What happened to Caiaphas after Jesus' death?
Matthew 27:5 says that Judas threw down the silver in the Temple and went and hanged himself. The priests took the blood money and bought the potter's field, which they called the field of blood.Acts 1:18 has a different story, that Judas bought a field with the reward of iniquity, and fell headlong, bursting asunder and all his bowels gushed out. Because of this, the field was called the field of blood.In other words, neither Matthew nor Luke knew how Judas Iscariot died, but Matthew seems to have got his story from the Book of Zechariah. The Acts account says that he died by misadventure in the field that he bought, but in Matthew's account, he could have committed suicide anywhere.

Which type of database model connects data in different files through the use of a key field?
The relational database model connects data through the use of a key field, which is called a primary key in one table and a foreign key in another table. This key field establishes a relationship between different tables by uniquely identifying records.
What problems are caused by data redundancy?
Data redundancy is a data organization issue that allows the unnecessary duplication of data within your Microsoft Access database. A change or modification, to redundant data, requires that you make changes to multiple fields of a database. While this is the expected behaviour for flat file database designs and spreadsheets, it defeats the purpose of relational database designs. The data relationships, inherent in a relational database, should allow you to maintain a single data field, at one location, and make the database's relational model responsible to port any changes, to that data field, across the database. Redundant data wastes valuable space and creates troubling database maintenance problems
What is the relationship between a record and a field?
In a database, a "record" is a collection of fields and all records in a "flat" databse are the same size and name, but with different data. In a relational database, a field can be a key to another table of records. A field is one data item, an index (or Key), a date, a name, etc. A record: Index,Name,Date,Acount A field: Name

What is field in dbms?
In a database management system (DBMS), a field is a unit of data that represents an attribute of an entity.

Each field is defined with a specific data type and constraints to ensure data integrity and accuracy.
Can you group a field twice in excel For example I have the field of states but I want to make multiple 'Region' groups as there are three sets of regions each including all 50 statesin my company?
What you really need is to set it up in a relational database. It is not a good idea to duplicate data or fields, as it can lead to problems. If you have a relational database then you can have each region in one table and the states in another and then set up relations between them. It can be complicated, but it is the better way to do it. Study up on relational databases and in particular many to many relationships as this what you particular scenario needs.
Disadvantages of logical data modelling?
1. Database may need completely redoing if a single field in one relational table has to be changed. 2. If an ERD is resolved incorrectly then it would have to be redone.
What is the difference between database and relational database?
A database is something that stores data. Using tools called Database Management Systems(like Oracle, Informix, Sybase, DB2), you can create, view, modify, and delete databases. Databases can be -Relational -Object Oriented -Object Relational Relational database stores data in tables(called realtions). These tables are related to each other.Just like in our family, our relations are related with each other. In Object Oriented Databases, the information is stored in the form of Objects as in Object Oriented Programming.OODBMS makes database objects appear as programming language objects in one or more porgramming languages. Object relational databases combine the features of both Object Oriented as well as Relational databases. Here you can not only store simple data like text in relational, but you can also store complex objects like images, audio and video in tables.

How are field record table and relational database relate to one another in Access?
A table stores data. Tables have fields in them, like name, address, date of birth etc. They are often likened to columns. One individual set, like your name, address and date of birth is a record. So tables have records in them. In a relational database there is more than one table and these tables are related to each other. So one table might store all your personal details and another my store all your employment details. By having at least one common field, like an employee number, these two tables can be related to each other. Access is a database application and has the capability to create relational databases.
What is a database field name?
A database field name is a unique identifier for a particular piece of data within a database table. It helps to organize and distinguish different types of information stored in the database. Each field name typically corresponds to a specific attribute or characteristic of the data being stored.
