B) Copy-paste
C) File compression
D) SQL injections

Answer 1

Data stored in separate tables can be reconstructed through the use of SELECT statements in SQL.

Step-by-step explanation:

Data stored in separate tables can be reconstructed through the use of SELECT statements in SQL. SELECT statements allow you to retrieve data from one or more tables by specifying the columns and conditions you want to filter on. By writing a SELECT statement, you can combine data from different tables and obtain a result that represents the reconstructed data. Data stored in separate tables can be reconstructed through the use of SELECT statements. This is a function of Structured Query Language (SQL), which is the language used for managing and manipulating databases. SELECT statements allow you to query the database and retrieve the desired data from one or more tables. This can include joining tables, where data from different tables are combined based on a related column between them, such as a primary key-foreign key relationship. For instance, if you have a customers table and an orders table, you can join them on a customer ID to view all orders for each customer. This is different from copy-pasting, file compression, or SQL injections, which have different purposes and are not standard methods for reconstructing data from separate tables in a database.
