Logic Works
Logic Works Inc. was a software company created by CEO Benjamin C. Cohen based in Princeton, New Jersey. Their flagship product was an IDEF1X modeling and database design tool called ER''win'' (ERwin) whose name is formed from an initialism of ER for Entity Relationship and "win", short for windows. The company also produced BP''win'' (for business process modeling using IDEF0), ModelMart and TestBytes. The company went public in October 1995 with an IPO of 3.2 million shares at $11, and was traded on the NASDAQ under the symbol LGWX until its eventual sale. In 1998, Logic Works was acquired by Platinum Technology for $174.8 million in stock, which was in turn acquired by Computer Associates the next year. In 2016, erwin, Inc. was launched as an independent company.{{Cite web, url=http://www.erwin.com, title=erwin, Inc. {{!

AllFusion ERwin Data Modeler
erwin Data Modeler (stylized as erwin but formerly as ERwin) is computer software for data modeling. Originally developed by Logic Works, erwin has since been acquired by a series of companies, before being spun-off by the private equity firm Parallax Capital Partners, which acquired and incorporated it as a separate entity, erwin, Inc., managed by CEO Adam Famularo. The software’s engine is based on the IDEF1X method, although it now also supports diagrams displayed with a variant information technology engineering notation, as well as a dimensional modeling notation. History ERwin was created by Logic Works, which was based in Princeton, New Jersey. In May 1993, Logic Works released ERwin/ERX, a version of the tool designed to work in conjunction with PowerBuilder. The database models created using ERwin could be translated into software built through the PowerBuilder integrated development environment (IDE). In May 1995, Logic Works ERwin was expanded to include several o ...

Initial Public Offering
An initial public offering (IPO) or stock launch is a public offering in which shares of a company are sold to institutional investors and usually also to retail (individual) investors. An IPO is typically underwritten by one or more investment banks, who also arrange for the shares to be listed on one or more stock exchanges. Through this process, colloquially known as ''floating'', or ''going public'', a privately held company is transformed into a public company. Initial public offerings can be used to raise new equity capital for companies, to monetize the investments of private shareholders such as company founders or private equity investors, and to enable easy trading of existing holdings or future capital raising by becoming publicly traded. After the IPO, shares are traded freely in the open market at what is known as the free float. Stock exchanges stipulate a minimum free float both in absolute terms (the total value as determined by the share price multiplied by the ...

Software Companies Established In 1988
Software is a set of computer programs and associated documentation and data. This is in contrast to hardware, from which the system is built and which actually performs the work. At the lowest programming level, executable code consists of machine language instructions supported by an individual processor—typically a central processing unit (CPU) or a graphics processing unit (GPU). Machine language consists of groups of binary values signifying processor instructions that change the state of the computer from its preceding state. For example, an instruction may change the value stored in a particular storage location in the computer—an effect that is not directly observable to the user. An instruction may also invoke one of many input or output operations, for example displaying some text on a computer screen; causing state changes which should be visible to the user. The processor executes the instructions in the order they are provided, unless it is instructed to ...

Companies Disestablished In 1998
A company, abbreviated as co., is a legal entity representing an association of people, whether natural, legal or a mixture of both, with a specific objective. Company members share a common purpose and unite to achieve specific, declared goals. Companies take various forms, such as: * voluntary associations, which may include nonprofit organizations * business entities, whose aim is generating profit * financial entities and banks * programs or educational institutions A company can be created as a legal person so that the company itself has limited liability as members perform or fail to discharge their duty according to the publicly declared incorporation, or published policy. When a company closes, it may need to be liquidated to avoid further legal obligations. Companies may associate and collectively register themselves as new companies; the resulting entities are often known as corporate groups.
