Database is a collection of data that is related to a particular topic or purpose. As an example, employee records in a filing cabinet, a collection of sales leads ina notebook, are examples of collections of data or databases.  \n© 2017 SAP SE or an SAP affiliate company. All rights reserved. ǀ PUBLIC 6  \nWhy do we need Database?  \n• Do you find yourself entering the same values of information into multiple spreadsheets/reports/documents?  \n• When you make the changes in your spreadsheet/reports/documents, are you forced to make the same changes in others?  \n• Do you have a large amount of data that is becoming larger and unmanageable?  \n• Do several people in your organization have the need to view your data at the same time?  \n• When viewing your information, are you constantly scrolling on your screen to view it all? Or do you have a difficult time viewing the specific sets of data that you want?  \n© 2017 SAP SE or an SAP affiliate company. All rights reserved. ǀ PUBLIC 7  \nAdvantages of Database  \n• Data Independence/Reduced Maintenance  \n• Improved Data Sharing  \n• Increased Application Development Productivity  \n• Enforcement of Standards  \n• Improved Data Quality (Constraints)  \n• Better Data Accessibility/ Responsiveness  \n• Security, Backup/Recovery, Concurrency  \nSince database is that good, how to make a database?  \n© 2017 SAP SE or an SAP affiliate company. All rights reserved. ǀ PUBLIC 8  \nTables  \n• Using tables is the best way to store structured data.  \n• They consist of rows and columns.  \n• Columns possess headers defining the data type stored in them and the name with which the column can be addressed.  \n• Rows hold the actual attribute which are stored in the database.  \n• Each row is uniquely identified by a Primary Key that is represented by one or more columns.  \n• A Foreign Key points to a column or a set of column in another (referenced) table.  \n0  \n1 2  \n3 4  \nP F  \n\n| |  | |  |  |\n| --- | --- | --- | --- | --- |\n| |  | |  |  |\n| |  | |  |  |\n| |  | |  |  |\n| |  | |  |  |\n\n© 2017 SAP SE or an SAP affiliate company. All rights reserved. ǀ PUBLIC 9  \nTransactions and the ACID principle  \nA Transaction is an indivisible unit of processes such as reads and writes.  \nACID is an acronym for Atomicity, Consistency, Isolation and Durability.  \n• Atomicity: A Transaction fails even if only one part of it fails.  \n• Consistency: A Transaction brings the database from one consistent state to another.  \n• Isolation: Transactions cannot interfere with each other.  \n• Durability: Data changed by committed Transaction are persisted, even after a power loss or error.  \n© 2017 SAP SE or an SAP affiliate company.
