Concept explainers

SQL

SQL stands for Structured Query Language, is a form of communication that uses queries structured in a specific format to store, manage & retrieve data from a relational database.

Queries

A query is a type of computer programming language that is used to retrieve data from a database. Databases are useful in a variety of ways. They enable the retrieval of records or parts of records, as well as the performance of various calculations prior to displaying the results. A search query is one type of query that many people perform several times per day. A search query is executed every time you use a search engine to find something. When you press the Enter key, the keywords are sent to the search engine, where they are processed by an algorithm that retrieves related results from the search index. Your query's results are displayed on a search engine results page, or SER.

When you use a transaction, the database tables/views/other resources used in the transaction are locked until the transaction is either committed or rolled back in order to ensure all modifications are either ALL made, or none of them made. Usually databases also have options on the level of locking used such as no one can read or make changes to those resources when locked, or users can’t make changes to the resources but they can read data in the tables/views/read access to resources. Pick a potential problem with database locks on tables/views/resources and one popular way database administrators and / or database users use to address that problem?
