Oracle Database is a proprietary multi-model database management system produced and marketed by Oracle Corporation. It is a database used for running online transaction processing, data warehousing and mixed database workloads; the latest generation, Oracle Database 19c, is available on-prem, on-cloud, or in a hybrid-Cloud environment. 19c may be deployed on Oracle Engineered Systems on-prem, on Oracle cloud or cloud at customer. At Openworld 2017 in San Francisco, Executive Chairman of the Board and CTO, Larry Ellison announced the next database generation, Oracle Autonomous Database. Larry Ellison and his two friends and former co-workers, Bob Miner and Ed Oates, started a consultancy called Software Development Laboratories in 1977. SDL developed the original version of the Oracle software; the name Oracle comes from the code-name of a CIA-funded project Ellison had worked on while employed by Ampex. Oracle products follow a custom - naming convention; the "c" in the current release, Oracle Database 19c, stands for "Cloud".
Previous releases have used suffixes of "g" and "i" which stand for "Grid" and "Internet" respectively. Prior to the release of Oracle8i Database, no suffixes featured in Oracle Database naming conventions. Note that there was no v1 of Oracle Database, as Larry Ellison, "knew no one would want to buy version 1". Oracle's RDBMS release numbering has used the following codes: The Oracle Database Administrators Guide includes a brief history on some of the key innovations introduced with each major release of Oracle Database. Oracle Corporation releases Critical Patch Updates or Security Patch Updates and Security Alerts to close security vulnerabilities. A 2016 Gartner report claimed to show Oracle holding #1 RDBMS market share worldwide based on the revenue share ahead of its four closest competitors – Microsoft, IBM, SAP and Teradata. In the market for relational databases, Oracle Database competes against commercial products such as IBM's DB2 UDB and Microsoft SQL Server. Oracle and IBM tend to battle for the mid-range database market on Unix and Linux platforms, while Microsoft dominates the mid-range database market on Microsoft Windows platforms.
However, since they share many of the same customers, Oracle and IBM tend to support each other's products in many middleware and application categories, IBM's hardware divisions work with Oracle on performance-optimizing server-technologies. Niche commercial competitors include Teradata, Software AG's ADABAS, IBM's Informix, among many others; the Oracle database products compete against such open-source software relational and non-relational database systems as PostgreSQL, MongoDB, Neo4j and others. Oracle acquired Innobase, supplier of the InnoDB codebase to MySQL, in part to compete better against open source alternatives, acquired Sun Microsystems, owner of MySQL, in 2010. Database products licensed as open-source are, by the legal terms of the Open Source Definition, free to distribute and free of royalty or other licensing fees.

John Souttar is a Scottish professional footballer who plays for Heart of Midlothian in the Scottish Premiership, for the Scotland national team. He played for Dundee United before joining Hearts in February 2016; as of January 2020, he is vice-captain of Hearts. Known as a central defender, Souttar was converted to play as a defensive midfielder towards the end of his stay at Dundee United, however he has more been deployed as a centre back for Hearts, he is the youngest player to have appeared for Dundee United's first team, having made his debut for the club in January 2013 at the age of 16. After representing the country at under-17, under-19 and under-21 levels, he made his full international debut in September 2018. Souttar was born in Aberdeen on 25 September 1996 to parents Heather, his father had been a professional footballer, with Brechin City. His mother's side of the family hails from Australia. Growing up in the village of Luthermuir, Souttar attended Luthermuir Primary and Mearns Academy in nearby Laurencekirk.
In 2002, Souttar began to play for Brechin City Boys Club, where he was coached by his father in a successful team containing Ryan Gauld and Euan Spark. The trio developed their skills at coaching schools run in Dundee by Ian Cathro, before joining Dundee United's youth system in 2006 at the age of nine. Souttar has a younger brother, who plays for Stoke City. After progressing through the various youth team levels at Dundee United, Souttar signed a professional contract in July 2012 and became a member of the club's under-20 development squad. After just four months in the development team and suspensions led to Souttar making his first team debut on 2 January 2013, playing in central defence from the start in a 2–2 draw with Aberdeen at Pittodrie Stadium. Aged 16 years and 99 days, he became the youngest player to play for Dundee United. On 24 January 2013, Souttar signed a contract extension keeping him at the club until January 2016. Still aged 16, Souttar returned to the first team in April 2013 following an injury to Brian McLean and started for the remainder of the season, playing against Celtic in a 4–3 Scottish Cup semi-final defeat on 14 April 2013 at Hampden Park.
