  • Not ACID, Not BASE, but SALT a Transaction Processing Perspective on Blockchains
    Not ACID, not BASE, but SALT A Transaction Processing Perspective on Blockchains Stefan Tai, Jacob Eberhardt and Markus Klems Information Systems Engineering, Technische Universitat¨ Berlin fst, je, [email protected] Keywords: SALT, blockchain, decentralized, ACID, BASE, transaction processing Abstract: Traditional ACID transactions, typically supported by relational database management systems, emphasize database consistency. BASE provides a model that trades some consistency for availability, and is typically favored by cloud systems and NoSQL data stores. With the increasing popularity of blockchain technology, another alternative to both ACID and BASE is introduced: SALT. In this keynote paper, we present SALT as a model to explain blockchains and their use in application architecture. We take both, a transaction and a transaction processing systems perspective on the SALT model. From a transactions perspective, SALT is about Sequential, Agreed-on, Ledgered, and Tamper-resistant transaction processing. From a systems perspec- tive, SALT is about decentralized transaction processing systems being Symmetric, Admin-free, Ledgered and Time-consensual. We discuss the importance of these dual perspectives, both, when comparing SALT with ACID and BASE, and when engineering blockchain-based applications. We expect the next-generation of decentralized transactional applications to leverage combinations of all three transaction models. 1 INTRODUCTION against. Using the admittedly contrived acronym of SALT, we characterize blockchain-based transactions There is a common belief that blockchains have the – from a transactions perspective – as Sequential, potential to fundamentally disrupt entire industries.

  • Polymorphic Stored Procedure? Venkat Subramaniam [email protected]
    Polymorphic Stored Procedure? Venkat Subramaniam [email protected] http://www.durasoftcorp.com/download Abstract A typical user of JDBC or ASP.NET issues a SQL query to the underlying database, grabs the fields returned by the record set/result set (or dataset) and then populates an object with the data fetched. Not considering the use of Entity Beans and JDO in Java, what does one do if the object being fetched is one of several types derived from a common base type? This article addresses one way this can be solved in an extensible manner. A Simple Data Access Scenario For some one who has spent significant time developing OO applications that used object-oriented databases and those that did not use any database at all, it is painful to use a relational database with objects. I am sure you have heard people with OODBMS experience talk about data access impedance mismatch when it comes to storing an object in a relational database. You hear less of this now than you did in the early nineties. While there is some market for ODBMS still, I have come to agree that relational databases are here to stay. After developing a couple of applications using relational databases, I was pondering about arriving at a solution to the problem of mapping the inheritance hierarchy in an extensible way. Is this really a good approach to follow, is for you to decide. I simply present here my thoughts on what I tried recently. Your comments are most welcome. Let’s consider a database with four tables: Customer, Account, CheckingAccount, SavingsAccount.

  • 2.2 Update, Insert, Delete Stored Procedure Examples
    SYSTEMS DESIGN / CAPSTONE PROJECT MIS 413 User Guide 2.2 Creating Update, Insert and Delete Stored Procedures This guide will demonstrate building Insert, Update and Delete Stored Procedures with a few input parameters using the Query Editor Tool. They all assume you have a person table with a personID (auto number), FN, LN, Email, PWD attributes. Example A: Update Stored Procedure The easiest manner to create a stored procedure is to let the wizard in SQL assist you. 1) Open SQL and the proper database 2) Expand the ‘programmability’ tab under your database 3) Right click on stored procedures and click ‘new stored procedure’ 4) Consistent and proper naming of your stored procedure will help you and future developers understand their purpose. A guideline for this class would be: Name of the Table, the Operation (select, update, etc.), Optional Word(s) as in: personUpdate 5) Add your name of the procedure (without the < > brackets) as in: CREATE PROCEDURE personUpdate in the first row of the stored procedure. 6) To build your first UPDATE, use the Design in Query Editor Option. Delete the following row in your Stored Procedure: SELECT <@Param1, sysname, @p1>, <@Param2, sysname, @p2> 7) Then right click in the blank area and select DESIGN IN QUERY EDITOR A dialog box will appear and select the name of the table to be updated. A general rule is you will only UPDATE one table at a time. Do not try to UPDATE 2 or more tables with one UPDATE statement. If you need to update more than one table, you can do two separate UPDATE statements in the same Stored Procedure.

Calculators are NOT allowed in this examination. Section A Answer Section A questions in Answer Book A A1 Examiner's General Comments This was a fairly popular question, attempted by around half of the candidates, with two-thirds of the attempts achieving pass level marks. Therefore, the performance was generally quite good with a wide range of marks, some candidates producing near correct solutions. The definition of a true distributed database system is that it consists of a collection of geographically remote sites of physical databases, connected together via some kind of communication network, in which a user at any site can access data anywhere in the network exactly as if the data were all stored in one single database at the user’s own site. a) Explain the problems associated with achieving a true distributed database in practice. 12 marks ANSWER POINTER Fragmentation of tables requires maintenance of unique keys across horizontal fragments and consistency of primary keys that are reflected in vertical fragments. Also increased network traffic occurs as many fragments may need to be consulted to perform one query.
