Trust Store
A trust store is a list of root certificates (sometimes called trust anchors) that comes pre-installed on a device. It’s composed of more than a hundred of the largest and most trusted CAs such as Digicert, Apple, Microsoft, Symantec, Mozilla, Lets Encrypt, and more.

It serves a couple of very important purposes. First, they sign (validate) the identity of the device for other certificate authorities. The root CAs know the public key of the device and can confirm to any third parties.

Secondly, they “inoculate” the device with trusted certificate authorities. Without pre-installed certificates, the device would have to accept a certificate that wasn’t initially verifiable and just “take their word for it”, and that would be a potential vector for malicious actors to inject a false certificate.

Certificate authorities rarely sign certificates using the root CA directly. Instead they put one or more levels of separation between themselves and the client by creating intermediate certificate authorities. Intermediate CAs are functionally identical, but they have less “authority” because they are responsible for signing fewer certificates. Theoretically, they are just as trustworthy, but in the case that they are compromised, it limits the damage that can be caused.

Anitech future

The future is the time after the past and present. Its arrival is considered inevitable due to the existence of time and the laws of physics. Due to the apparent nature of reality and the unavoidability of the future, everything that currently exists and will exist can be categorized as either permanent, meaning that it will exist forever, or temporary, meaning that it will end.[1] In the Occidental view, which uses a linear conception of time, the future is the portion of the projected timeline that is anticipated to occur.[2] In special relativity, the future is considered absolute future, or the future light cone.[3]

In the philosophy of time, presentism is the belief that only the present exists and the future and the past are unreal. Religions consider the future when they address issues such as karma, life after death, and eschatologies that study what the end of time and the end of the world will be. Religious figures such as prophets and diviners have claimed to see into the future. Future studies, or futurology, is the science, art, and practice of postulating possible futures. Modern practitioners stress the importance of alternative and plural futures, rather than one monolithic future, and the limitations of prediction and probability, versus the creation of possible and preferable futures. Predeterminism is the belief that the past, present, and future have been already decided.

Anitech SQL

What are SQL commands?
Structured query language (SQL) commands are specific keywords or SQL statements that developers use to manipulate the data stored in a relational database. You can categorize SQL commands as follows.

Data definition language
Data definition language (DDL) refers to SQL commands that design the database structure. Database engineers use DDL to create and modify database objects based on the business requirements. For example, the database engineer uses the CREATE command to create database objects such as tables, views, and indexes.

Data query language
Data query language (DQL) consists of instructions for retrieving data stored in relational databases. Software applications use the SELECT command to filter and return specific results from a SQL table.

Data manipulation language
Data manipulation language (DML) statements write new information or modify existing records in a relational database. For example, an application uses the INSERT command to store a new record in the database.

Data control language
Database administrators use data control language (DCL) to manage or authorize database access for other users. For example, they can use the GRANT command to permit certain applications to manipulate one or more tables.

Transaction control language
The relational engine uses transaction control language (TCL) to automatically make database changes. For example, the database uses the ROLLBACK command to undo an erroneous transaction.
