If the heterogeneity exists in the system, then two implementation alternatives exists unilingual and multilingual. The 'Schema Architecture & Engineering' team participated in the 'Open House' weekend (15-17 April 2016) with the 'Microbiology Lab in Lambrini'. Open House is one of the most important global institutions for the promotion of architecture. As we came to know that there are three different types of schema in the database and these are defined according to the levels of abstraction of the three-level architecture portrayed in the above figure, at the highest level, there is multiple external schemas (view level schema) (also called sub-schemas) that match up to different views of the data.

Schema Integration : How to Integrate Static and Dynamic Database Schemata is the task of integrating several local schemata into one global database schema. Enterprise Software System Integration : An Architectural Perspective.
This is known as Abstraction. The database divided into three-level architecture is also known as three; schema architecture. Database scheme is contained attributes and instructions to handle how data will be stored and how data related to each other and how can we access the data.

Schema translation from the local schema to the component schema is accompanied by generating mappings to transform commands Developed in the 1970s, the three-schema architecture helps to evaluate a relational database from different vantage points. The first of the three levels is called the external level or user level. This is the view of the relational database that end users see, and it involves a high level of abstraction. The second level is the logical schema or conceptual level, where designers work.

The global conceptual schema is a logical description. of the whole database, as if it were not distributed. This level corresponds to the conceptual level of the ANSI-SPARC architecture and contains definitions of entities, relationships, constraints, security and integrity information .

external level 2.conceptual level and, 3.internal level External Level is described by a schema i.e. it consists of definition of logical records Global Schema How it works Unlike traditional data platforms that require data to be either centralised or shared with a third-party to achieve analysis across multiple datasets, InfoSum’s identity infrastructure provides a secure and privacy-safe way to connect first and second-party data sources, without moving data. This architecture generally has four levels of schemas − Global Conceptual Schema − Depicts the global logical view of data. Local Conceptual Schema − Depicts logical data organization at each site. Local Internal Schema − Depicts physical data organization at each site.
Le schéma d'architecture peut aider les designers et les dévelopeurs du système de visualiser le haut niveau, la structure globale de leur système ou d'application, afin d'assurer que le système répond aux besoins de leurs utilisateurs. À l'aide de schéma d'architecture, vous pouvez aussi décrire des modèles qui sont utilisés tout au long de la conception.

The logical architecture allows a user to identify as a single Logical Schema a group of similar physical schemas - that is containing datastores that are structurally identical - but located in different physical locations. Logical Schemas, like their physical counterpart, are attached to a technology.
