We are building EduLadder(ELADR) - Protocol

The Eladr Protocol is a decentralized, security and efficiency enhanced Web3 noSQL database powered by IPFS as the data storage layer https://ipfs.io/, and the Cardano block chain as the rewards token platform, https://cardano.org/. It provides a JSON based, IPFS layer 2 solution for data indexing and retrieval in an 'append only' file system built with open source Node.js API libraries.

The ELADR token was designed to incentivize and reward community members as a proof of contribution. Token holders are also granted access to EduLadder.com premium features as well as associated ELADR token enabled apps.

How to study this subject

Teradata is a relational database management system (RDBMS) that drives a company's data warehouse. Teradata provides the foundation to give a company the power to grow, to compete in today's dynamic marketplace, to achieve the goal of "Transforming Transactions into Relationships" and to evolve the business by getting answers to a new generation of questions. Teradata's scalability allows the system to grow as the business grows, from gigabytes to terabytes and beyond. Teradata's unique technology has been proven at customer sites across industries and around the world.

Teradata is an open system, compliant with ANSI standards. It is currently available on UNIX MP-RAS and Windows 2000 operating systems. Teradata is a large database server that accommodates multiple client applications making inquiries against it concurrently. Various client platforms access the database through a TCP-IP connection across an IBM mainframe channel connection. The ability to manage large amounts of data is accomplished using the concept of parallelism, wherein many individual processors perform smaller tasks concurrently to accomplish an operation against a huge repository of data. To date, only parallel architectures can handle databases of this size.

2. What is Teradata ?

Teradata is a relational database management system initially created by the firm with the same name, founded in 1979. Teradata is part of the NCR Corporation which acquired the Teradata company on February 28, 1991. It is a massively parallel processing system running a shared nothing architecture. The main point with the Teradata DBMS is that it's linearly and predictably scalable in all dimensions of a database system workload (data volume, breadth, number of users, complexity of queries), explaining its popularity for enterprise data warehousing applications. Teradata is offered on Intel servers interconnected by the BYNET messaging fabric. Teradata systems are offered with either Engenio or EMC disk arrays for database storage.

Teradata offers a choice of several operating systems

NCR UNIX SVR4 MP-RAS, a variant of System V UNIX from AT&T Microsoft Windows 2000 and Windows Server 2003 SUSE Linux on 64-bit Intel servers has been pre-announced for 2006. Teradata Enterprise Data Warehouses are often accessed via ODBC or JDBC by applications running on operating system such as Microsoft Windows or flavors of UNIX. The warehouse typically sources data from operational systems via a combination of batch and trickle loads.

The largest and most prominent customer of this DBMS is Wal-Mart, which runs its central inventory and other financial systems on Teradata. Wal-Mart's Teradata Data Warehouse is generally regarded by the DBS industry as being the largest data warehouse in the world. Other Teradata customers include companies like AT&T (formerly SBC), Dell, Continental Airlines, National Australia Bank, FedEx, Vodafone, Gap Inc, Safeway Inc, eBay and Kaiser Permanente.

Teradata's main competitors are other high-end solutions such as Oracle and IBM's DB2.
