Vector overlay is an operation (or class of operations) in a geographic information system (GIS) for integrating two or more vector spatial data sets. Terms such as polygon overlay, map overlay, and topological overlay are often used synonymously, although they are not identical in the range of operations they include.
Additionally there is a single-row version, UPDATE OR INSERT INTO tablename (columns) VALUES (values) [MATCHING (columns)], but the latter does not give you the option to take different actions on insert versus update (e.g. setting a new sequence value only for new rows, not for existing ones.)
An HTML Application (HTA; file extension .hta) is a Microsoft Windows application that uses HTML and Dynamic HTML in a browser to provide the application's graphical interface. A regular HTML file is confined to the security model of the web browser's security, communicating only to web servers and manipulating only web page objects and site ...
.ID (Stores information linking graphic data to the database information. This contains a 4-byte integer index into the MAP file for each feature). Each time a *.MAP file is saved by MapInfo Professional its objects are sorted into a storage sequence based on an R-tree spatial index. This optimises the read process of streaming data from disk ...
A merge, or merger, is the process of uniting two or more pages into a single page.It is done by copying some or all content from the source page(s) into the destination page and then replacing the source page with a redirect to the destination page.
A three-way merge is performed after an automated difference analysis between a file "A" and a file "B" while also considering the origin, or common ancestor, of both files "C". It is a rough merging method, but widely applicable since it only requires one common ancestor to reconstruct the changes that are to be merged.
Insert(H,x), insert an element x into the heap H. Min(H), return the minimum element, or Nil if no such element exists. Extract-Min(H), extract and return the minimum element, or Nil if no such element exists. And one more that distinguishes it: [1] Merge(H1,H2), combine the elements of H1 and H2 into a single heap.
Mail merge consists of combining mail and letters and pre-addressed envelopes or mailing labels for mass mailings from a form letter. [1]This feature is usually employed in a word processing document which contains fixed text (which is the same in each output document) and variables (which act as placeholders that are replaced by text from the data source word to word).
