Define the following terms: data, database, DBMS, database system, database Catalog, program-data independence, user view, DBA, end user, canned transaction, deductive database system, persistent object, meta-data, and transaction-processing application. Data: Known facts that can be recorded and that have implicit meaning.
Database: A collection of related data with an implicit meaning.
DBMS: A collection of programs that enables users to create and maintain a database.
Database System: The database system not only contains the database itself but also a complete definition or description of the database structure and constraints. Database Catalog: The information about the database structure is stored in the Database Catalog which contains the structure of each file, the type and storage format of each data item, and various constraints on the data. Program-Data Independence: DBMS access programs do not require changes in all programs due to the change in the structure of a file because the structure of data files is stored in the DBMS catalog separately from the access programs. This property is called the Program-Data Independence.
User View: A database typically has many users, and each of whom may require a different perspective or view of the database. A view may be a subset of the database or it may contain virtual data that is derived form the database files but is not explicitly stored. This is called the user view. DBA: The responsibility of administering the primary resource database and the secondary resources like DBMS and the related software is handled by the Database Administrator (DBA). He is also responsible for authorizing access to the database, coordinating and monitoring its use and acquiring hardware and software resources as needed. The DBA is accountable for problems such as breach of security or poor system response time.

The credit crunch starting in September 2008 has grown into a global one primarily affecting car manufacturing and then it has its percussions in the whole economy-gradually reaching all the players. The crisis management in human resources implies layoffs, redundancies or shorter working hours and weeks. In many cases there were not wellthought corporate strategies for crisis management as managers as well as employees had to face a problem they had never experienced before. One of the corporate operative steps is to examine and realise how deeply the organisation itself is affected in the crisis. Our objective is to present what theoretical and practical solutions were or are invented besides the ones already mentioned. Keywords: crisis management, human resources management, atypical employment 1. About the crisis in general About a year ago the credit crunch became widespread primarily hitting the financial institutions worldwide and had its impacts felt in the motor industry reaching all players of the economic life.
