While TKIP is useful for upgrading security on devices originally equipped with WEP, it does not address all of the security issues facing WLANs and may not be reliable or efficient enough for sensitive corporate and government data transmission. The standard specifies the Advanced Encryption Standard ( AES ) in addition to TKIP. AES offers a higher level of security and is approved for government use, but requires a hardware upgrade for implementation. As organizations replace older wireless equipment, AES is expected to become the accepted encryption standard for WLAN security.
The primary key of a database table is a unique identifier assigned to each record. Each table will have one or more columns designated as the primary key. A Social Security number can be a primary key for a database listing of employees because each Social Security number is unique. However, because of privacy concerns, an assigned company ID number is a better choice to function as a primary key for employees. Some database software—such as Microsoft Access—assigns the primary key automatically, but the random key has no real meaning. It is better to use a key with meaning to the record. The simplest way to enforce referential integrity is not to allow changes to a primary key.
Another use of the term, "integrity" appears in the work of Michael Jensen and Werner Erhard in their academic paper, "Integrity: A Positive Model that Incorporates the Normative Phenomenon of Morality, Ethics, and Legality". In this paper the authors explore a new model of integrity as the state of being whole and complete, unbroken, unimpaired, sound, and in perfect condition. They posit a new model of integrity that provides access to increased performance for individuals, groups, organizations, and societies. Their model "reveals the causal link between integrity and increased performance, quality of life, and value-creation for all entities, and provides access to that causal link."    According to Muel Kaptein, integrity is not a one-dimensional concept. In his book he presents a multifaceted perspective of integrity. Integrity relates to, for example, compliance to the rules as well as to social expectations, with morality as well as ethics, and with actions as well as attitude.
