Answer:

columns, rows

Explanation:

In Computer programming, a atabase schema refers to the logical design of the database while the database instance refers to a snapshot of the data found in a database at a given instant in time.

Basically, in database management, the term "schema" is used to denote a representation of data while the term "instance" is used to denote an instance of time.

A database schema is a structure which is typically used to represent the logical design of the database and as such represents how data are stored or organized and the relationships existing in a database management system. There are two (2) main categories of a database schema; physical database schema and logical database schema.

Also, a database instance is a snapshot of the data in the database at a given instant in time and as such represents an operational database by following the conditions, validation and constraints set for a database management system.

These data can be stored or organized in a database management system through the use of multiple-column record formats.

In a multiple-column record of a data file, columns represent different variables and rows represent different cases (respondents) such as experimental data, independent observations etc.

Also, you can edit them quite easily as well. It's not that hard like the Lisp used to be in the past. And supermarket has a mix blend of the database. And modern databases like Data Lake can be very useful, undoubtedly.

You can store security type of requirements, like CCTV footage, each shop details like shop ID, Product list, shop type, electricity bill, hours of opening, floor, facilities, no. of employees, etc., and like this, we can have the details for the entire supermarket, and each shop there definitely.

<h3>What is SDLC?</h3>

SDLC is an abbreviation for system development life cycle and it can be defined as a strategic methodology that defines the key steps, phases, or stages for the design, development and implementation of high quality systems.

In Computer technology, there are seven (7) phases involved in the development of a system and these include the following;

  • Planning
  • Analysis
  • Design
  • Development (coding)
  • Testing
  • Deployment
  • Maintenance

Also, phased implementation simply refers to an implementation methodology in which smaller portions of functionality of a system are typically implemented one at a time (one after the other).

In conclusion, we can infer and logically deduce that you would acquire all the necessary hardware and software during the <u>design</u> phase of system development.
