The opening of Amazon Go has flooded the Moments. Customers will shop o n Amazon Go after downloading the Amazon Go App and connecting the ir debit card with the app . During shopping , a product will be shown on the Amazon Go App if chosen from the shelf, and will automatically be canceled if put back on the shelf. When you have selected your items and are ready to leave, the payment of the order will be automatically completed in the app . With benefits brought by the new science and technology of artificial intelligence, users’ behaviors can be accurately identified by a large number of cameras or even microphones, which is a great step for us to enter an intelligent life. Have you though t about the concepts and principles implied in artificial intelligence technology while you are expressing the great convenience that Amazon Go brings to life?

9.1 Computational Thinking Skills: Show an understanding of abstraction Need for and benefits of using abstraction Describe the purpose of abstraction Produce an abstract model of a system by only including essential details Describe and use decomposition Break down problems into sub-problems leading to the concept of a program module (procedure / function) 9.2 Algorithms: Show understanding that an algorithm is a solution to a problem expressed as a sequence of defined steps. Use suitable identifier names for the representation of data used by a problem and represent these using an identifier table Write pseudocode that contains input, process and output Write pseudocode using the three basic constructs of sequence, selection and iteration (repetition) Document a simple algorithm using pseudocode Write pseudocode from: a structured English description a flowchart Describe and use the process of stepwise refinement to express an algorithm to a level of detail from which the task may be programmed Use logic statements to define parts of an algorithm solution

DatabaseStructured Query Language (SQL) What is SQL? SQL stands for Structured Query Language SQL lets you access and manipulate databases What Can SQL do? SQL can execute queries against a database SQL can retrieve data from a database SQL can insert records in a database SQL can update records in a database SQL can delete records from a database SQL can create new databases SQL can create new tables in a database SQL can create stored procedures in a database SQL can create views in a database SQL can set permissions on tables, procedures, and views Using SQL in Your Web Site To build a web site that shows data from a database, you will need: An RDBMS database program (i.e. MS Access, SQL Server, MySQL) To use a server-side scripting language, like PHP or ASP To use SQL to get the data you want To use HTML / CSS to style the page **What is RDBMS? ** RDBMS stands for Relational Database Management System. RDBMS is the basis for SQL, and for all modern database systems such as MS SQL Server, IBM DB2, Oracle, MySQL, and Microsoft Access. The data in RDBMS is stored in database objects called tables. A table is a collection of related data entries and it consists of columns and rows.

***Data representation: ** 1.1.1 Binary systems •• recognise the use of binary numbers in computer systems •• convert positive denary integers into binary and positive binary integers into denary (a maximum of 16 bits will be used) •• show understanding of the concept of a byte and how the byte is used to measure memory size •• use binary in computer registers for a given application (such as in robotics, digital instruments and counting systems) 1.1.2 Hexadecimal •• represent positive numbers in hexadecimal notation •• show understanding of the reasons for choosing hexadecimal notation to represent numbers •• convert positive hexadecimal integers to and from denary (a maximum of four hexadecimal digits will be required) •• convert positive hexadecimal integers to and from binary (a maximum of 16 bit binary numbers will be required) •• represent numbers stored in registers and main memory as hexadecimal •• identify current uses of hexadecimal numbers in computing, such as defining colours in Hypertext Markup Language (HTML), Media Access Control (MAC) addresses, assembly languages and machine code, debugging 1.1.3 Data storage •• show understanding that sound (music), pictures, video, text and numbers are stored in different formats •• identify and describe methods of error detection and correction, such as parity checks, check digits, checksums and Automatic Repeat reQuests (ARQ) •• show understanding of the concept of Musical Instrument Digital Interface (MIDI) files, JPEG files, MP3 and MP4 files •• show understanding of the principles of data compression (lossless and lossy) applied to music/video, photos and text files
