A SQL Knowledge Graph is the implementation of ontologies and graph theory in standard SQL. It has three components: (i) a virtual SQL ontology of connected, context-enriched concepts with inference capabilities and graph analytics features; (ii) a mapping of the virtual SQL ontologies to existing databases accessible in SQL and, (iii) a query execution engine that translates SQL queries of the ontology into SQL queries pushed down to the underlying databases. The SQL Knowledge Graph closes the gap between knowledge representation and enterprise databases/legacy systems/data warehouses/data lakes, to conveniently enable smart, semantic data fabrics and digital twins without need to change DBMS infrastructure.

Category: General

timbr offers a fast, easy and no-risk implementation of the semantic graph. The main reasons are that there’s no need to move data or learn any new proprietary query languages to work with the Knowledge Graph.

Modeling a SQL ontology can be done either manually or automatically from an ERD, OWL ontologies, or from data catalogs.

The mapping of the data to the Knowledge Graph is also done either manually or semi-automatically.

Category: General

Conceptual modeling is a representation of the real world. It is the first step of data modeling, a method developed to help with the design of databases and defining a formal vocabulary for the organization.

The process leading to the actual modeling and creation of databases leaves out information that is key to understanding and using data effectively. To make up for this information left behind, enterprises require coding complex queries in complex applications.

Ontologies are an effective means to re-create the information left behind, giving back business meaning to the data, simplifying data access and delivering unique analytical capabilities.

Category: General

An ontology defines a common vocabulary for an organization that needs to share information in a domain.
This includes machine-interpretable definitions of basic concepts in the domain and relations among them.

An ontology is structured as a graph, where every node on the graph represents a “concept.”
A concept could be anything: Person, Place, Customer, Car, Country, Product, Event etc.

Category: General

SQL ontologies are ontologies that implement the Semantic Web in SQL and are designed to provide common business meaning to data distributed in varied sources and enable them as concepts with inference and graph traversal capabilities to facilitate discovery, use and access to data.
With timbr, you can model and explore your ontology visually or in standard SQL. The SQL Ontology is exposed to the SQL user as a virtual schema with virtual tables (concepts) using any SQL client with JDBC/ODBC.

Category: General

Graph Data Exploration is a unique feature of timbr that automatically transforms non-graph data into a virtual graph to allow users to visualize and explore data relationships as a network. Data consumers, business analysts and domain experts can discover insights and answer questions without need of any coding.

A digital twin refers to a digital replica of potential and actual physical assets, processes, people, places, systems and devices that can be used for various purposes. The digital representation provides both the elements and the dynamics of how an Internet of things (IoT) device operates and lives throughout its life cycle.
Digital twins have two important characteristics.
1. each definition emphasizes the connection between the physical model and the corresponding virtual model or virtual counterpart.
2. this connection is established by generating real-time data using sensors.
timbr helps enterprises create digital twins by enabling the definition of the virtual model using SQL ontologies and by connecting the virtual model to data lakes that contain the sensor’s data. Contact us to schedule a demo to see why timbr facilitates the fastest and most convenient implementation of digital twins.

The Semantic Web is a project devised by Tim Berners Lee and James Hendler (et al), and adopted by the W3C (the manager of the Internet). The Semantic Web implements ontologies so that machines connected to the Web “understand” each other by sharing common meaning of data using a set of standards. The standards developed by the W3C define among others, an ontology modeling language (OWL) and a query language (SPARQL).

timbr implements the principles of the Semantic Web in standard SQL, meaning that both the ontology modeling and the queries are done in SQL.

Creating a SQL Knowledge Graph is a simple process:

1. Connect your databases to the virtual layer using JDBC connectors.

2. Model the SQL ontology visually or using timbr SQL DDL statements, or import from other sources (data catalogs, OWL ontologies, ERD tools).

3. Map the ontology concepts to the data.

That’s it, your SQL Knowledge Graph is ready for use and can start delivering unique insights via SQL queries, graph data exploration, your BI tools, or using timbr’s embedded charts and dashboard module.

The SQL Knowledge Graph serves as a virtual graph for all the enterprise data engines. Organizations use it to integrate, analyze and explore their data sources and silos of information without the need to move or transform data. Data consumers benefit from a 360° access to data to get fast answers to key business questions. By querying concepts instead of the tables, SQL queries are reduced in length and complexity significantly. The SQL Knowledge Graph seamlessly integrates with popular business intelligence tools so business analysts can focus on the business questions and derive deeper insights.

timbr is not a database. timbr is a platform used for creating virtual SQL Knowledge Graphs that enable semantic (ontology-based) graph capabilities on existing data engines (data warehouses and data lakes). The SQL Knowledge Graphs integrate data sources into a semantic data fabric queryable in SQL. timbr does not require to copy or transform data (no ETL operations), no new DBMS infrastructure and no new skills as required by graph databases.

