.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 ...
Besides differences in the schema, there are several other differences between the earlier Office XML schema formats and Office Open XML. Whereas the data in Office Open XML documents is stored in multiple parts and compressed in a ZIP file conforming to the Open Packaging Conventions, Microsoft Office XML formats are stored as plain single monolithic XML files (making them quite large ...
SAP IQ also supports plugging in external algorithms written in C++ and Java. SQL queries can call these algorithms, allowing for the execution of in-database analytics, which provides better performance and scalability. Additionally, Sybase IQ also provides drivers for access via languages such as PHP, Perl, Python, and Ruby on Rails.
to enable the use of automated refactoring or search and replace tools with minimal potential for error; to enhance clarity in cases of potential ambiguity; to enhance the aesthetic and professional appearance of work product (for example, by disallowing overly long names, comical or "cute" names, or abbreviations);

SAP is a file format that stores music data from Atari 8-bit computers, all of which use the POKEY sound chip.Most popular tunes were written between 1981-1987. The format is similar to the SID, SPC or NSF formats, in that it is a music data format which is supported by a player, which emulates the central processing unit and sound hardware of the original hardware in order to play music.
Each cell of a bigtable can have zero or more timestamped versions of the data. Another function of the timestamp is to allow for both versioning and garbage collection of expired data. Tables are split into multiple tablets – segments of the table are split at certain row keys so that each tablet is a few hundred megabytes or a few gigabytes ...
That is why, when performing k-means, it is important to run diagnostic checks for determining the number of clusters in the data set. Convergence to a local minimum may produce counterintuitive ("wrong") results (see example in Fig.). A key limitation of k-means is its cluster model. The concept is based on spherical clusters that are ...
