Book of Isaiah

The Book of Isaiah (Hebrew: ספר ישעיהו‎, IPA: [sɛ.fɛr jə.ʃaʕ.ˈjɑː.hu]) is the first of the Latter Prophets in the Hebrew Bible and the first of the Major Prophets in English Bibles. The book is identified by a superscription as the works of the 8th-century BCE prophet Isaiah ben Amoz, but there is ample evidence that much of it was composed during the Babylonian captivity and later.Bernhard Duhm originated the view, held as a consensus through most of the 20th century, that the book comprises three separate collections of oracles:Proto-Isaiah (chapters 1–39), containing the words of Isaiah; Deutero-Isaiah (chapters 40–55), the work of an anonymous 6th-century author writing during the Exile; and Trito-Isaiah (chapters 56–66), composed after the return from Exile. While virtually no one today attributes the entire book, or even most of it, to one person, the book's essential unity has become a focus in current research. Isaiah 1–33 promises judgment and restoration for Judah, Jerusalem and the nations, and chapters 34–66 presume that judgment has been pronounced and restoration follows soon. It can thus be read as an extended meditation on the destiny of Jerusalem into and after the Exile.

Is-a

In knowledge representation, object-oriented programming and design (see object oriented program architecture), is-a (is_a or is a) is a subsumption relationship between abstractions (e.g. types, classes), where one class A is a subclass of another class B (and so B is a superclass of A). In other words, type A is a subtype of type B when A’s specification implies B’s specification. That is, any object (or class) that satisfies A’s specification also satisfies B’s specification, because B’s specification is weaker.

The is-a relationship is to be contrasted with the has-a (has_a or has a) relationship between types (classes).

It may also be contrasted with the instance-of relationship between objects (instances) and types (classes): see "type-token distinction" and "type-token relations." When designing a model (e.g., a computer program) of the real-world relationship between an object and its subordinate, a common error is confusing the relations has-a and is-a.

To summarize the relations, we have

Windows code page

Windows code pages are sets of characters or code pages (known as character encodings in other operating systems) used in Microsoft Windows from the 1980s and 1990s. Windows code pages were gradually superseded when Unicode was implemented in Windows, although they are still supported both within Windows and other platforms.

There are two groups of code pages in Windows systems: OEM and ANSI code pages. Code pages in both of these groups are extended ASCII code pages.

ANSI code page

ANSI code pages (officially called "Windows code pages" after Microsoft accepted the former term being a misnomer) are used for native non-Unicode (say, byte oriented) applications using a graphical user interface on Windows systems. ANSI Windows code pages, and especially the code page 1252, were called that way since they were purportedly based on drafts submitted or intended for ANSI. However, ANSI and ISO have not standardized any of these code pages. Instead they are either supersets of the standard sets such as those of ISO 8859 and the various national standards (like Windows-1252 vs. ISO-8859-1), major modifications of these (making them incompatible to various degrees, like Windows-1250 vs. ISO-8859-2) or having no parallel encoding (like Windows-1257 vs. ISO-8859-4; ISO-8859-13 was introduced much later). About twelve of the typography and business characters from CP1252 at code points 0x80–0x9F (in ISO 8859 occupied by C1 control codes, which are useless in Windows) are present in many other ANSI/Windows code pages at the same codes. These code pages are labelled by Internet Assigned Numbers Authority (IANA) as "Windows-number".

SQL-92

SQL-92 was the third revision of the SQL database query language. Unlike SQL-89, it was a major revision of the standard. For all but a few minor incompatibilities, the SQL-89 standard is forward compatible with SQL-92.

The standard specification itself grew about five times compared to SQL-89. Much of it was due more precise specifications of existing features; the increase due to new features was only by a factor of 1.5–2. Many of the new features had already been implemented by vendors before the new standard was adopted. However, most of the new features were added to the "intermediate" and "full" tiers of the specification, meaning that conformance with SQL-92 entry level was scarcely any more demanding than conformance with SQL-89.

Later revisions of the standard include SQL:1999 (SQL3), SQL:2003, SQL:2008, and SQL:2011.

New features