Category: General

No, it is not possible. Property graphs use proprietary query languages lacking in semantics (unlike Knowledge Graphs which are based on RDF, SPARQL and OWL). Currently, timbr works with data engines that support SQL (mainly data warehouses and data lakes).

A knowledge graph is a knowledge base that uses a graph-structured data model or topology to integrate data. Knowledge graphs are often used to store interlinked descriptions of objects, events or concepts with free-form semantics. Knowledge graphs use ontologies to put data in context via linking and semantic metadata providing a framework for data integration, unification, analytics and sharing.

They are also prominently associated with and used by Google, Bing, and Yahoo, and with question-answering services such as Google Assistant, Siri and Alexa. All these examples were developed with proprietary tools.

For organizations that look to benefit from knowledge graphs, the available solutions in the market require significant changes in their IT departments. This is due to the fact that most of the data in the world is stored in formats that are not compatible with the format in which data is stored in knowledge graphs, so data needs to be extracted from its current DBMS, transformed to a new format and loaded into a separate, suitable DBMS. Another reason being is that to use knowledge graphs, data engineers and consumers need to acquire news skills to model in OWL and query in SPARQL.

Different from most other solutions, the timbr SQL Knowledge Graph platform creates a virtual layer that works in standard SQL to seamlessly connect to existing databases and is implemented without requiring new skills.

Gartner describes the data fabric architecture as the means of supporting “frictionless access and sharing of data in a distributed network environment.” To make this architecture work, it is necessary to implement a means to understand and assembly heterogeneous data by providing it with business meaning and flexibly integrating sources of any structural type. This is challenging due to several reasons, starting from the constraints of the architectural alternatives, and ending with the complexity to understand and query the aggregated sources.

The available options haven’t changed much in the last decade: Consolidating data into a data warehouse or graph-structured database, federating reporting, and data federation. Each alternative introduces implementation and operational constraints that involve investments in infrastructure and maintenance and varied skill sets. Moreover, till now there hasn’t been an integrative solution that resolves both the architectural and the “last mile” usability challenges, that is, encapsulating the complexity of the solution so data consumers across the enterprise conveniently gain a 360° view of data and easily generate complex queries to deliver advanced analytics and reporting conveniently and fast.

Data virtualization solutions are a viable solution to this challenge but their use is costly because of the continuous maintenance required to maintain indexes and because of the lack of relationship-rich semantic capabilities which are key to reduce complexity for end users and speed up  analytics that make use of dynamic data sources.

Knowledge representation is the field of artificial intelligence (AI) dedicated to representing information about the world in a form that a computer system can utilize to solve complex tasks such as diagnosing a medical condition or having a dialog in a natural language. Knowledge representation incorporates findings from psychology about how humans solve problems and represent knowledge in order to design formalisms that will make complex systems easier to design and build. Knowledge representation and reasoning also incorporates findings from logic to automate various kinds of reasoning, such as the application of rules or the relations of sets and subsets (Wikipedia).

Translated for the use of enterprises, knowledge representation provides the most efficient means for non-technical data consumers to access and retrieve data stored in databases (in the form of tables and columns for example), using abstract concepts that represent the real world (known as semantics in knowledge representation), such as “customer”, “product”, “employee”, “asset”, etc. This need arises from the fact that databases do not provide a means to use such concepts to give uniform meaning to data, because real world concepts such as “customer”, “product”, etc. are usually contained in several tables and columns or even multiple databases which are inaccessible to non-technical data consumers.

timbr enables knowledge representation and reasoning – a field of artificial intelligence, in SQL.

timbr’s AI features include:

  • Logical concept/object compositions combining objects or data types into more complex ones.
  • Contextual modeling that enables contextual adaptation required to construct models for classes of real-world phenomena.
  • Composition of semantic relationships.
  • A semantic reasoner that infers knowledge from semantic relationships.
Category: General

A virtual semantic graph is a layer that virtually integrates heterogeneous data from many sources and provides a common meaning to linked datasets. It focuses on the relationships between entities, is able to infer new knowledge out of existing information and makes possible advanced graph analytics. Timbr delivers these and additional data management capabilities.

SQL access to graph based solutions means that queries are created in SQL and then converted into SPARQL or other graph query language. For the most part, this means that there’s a need to create in advance a set of SPARQL queries or components which relate to SQL query statements, so constant maintenance and availability of SPARQL skilled personnel is required. In addition, the data is stored in a graph database so there’s a constant need to ETL data from the source to graph format.

In the case of a SQL knowledge graph, semantic SQL queries use the standard SQL commands and are not transalated into a separate graph query language. The data itself remains on site without need to be transformed.
