Applying any form of data validation; failed validation may result in a full rejection of the data, partial rejection, or no rejection at all, and thus none, some, or all of the data is handed over to the next step depending on the rule design and exception handling; many of the above transformations may result in exceptions, e.g., when a code ...
SQL Injection is a common security vulnerability that arises from predominantly poor (or missing) input validation. Given that arbitrary SQL code can be supplied, it is can be devastating. SQL Code can be constructed to extract all information from the target system, alter information, destroy information, and under the right circumstances even ...
Stored procedure. A stored procedure (also termed prc, proc, storp, sproc, StoPro, StoredProc, StoreProc, sp, or SP) is a subroutine available to applications that access a relational database management system (RDBMS). Such procedures are stored in the database data dictionary . Uses for stored procedures include data-validation (integrated ...
View (SQL) In a database, a view is the result set of a stored query, which can be queried in the same manner as a persistent database collection object. [1] This pre-established query command is kept in the data dictionary. Unlike ordinary base tables in a relational database, a view does not form part of the physical schema: as a result set ...
DELETE. In HTTP, the GET (read), PUT (create and update), POST (create - if we don't have `id` or `uuid`), and DELETE (delete) methods are CRUD operations as they have storage management semantics, meaning that they let user agents directly manipulate the states of target resources. [3] The POST method, on the other hand, is a process operation ...
Overview. Data validation is intended to provide certain well-defined guarantees for fitness and consistency of data in an application or automated system. Data validation rules can be defined and designed using various methodologies, and be deployed in various contexts. [1] Their implementation can use declarative data integrity rules, or ...
Dynamic web page: example of server-side scripting (PHP and MySQL). A dynamic web page is a web page constructed at runtime (during software execution), as opposed to a static web page, delivered as it is stored. A server-side dynamic web page is a web page whose construction is controlled by an application server processing server-side scripts.
ACID. In computer science, ACID ( atomicity, consistency, isolation, durability) is a set of properties of database transactions intended to guarantee data validity despite errors, power failures, and other mishaps. [1] In the context of databases, a sequence of database operations that satisfies the ACID properties (which can be perceived as a ...
