A vector database, vector store or vector search engine is a database that can store vectors (fixed-length lists of numbers) along with other data items. Vector databases typically implement one or more Approximate Nearest Neighbor algorithms, [1] [2] [3] so that one can search the database with a query vector to retrieve the closest matching database records.
Overview of a data-modeling context: Data model is based on Data, Data relationship, Data semantic and Data constraint. A data model provides the details of information to be stored, and is of primary use when the final product is the generation of computer software code for an application or the preparation of a functional specification to aid a computer software make-or-buy decision.
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 ).
C, The Complete Reference [1] is a book on computer programming written by Herbert Schildt. The book gives an in-depth coverage of the C language and function libraries features. [2] [3] The first edition was released by Osbourne in 1987. The current version is 4th. Last revision: January 13th, 2018. [4]
TerminusDB is an in-memory graph database management system with a rich query language. The design of the underlying data structure , which is implemented in a Rust library , uses a succinct data structures and delta encoding approach drawing inspiration from software source control systems like Git .

The following is provided as an overview of and topical guide to databases: Database – organized collection of data, today typically in digital form. The data are typically organized to model relevant aspects of reality (for example, the availability of rooms in hotels), in a way that supports processes requiring this information (for example, finding a hotel with vacancies).
Traits are one common programming language technique to support method injection. Some languages, such as Scala, have native support for traits, while other languages (e.g., Ruby and Python) allow run time injection of methods. In Java, pre-compiler tricks based on annotations are needed to support DCI.
Object–relational mapping (ORM, O/RM, and O/R mapping tool) in computer science is a programming technique for converting data between a relational database and the memory (usually the heap) of an object-oriented programming language. This creates, in effect, a virtual object database that can be used from within the programming language.