Souttar's form began to attract the attention of other clubs, with English Premier League team Sunderland having a bid of £600,000 accepted by Dundee United in October 2013. After speaking to Sunderland officials, Souttar decided to turn down the transfer. On 4 November 2013, Souttar signed another extension to his contract, keeping him at Dundee United until May 2016. Souttar continued to play in central defence throughout the 2013–14 season and scored his first goal for the club in a Scottish Premiership match against Aberdeen on 1 January 2014. Souttar missed the first three months of the 2014–15 season due to an ankle injury sustained in pre-season. After his return to the first team, Dundee United experimented with Souttar in a defensive midfield role in matches against Celtic and Aberdeen during April 2015, a position in which he has subsequently featured regularly. In October 2015, new United head coach Mixu Paatelainen played Souttar at right back in his first two matches in charge. In all he made seventy three appearances in all competitions, scoring twice.
On 1 February 2016, Souttar signed for fellow Scottish Premiership club Heart of Midlothian, agreeing a three and a half year contract for an undisclosed fee. Speaking about his move Souttar said that he was "looking forward to getting stuck in and getting my career back on track,"Souttar played for Hearts during the 2016–17 season until he suffered a ruptured achilles during a match against Celtic in January 2017, he suffered a similar injury during a Scottish Cup tie with Rangers in February 2020. Souttar has represented Scotland at under-17 level, making his debut on 28 August 2012, in a 0–0 draw against Belgium. In May 2013, Souttar made his debut against England. Alex McLeish called Souttar into the senior Scotland squad for the first time in May 2018, but he was forced to withdraw due to hip and hamstring injuries. In August 2018, Souttar's manager at Hearts, Craig Levein, suggested that Souttar may be called up for Australia if not selected for Scotland. Souttar admitted he had not considered playing for Australia or been contacted by Football Federation Australia, that he was unaware Levein was going to make the suggestion.
Souttar was again selected for Scotland in September 2018, he made his full international debut in a 4–0 defeat against Belgium on 7 September. As of match played 10 May 2019
The 2018 Utah House of Representatives election was held in the U. S. state of Utah on November 6, 2018, to elect members to the House of Representatives of the 63rd Utah State Legislature. A primary election was held in several districts on June 26, 2018; the election coincided with the election for U. S. Senate and other elections; the Utah Republican Party won a majority of seats, keeping the Republican majority that they have held since 1977. The new legislature convened on January 28, 2019. Republicans have held the Utah State House of Representative since 1977, the chamber was not considered competitive in 2018 However, as was the case in many states, Democrats were encouraged to see the purported "Blue Wave" come to the Utah State House; the 75 members of the House of Representatives were elected from single-member districts by first-past-the-post voting to two-year terms. Contested nominations of the Democratic and Republican parties for each district were determined by an open primary election.
Minor-party and independent candidates were nominated by petition. Write-in candidates had to file a request with the secretary of state's office for votes for them to be counted
Mazhar Ali Khan was a Pakistani socialist intellectual and a veteran journalist. He was the editor of the Pakistan Times in the 1950s, when it was considered a'progressive' newspaper. According to Dawn newspaper, "Mazhar Ali Khan was well known in his college days as a star debater, a lover of sports and as a leader of a nationalist-minded and non-communal students' union." He served as an officer in the British Indian Army. Sir Sikandar Hayat Khan unionist Chief Minister of Punjab in British India, had made that a condition for Mazhar Ali Khan before he could marry his beautiful daughter, Tahira. So he fulfilled that condition to be able to marry Tahira. Despite his feudal background, young Mazhar Ali Khan started mobilizing peasants that were working on his extended family's lands due to the prevailing influence and trend towards socialist thinking in the late 1940s, he was first asked to join the editorial team of the Pakistan Times in Lahore by owner Mian Iftikharuddin after the 1947 independence of Pakistan.
In 1951, when the newspaper editor Faiz Ahmed Faiz was arrested due to his suspected involvement in the Rawalpindi conspiracy case, Mazhar Ali Khan replaced him. Mian Iftikharuddin had earlier launched The Pakistan Times to rally and win Punjab's support for the Pakistan Movement and its cause, he remained its editor until 19 April 1959, when Ayub Khan's military regime seized the newspaper and its sister publications, the Urdu-language newspaper Daily Imroze and the magazine Lail-o-Nahar. Iftikharuddin, Faiz Ahmed Faiz and Mazhar Ali Khan developed the'progressive' editorial viewpoint of their publications from 1947 to 1959. Neither Faiz nor Mazhar joined a major political party in Pakistan so as not to compromise their editorial independence, they both tried to give special emphasis to the rights of workers. Mazhar Ali Khan's professional career may be divided into three parts – for the first 12 years, he wrote for The Pakistan Times which flourished under his editorial control and won the respect of the people.
