The database schema is the structure of a database described in a formal language supported typically by a relational database management system (RDBMS). The term " schema " refers to the organization of data as a blueprint of how the database is constructed (divided into database tables in the case of relational databases ).
SourceForge reported 30 million downloads for the Apache OpenOffice 3.4 series by January 2013, making it one of SourceForge's top downloads; [125] the project claimed 50 million downloads of Apache OpenOffice 3.4.x as of 15 May 2013, slightly over one year after the release of 3.4.0 (8 May 2012), [126] 85,083,221 downloads of all versions by 1 ...
The generated diagram (a wikitable) has been designed and improved by many earlier editors on many wiki pages. This template merely standardizes this work and simplifies its use. The diagram includes a header that numbers bits from 0 to 31, with 0 being the most significant bit.
The database design documented in these schemas is converted through a Data Definition Language, which can then be used to generate a database. A fully attributed data model contains detailed attributes (descriptions) for every entity within it. The term "database design" can describe many different parts of the design of an overall database ...
The Apache project removed or replaced as much code as possible from OpenOffice.org 3.4 beta 1, including fonts, under licenses unacceptable to Apache [228] and released 3.4.0 in May 2012. [ 126 ] The codebase for IBM's Lotus Symphony was donated to the Apache Software Foundation in 2012 and merged for Apache OpenOffice 4.0, [ 229 ] and ...
Apache Cassandra is a free and open-source database management system designed to handle large volumes of data across multiple commodity servers. The system prioritizes availability and scalability over consistency , making it particularly suited for systems with high write throughput requirements due to its LSM tree indexing storage layer.

A graph database is a database that is based on graph theory. It consists of a set of objects, which can be a node or an edge. It consists of a set of objects, which can be a node or an edge. Nodes represent entities or instances such as people, businesses, accounts, or any other item to be tracked.
Tabular data is two dimensional — data is modeled as rows and columns. However, computer systems represent data in a linear memory model, both in-disk and in-memory. [7] [8] [9] Therefore, a table in a linear memory model requires mapping its two-dimensional scheme into a one-dimensional space.
