In 2015, I used to write extensions for Joomla, WordPress, phpBB3, etc and I didn't get rich from it but it did have 63K downloads (powered possible tens of thousands of websites).
In software engineering, the right architecture is essential for robust, scalable platforms. Wix has undergone a pivotal shift from event sourcing to a CRUD-based model for its microservices. This talk will chart the course of this pivotal journey.
Event sourcing, which records state changes as immutable events, provided robust auditing and "time travel" debugging for Wix Stores' microservices. Despite its benefits, the complexity it introduced in state management slowed development. Wix responded by adopting a simpler, unified CRUD model. This talk will explore the challenges of event sourcing and the advantages of Wix's new "CRUD on steroids" approach, which streamlines API integration and domain event management while preserving data integrity and system resilience.
Participants will gain valuable insights into Wix's strategies for ensuring atomicity in database updates and event production, as well as caching, materialization, and performance optimization techniques within a distributed system.
Join us to discover how Wix has mastered the art of balancing simplicity and extensibility, and learn how the re-adoption of the modest CRUD has turbocharged their development velocity, resilience, and scalability in a high-growth environment.

Globus Compute wth IRI Workflows - GlobusWorld 2024Globus
As part of the DOE Integrated Research Infrastructure (IRI) program, NERSC at Lawrence Berkeley National Lab and ALCF at Argonne National Lab are working closely with General Atomics on accelerating the computing requirements of the DIII-D experiment. As part of the work the team is investigating ways to speedup the time to solution for many different parts of the DIII-D workflow including how they run jobs on HPC systems. One of these routes is looking at Globus Compute as a way to replace the current method for managing tasks and we describe a brief proof of concept showing how Globus Compute could help to schedule jobs and be a tool to connect compute at different facilities.

Climate Science Flows: Enabling Petabyte-Scale Climate Analysis with the Eart...Globus
The Earth System Grid Federation (ESGF) is a global network of data servers that archives and distributes the planet’s largest collection of Earth system model output for thousands of climate and environmental scientists worldwide. Many of these petabyte-scale data archives are located in proximity to large high-performance computing (HPC) or cloud computing resources, but the primary workflow for data users consists of transferring data, and applying computations on a different system. As a part of the ESGF 2.0 US project (funded by the United States Department of Energy Office of Science), we developed pre-defined data workflows, which can be run on-demand, capable of applying many data reduction and data analysis to the large ESGF data archives, transferring only the resultant analysis (ex. visualizations, smaller data files). In this talk, we will showcase a few of these workflows, highlighting how Globus Flows can be used for petabyte-scale climate analysis.

3. What is a DBMS?
• Collection of interrelated data – manual or
computerized or online
• Set of programs to access the data
• DBMS provides an environment that is both
convenient and efficient to use.
3
4. Applications Areas of DBMS?
Banking: all transactions
Airlines: reservations, schedules
Universities: registration, grades
Sales: customers, products, purchases
Manufacturing: production, inventory, orders, supply chain
Human resources: employee records, salaries, tax
deductions
Databases touch all aspects of our lives
4
5. • To avoid data redundancy and inconsistency
Multiple file formats, duplication of information in
different files
• To avoid difficulty in accessing data
Need to write a new program to carry out each
new task
• To deal with data isolation — multiple files and
formats
• To deal with integrity problems
Integrity constraints (e.g. account balance > 0)
become part of program code
Easy to add new constraints or change existing
ones
Why do we use DBMS
5
6. 1. Atomicity of updates
• Failures may leave database in an inconsistent state with partial
updates carried out
• E.g. transfer of funds from one account to another should either
complete or not happen at all
2. Concurrent access by multiple users
• Concurrent accessed needed for performance
• Uncontrolled concurrent accesses can lead to inconsistencies
o E.g. two people reading a balance and updating it at the same
time
3. Security problems
Why do we use DBMS (contd..)

name
customer-id
customer-
street
customer-

9. Database Users
Users are differentiated by the way they expect to interact with the
system
• Application programmers – interact with system through DML
calls
• Sophisticated users – form requests in a database query
language
• Specialized users – write specialized database applications that
do not fit into the traditional data processing framework
• Naïve users – invoke one of the permanent application
programs that have been written previously
E.g. people accessing database over the web, bank tellers, clerical staff
9
10. Database Administrator
• Coordinates all the activities of the database
system
• Has a good understanding of the enterprise’s
information resources and needs.
• Database administrator’s responsibilities include:
Schema definition
Storage structure and access method definition
Schema and physical organization modification
Granting user authority to access the database
Specifying integrity constraints
Acting as liaison with users
Monitoring performance and responding to changes in
requirements
10
11. Transaction Management
• A transaction is a collection of operations that
performs a single logical function in a database
application
• Transaction-management component ensures that the
database remains in a consistent (correct) state
despite system failures (e.g., power failures and
operating system crashes) and transaction failures.
• Concurrency-control manager controls the interaction
among the concurrent transactions, to ensure the
consistency of the database.
11
12. Storage Management
• Storage manager is a program module that
provides the interface between the low-level
data stored in the database and the
application programs and queries submitted to
the system.
• The storage manager is responsible to the
following tasks:
interaction with the file manager
efficient storing, retrieving and updating of data
12
14. Application Architectures
Two-tier architecture: E.g. client programs using ODBC/JDBC
to communicate with a database
Three-tier architecture: E.g. web-based applications, and
applications built using “middleware”
14
16. SQL
Structured Query Language
The Language of DBMS
Standard language for querying and manipulating
data. Very widely used.
1. Data Definition Language (DDL)
– Create/alter/delete tables and their attributes
2. Data Manipulation Language (DML)
– Insert/delete/modify tuples in tables
17. SQL
• SQL: widely used non-procedural language
– E.g. find the name of the customer with customer-id 192-83-7465
select customer.customer-name
from customer
where customer.customer-id = ‘192-83-7465’
– E.g. find the balances of all accounts held by the customer with
customer-id 192-83-7465
select account.balance
from depositor, account
where depositor.customer-id = ‘192-83-7465’ and
depositor.account-number = account.account-number
• Application programs generally access databases through one of
– Language extensions to allow embedded SQL
– Application program interface (e.g. ODBC/JDBC) which allow SQL
queries to be sent to a database 17
19. Steps to Define the Schema

24. Specifying Attribute and Domain Constraints
• NOT NULL
NULL is not permitted for a particular attribute
• Default value
DEFAULT <value>
• CHECK clause
Dnumber > 0 AND Dnumber < 21;
• UNIQUE clause
Specifies attributes that have unique values 24
25. Specifying Key Constraints
• PRIMARY KEY clause
Specifies one or more attributes that make up the
primary key of a relation
It is an attribute or a combination of attributes that
that uniquely identifies the records./tuples
e.g. roll_no, account_no, Id etc.