Mazhar Ali Khan never joined a political party to be able to preserve his editorial independence. The owner of the newspaper, Mian Iftikharuddin deserves some credit here because he chose not to interfere in the editor's domain. Mazhar Ali Khan's emphasis was on truthfulness and objectivity Then he had a inactive period of 16 years, where he wrote an occasional column for different publications in Pakistan. In the final period of his life, he brought out and wrote for his weekly magazine Viewpoint from 1975 to 1993, the year of his death. In 1981, while he was jailed at Kot Lakhpat Jail, he continued writing his editorial for Viewpoint. Mazhar Ali Khan married his cousin Tahira. According to The Friday Times newspaper, "She eloped with her charismatic, student leader cousin Mazhar when she was 17, their marriage went on to become a fabled partnership." Tahira was the daughter of Punjabi feudal landlord and Unionist Party politician Sikander Hayat Khan who had served as provincial prime minister of Punjab in British India from 1937 to 1942.
After their marriage, Tahira stayed active and politically and was publicly known as Tahira Mazhar Ali. In the 1960s and 1970s, their son Tariq Ali became well- known as a British-Pakistani writer and a political activist with a socialist and communist viewpoint.

In mathematics, a complete lattice is a ordered set in which all subsets have both a supremum and an infimum. Complete lattices appear in many applications in mathematics and computer science. Being a special instance of lattices, they are studied both in universal algebra. Complete lattices must not be confused with complete partial orders, which constitute a more general class of ordered sets. More specific complete lattices are complete Heyting algebras. A ordered set is a complete lattice if every subset A of L has both a greatest lower bound and a least upper bound in; the meet is denoted by ⋀ A, the join by ⋁ A. Note that in the special case where A is the empty set, the meet of A will be the greatest element of L. Likewise, the join of the empty set yields the least element. Since the definition assures the existence of binary meets and joins, complete lattices thus form a special class of bounded lattices. More implications of the above definition are discussed in the article on completeness properties in order theory.
In order theory, arbitrary meets can be expressed in terms of arbitrary vice versa. In effect, this means that it is sufficient to require the existence of either all meets or all joins to obtain the class of all complete lattices; as a consequence, some authors use the terms complete meet-semilattice or complete join-semilattice as another way to refer to complete lattices. Though similar on objects, the terms entail different notions of homomorphism, as will be explained in the below section on morphisms. On the other hand, some authors have no use for this distinction of morphisms. Complete meet-semilattices have been defined as those meet-semilattices that are complete partial orders; this concept is arguably the "most complete" notion of a meet-semilattice, not yet a lattice. This discussion is found in the article on semilattices. A sublattice M of a complete lattice L is called a complete sublattice of L if for every subset A of M the elements ⋀ A and ⋁ A, as defined in L, are in M. If the above requirement is lessened to require only non-empty meet and joins to be in L, the sublattice M is called a closed sublattice of M.
Any non-empty finite lattice is trivially complete. The power set of a given set, ordered by inclusion; the supremum is given by the infimum by the intersection of subsets. The unit interval and the extended real number line, with the familiar total order and the ordinary suprema and infima. Indeed, a ordered set is compact as a topological space if it is complete as a lattice; the non-negative integers, ordered by divisibility. The least element of this lattice is the number 1; the greatest element is 0, because it can be divided by any other number. The supremum of finite sets is given by the least common multiple and the infimum by the greatest common divisor. For infinite sets, the supremum will always be 0 while the infimum can well be greater than 1. For example, the set of all numbers has 2 as the greatest common divisor. If 0 is removed from this structure it ceases to be complete; the subgroups of any given group under inclusion. If e is the identity of G the trivial group is the minimum subgroup of G, while the maximum subgroup is the group G itself.
The submodules of a module, ordered by inclusion. The supremum is given by the sum of the infimum by the intersection; the ideals of a ring, ordered by inclusion. The supremum is given by the sum of the infimum by the intersection; the open sets of a topological space, ordered by inclusion. The supremum is given by the union of the infimum by the interior of the intersection; the convex subsets of a complex vector space, ordered by inclusion. The infimum is given by the intersection of convex sets and the supremum by the convex hull of the union; the topologies on a set, ordered by inclusion. The infimum is given by the intersection of topologies, the supremum by the topology generated by the union of topologies; the lattice of all transitive relations on a set. The lattice of all sub-multisets of a multiset; the lattice of all equivalence relations on a set. The lattice of self-adjoint projections of a von Neumann algebra. A complete lattice L is said to be locally finite if the supremum of any infinite subset is equal to 1, or equivalently, the set is finite for any 1 ≠ x ∈ L.
The lattice is locally finite. Note that in this lattice, the element denoted "0" is 1 and vice versa; the traditional morphisms between complete lattices ar
